How to Keep Horse Flies Away from Your Yard

Horse flies are well-known for their painful bites, which are caused by their scissor-like jaws. Female horse flies, like female mosquitoes, are attracted to your blood because it provides them with nutrition. (Male horse flies are attracted to nectar mostly.) A horse fly bite, on the other hand, will result in a loud “ouch!” unlike a mosquito bite, which may not be recognized until it begins to itch. If you have a problem with horse flies in your yard, follow these guidelines to help protect yourself, your family, and your pets (or livestock).

What Do Horse Flies Look Like?

As one of the biggest flies on the planet, they are reasonably easy to detect, yet they can be tough to thwart due to their size. In order to establish whether or not you have horse flies, look for the following features. Horse flies have extremely huge and robust bodies that range in length from 3-4 inches to 1-14 inches. A variety of colors are available, ranging from dark brown to grey to black. Their eyes are huge and can be either green or black in color.

Maintain Your Yard

Because horse flies like moist regions and hot temperatures, they can be seen in large numbers in pasturelands near creeks throughout the summer months. They prefer weedy patches and tall grass around dwellings because they can retain moisture and help to reproduce the humid pasture habitat that they adore so much. Horse flies may also be a nuisance for folks who spend their time at the beach or at the local pool.

Remove Garbage

Horse flies, like other fly species, will concentrate their efforts on waste in search of food. The lids of outdoor garbage cans should have a tight fit. Keeping your garbage in your garage may help to reduce the number of flies that fly over your yard.

Clean Up after Pets

Horse flies, like many other insects, are drawn to the excrement of domesticated animals. The summer months will necessitate more regular yard cleanups if you have a canine companion, otherwise you may find yourself with a horse fly infestation on your hands.

Burn CandlesTorches

If you’re hosting a backyard BBQ or other outdoor celebration, burning citronella candles and lighting torches will help keep horse flies away from your guests and prevent them from attacking them. Horse flies are attracted to the smoke and aroma created by citronella oil, so using it can help keep them away.

Kill and Prevent Horse Flies

Horse flies (Tabanidae) are huge, aggressive insects that fly quite quickly. They are also highly spry flyers. Horse flies are among the biggest of all fly species, and there are around 3,000 different species of Horse flies in the globe. Females attack people and other animals (particularly horses and other livestock) in the hopes of obtaining blood meals for their young. Horse flies and Bot flies are referred to as “gadflies” in some circles. Horse flies might be a nuisance, but remember that you are not alone in feeling this way.

They were also a source of concern for the Vikings. But don’t be concerned. Continue reading for the most crucial facts about horse flies, as well as information on how to put preventative measures in place to keep you and your family safe from horse flies.

What Do Horse Flies Look Like?

Horse flies are available in a variety of colors ranging from yellowish-brown to dark grey to blackish in appearance, and they normally reach 3/4″ to 1.25″ in length. Their heads are disproportionately large in comparison to the rest of their bodies, and they are hairy all over, giving them a passing similarity to honey bees in appearance. They have just one set of wings, like all other genuine flies of theDipteraorder, which are delicately colored and covered with wispy dots, much like all other true flies of theDipteraorder.

Horse Flies vs. Deer Flies

Horse flies are frequently mistaken with Deer flies, which are also known to attack humans on a regular basis. Horse flies and Deer flies both have vividly colored eyes, however Deer flies are somewhat smaller than Horse flies. They are distinguished by the black stripes that run across their wings.

Where doHorse FliesCome From?

Aside from the polar extremes and few islands, such as Hawaii, horse flies may be found almost wherever on the planet, including the tropics. These fly prefer warm, wet environments where they may reproduce, although they can be found in a broad range of habitats, including deserts and alpine meadows, depending on the species. Horse flies are strictly outside creatures, and they do not feed or seek shelter indoors unless it is necessary. You may come across one who has mistakenly walked inside your home through an open window or door, in which case a flyswatter or a dependable indoor and outdoor fly spray will make fast work of it.

Horse Fly Habits

Most of the time, these flies may be found in valley meadows near creeks and streams, where they enjoy higher temperatures and more moisture, as well as regions where cattle and people can be located outside. Horse flies are not simply attracted to the open air (especially near pools of water, like mosquitoes). They also love bright sunshine and are most common throughout the summer months, and they seek to avoid dark, shaded regions when possible. Horse flies do not emerge from their lairs at night.

Females are the only ones who bite, as they have powerful, incisor-like mouthparts, whereas males have weak mouthparts, as shown in the photo.

During their development, horse fly larvae live in aquatic or semi-aquatic settings, where they prey on other smaller organisms.

What AttractsHorse Flies?

Female Horse flies can identify humans and animals by their colors and motions, and they are drawn to bright items, warmth, perspiration, and carbon dioxide emitted by humans and animals, among other things.

Can Horse Flies Bite?

Female horse fly bites are extremely painful, but what’s worse is that these insects have the ability to transmit germs and blood pollutants from one host to another. They have the potential to make animals and people severely ill, and in unsheltered cattle, they can even cause growth rates and milk supply to be lowered. If the person or animal who has been bitten has an allergy, the consequences are more severe. Blood-stained horse fly bites on people can cause rashes, dizziness, weakness, and wheezing, as well as other symptoms such as headaches and fatigue.

Likewise, scratching will exacerbate the itching and other side effects of mosquito bites. In most cases, symptoms from a bite may subside within a few hours, but if an infection develops, seek medical assistance immediately.

Will Horse Flies Bite Your Dogs?

The scissor-like mouth of the female Horse fly can inflict painful bites not only on humans, but also on your dog. Even though the effects and minor irritation are only short-lived, your dog is still at risk for the same danger that comes with all biting pests: the spread of bacteria and other blood contaminants from the female Horse fly’s saliva. In addition to the belly, legs, and neck, larger dog breeds are the most prone to Horse fly attacks. The most common regions where dogs get attacked are the legs, abdomen, and neck.

TheHorse FlyLife Cycle

Female Horse flies deposit their eggs under gravel or plants in close proximity to a water source, but they do not need to be close to it. When the eggs hatch, the pale, spindly larvae crawl into a nearby body of water or moist soil, where they feed on tiny insects and even reptiles for the rest of their lives. When the horse fly larval stage is complete, it can continue up to a year, at which point the larvae burrow themselves into the earth in order to pupate. Horse flies mature after one to two weeks as pupae and another three to ten weeks as developing adults before emerging as fully fledged adults.

Helping Prevent a Horse Fly Problem Outdoors

Horse fly problems in suburban regions are less prevalent than in less-populated, rural locations, where there may be grassy, open fields and cattle in the vicinity. Ideally, pest control chemicals should not be utilized until all other options have been exhausted and the Horse fly problem has not been resolved. Citronella candles and ultraviolet bug zappers are two common cures for flies and other flying insects when used outdoors. Horse flies are not drawn to rubbish or animal corpses, but keeping your yard as clean of standing water as possible will help to keep them to a minimum (as well as mosquitoes, which are also attracted to standing water!)

Fly Killer Treatments

Products for Pest Control For spot-treatment of Horse flies, use a plant oil-based indoor fly killer such as Maggie’s Farm Home Bug Spray or Maggie’s Farm Flying Insect Killer, which are both highly effective. Plants despise flies and other insects just as much as you do, and the natural oils they create to defend themselves are incredibly powerful in killing and repelling insects of all kinds.

Horse Flies Suddenly Appear In Homes: 3 Reasons Revealed

When it comes to flies, horse flies are the most annoying sort that you may have in your home. Horseflies are both irritating and, for want of a better phrase, potentially hazardous insects. These files do not appear on a consistent basis throughout the year. Horse flies, on the other hand, can unexpectedly emerge in homes at any time of year. So, what causes horse flies to arrive all of a sudden? When do horse flies begin to appear? And what is the root reason of this occurrence? These are the kind of queries that will be answered by this guide.

Plus, there’s a whole lot more!

What Are Horse Flies – An Introduction

The horse fly is the only fly that looks like a housefly and bites hard, yet it is also the most dangerous. Equine flies are one of the most violent kinds of fly, possessing razor-sharp mouthparts that can tear into the flesh of humans and animals. They also migrate in swarms and groups, which is unusual for them. You don’t want to get in their way, therefore avoid doing so. Horseflies are active from late spring to late summer, with the peak season occurring in late July. If you live in a barn or on a farm where there are animals and livestock, horse flies are nothing new to you.

  • Horseflies are able to feed on the blood of any mammal they come into contact with.
  • Horse flies strike campers and hikers who camp or station near rivers or lakes, causing them to suffer from itchy bites.
  • A fully fledged adult horse fly can grow to be up to 1.25 inches in length when completely developed.
  • Their eyes are likewise huge and appear to be violet in color.
  • When the antennas are motionless, you may have difficulty identifying them.

Horse Fly Bite

Insects that bite humans and animals, horseflies have a sharp blade-like mouth that can rip apart the flesh of humans and animals. Horseflies are parasites that feed on the blood of animals, such as the cattle on your farm or in your barn. Horseflies track down their prey by sensing the carbon dioxide that they emit as they fly around. Horse flies are attracted to dark and bright moving objects, according to scientific evidence. Horseflies are attracted to cattle and horses by certain compounds.

  1. The female horse flies bite both humans and animals, which is an intriguing thing to note.
  2. The male horseflies do not attack humans or animals, unlike their female counterparts.
  3. Female horse flies require large amounts of blood in order to create eggs.
  4. Horsefly bites are quite unpleasant.
  5. If the bite area is not treated immediately, it may potentially get infected with pus.

In light of this information, it is evident that horse flies can bite you and your cattle if you reside in an area where horse flies are prevalent. But why do horse flies suddenly emerge in people’s homes? The next section provides an answer to the question.

The 3 Reasons For Sudden Appearance Of Horse Flies In Homes

The following are the three most likely causes of the unexpected emergence of horse flies in your home:

  1. It appears that you have cattle on your land. Your home has a strong ammonia odor that permeates the air. Horse flies are being bred on your land as a result of your actions.

Let’s take a look at each of them individually. Horseflies are not the same as house flies, which are attracted to garbage in houses and yards and feed on it. They’re flies that feed on human blood. In addition, they obtain their blood meals from humans and animals that are found in the natural environment. Horse flies, on the other hand, may make their way into your home. And this is especially true during the warmer months. So, how can horse flies gain access to your home? The most common way for horseflies to enter a home is through open doors and windows, especially if you have items in and around your home that they find appealing.

  • In addition, the water that is discharged from your home’s air conditioner contains ammonia.
  • Horse flies will enter your home if they detect the aroma of ammonia, and they will do so through open doors and windows, as well as through any holes and openings that they may discover.
  • In addition to compost piles and decaying organic materials such as wood and leaves, female horse flies will lay eggs along pond edges or swimming pools, and even within termite mounds.
  • Horse fly larvae prey on small invertebrates and, in rare occasions, frogs as well as other invertebrates.
  • So, what is the best way to get rid of horse flies?
  • Let’s find out what it is.

How To Get Rid Of Horse Flies In Your Home And Property?

The removal of horse flies is accomplished in three stages: examination, treatment, and prevention. Let’s take a look at each of these steps one by one. In order to complete these procedures, however, you must first put on PPE (Personal Protective Equipment). Horse flies will not be able to bite you if you wear this.

Examination or Inspecting For Horse Flies

The degree of the infestation and the location of the infestation’s source will be determined in this stage. That would need an investigation into the sources of horse flies on your land. Horse flies can be found in areas adjacent to your livestock’s housing quarters, so look for them. Check for horse flies in the areas where you store manure, where your livestock eats, compost piles, around pools, ponds, and pastures, and in the areas where your livestock grazes. This will assist you in determining the extent of their infestation as well as the precise time of day when they are most active in your area.

Additionally, you’ll find a large number of grubs around any aquatic vegetation, such as bushes and shrubs, that are developing around your swimming pool or pond. Horse flies have been spotted in the following locations: After that, you can proceed to the following phase, which is therapy.

Treat Your Property To Get Rid Of Horse Flies

The following are the items that you will want in order to get rid of horse flies:

  1. IGR (Insect Growth Regulator)
  2. Disposable Flytraps
  3. Equine spray for animals
  4. Outdoor Insecticide Spray

Now, follow the six methods outlined above to utilize the supplies listed above to get rid of horse flies.

Activate The Fly Trap And Keep It In Places Where You’ve Spotted Horse Flies

Theflytrapis an excellent non-toxic method of capturing horse flies. Remove the plastic seal off the top of the trap in order to activate it. When you open the seal, you’ll see a tab on the side. Pulling the tab will cause it to shatter. After that, fill the trap with water until it is completely full. The flytrap will be activated as a result of this. You’d need to set up many fly traps in different locations where you’ve observed horse flies being active. These bags are meant to be thrown away.

Spray The Horse Fly Repellent Spray On Your Livestock

It is important to take this measure to protect your cattle from the damage and wounds that horse flies can bring to them. Make sure your cattle is clean. Take care to ensure that your cattle is free of filth and dust. Then spray the horse flies repellent spray directly onto the skin of the cattle. Caution: Do not spray the horse fly repellent spray directly into the eyes or nostrils of the cattle.

Mix Insecticide And IGR In A Spray Bottle

It’s time to go on the attack against horse flies on your property, and here’s how. In a gallon of water, combine 4 teaspoons of pesticide and 4 mL of IGR (Insect Growth Regulator) to create a solution. An amount equal to one gallon of the combination is suitable for a 1000-square-foot area. You’d need to create more of this mixture if you’re covering a huge area. Alternatively, you can use the services of a pest control specialist to do a fogging treatment. Stir the ingredients together thoroughly before pouring them into the pesticide spray container.

  1. Spray it on the windows, doors, mulch beds, and the area surrounding your home’s foundation to protect it from the elements.
  2. It is an insecticide that will kill adult horse flies, and it is known as flex 10-10.
  3. Horse flies may be controlled inside your home by using any indoor pesticide spray on them.
  4. The ammonia in the water from your appliances attracts horse flies to your home, causing them to infest your home.

Prevention Of Horse Fly Infestation In The Future

Now that you’ve done your part to rid your property of horse flies, it’s time to make certain that they don’t return. It is important to follow the preventative approach to guarantee that you and your cattle do not receive any further horse fly bites. In addition, the likelihood of horse flies suddenly appearing within you in the future is essentially negligible. And the quickest and most effective method to do so is to use granular fly bait along the perimeter of your property and around the foundation of your home.

Painting the border of your land and the perimeter of your barn, where you keep your cattle, is something you should do.

Fill a bowl halfway with water and add the granular fly bait.

Take a paintbrush and paint the barn walls, fences, and the foundation of your home with the color.

Horse flies will be discouraged from infiltrating your home and barn and attacking you and your livestock as a result of the paint. Horse flies may be controlled with a number of extremely efficient preventative techniques.

  1. Incorporating fine-mesh window screens into your home’s design helps keep out any insects, including horseflies. Fill up any gaps and cracks in your barn’s walls, doors, and windows, as well as those in your home. This will help prevent the horse flies from infiltrating your barn and home. Make certain that the areas where you store and prepare the manure are constantly covered with a tight-fitting lid. Don’t allow cattle waste to accumulate in one location or to be dispersed over your land for several days. Make sure that your property has suitable garbage disposal. Don’t allow organic waste build up in areas where you feed your cattle or horses
  2. Instead, compost it. The area where you store your animal feed should be free of clutter. Do not allow greenery and organic wastes such as decaying wood piles to accumulate on your property for days at a time. Excessive moisture in your home may be avoided by not overwatering it and not allowing it to become stagnant.

Are Horse Flies Territorial?

Horseflies have a strong sense of belonging. If you happen to stroll through one of their hiding or nesting areas, they may attack you.

Are Horse Flies Venomous?

They aren’t, at least not to a human. However, they are capable of transmitting swamp fever to horses, which can be fatal to them.

Are Horse Flies Attracted To Water?

Horse flies are drawn to water, to be sure. As a result, they like to reside in or near aquatic environments such as lakes and ponds. Horse flies have been seen to establish eggs around swimming pools in residential areas.

Are Horse Flies Attracted To Light?

Animals such as horseflies are drawn to linearly polarized light, which is light reflected back to the source. In order to detect water, they must first take up any reflected light from the water’s surface.

Is Horse Flies Aggressive And Dangerous?

Horse flies are indeed aggressive flies, and they may be deadly as well. They have the ability to cut into the skin of animals and humans in order to ingest their blood.

Can Horse Flies Bite?

Horse flies do, in fact, bite. In order to rip apart the skin of its prey, horse flies have blade-like mouthparts that are used to pierce the skin.

Do Horse Flies Sting?

Horse flies do not sting, in contrast to other types of stinging bees. They take a bite out of you.

When Do Horse Flies Go Away?

Horseflies are a nuisance throughout the warm months. By the beginning of the fall season, their numbers had begun to decline significantly.

Are Deer Flies And Horse Flies The Same Thing?

They are not, in fact. Horse flies and deer flies have considerable variances in their behavior and appearance. Horse flies are smaller in size than deer flies. Furthermore, when deer flies are immobile, their wings are spread widely apart, giving them the appearance of a moth rather than a fly. Horse flies, on the other hand, do not have brownish-yellow straps on their abdomens, which are present in deer flies. The abdomen of horse flies is dark in color. The Deer Fly However, both deer flies and horse flies bite by cutting the skin with their scissor-like mouthparts, which is similar to that of a mosquito.

Skin ulcers, a high temperature, and a headache are all indications of rabbit fever.


There are three possible explanations for the unexpected development of horse flies in homes:

  1. It appears that you have cattle on your land. Your home has a strong ammonia odor that permeates the air. Horse flies are able to reproduce on your land because of your actions.

Horseflies become active throughout the summer months, and their bites are harmful for both humans and animals. It has been explained in this tutorial why you get horse flies bites and how to get rid of horse flies on your property if you have them. Also included in this section is a list of preventive actions that you may do right away to avoid a horse fly infestation on your property in the near future. Keep in mind that horse flies must feed on the blood of you and your cattle in order to survive.

Horse Flies: Control, Bites, & Extermination of Flies

Adult horse flies are fast, powerful flyers, capable of flying for more than 30 miles and dispersing widely, yet they are not widely dispersed. They are most frequently attracted to moving and dark items. When horses fly, they tend to congregate on routes and roads, particularly in forested areas, where they await possible hosts. Horse flies are drawn to light and will swarm around windows from time to time.


Horse flies are generally found in or near woodlands or forests. Species are best visible when they are feeding in broad daylight, which is most often on windless, hot, bright days. On general, larvae grow in moist soil near sources of water, but this might vary.


The nectar of adult horse flies is their primary source of nutrition, but females require a blood meal in order to breed properly. Bites from female horse flies, especially those from large specimens, may be quite painful since their mouthparts are employed for ripping and lapping, as opposed to bites from mosquitoes, which just pierce the skin and sucking blood. In addition, female horse flies are quite persistent, and they will often continue biting a host until they are successful in obtaining their blood meal or are killed.

Some species are disease organism carriers, however in the United States, the majority of horse fly-vectored illnesses affect only cattle, not humans.

Where Do Horse Flies Come From?

It’s possible that you won’t have to deal with horseflies for the most of the year. Horseflies will not cause much of a nuisance for you the most of the time. They mostly feed on nectar and play a role in the pollination of flowering plants. When it comes time for them to reproduce, you will begin to see their vampire inclinations. They begin to look for blood, and much like mosquitoes, a female horse fly requires blood in order to properly lay eggs, which may number anywhere from 25 and 1000 in number.

  • The majority of their attacks are carried out in a group.
  • Understanding what motivates them to attack might assist you in putting control measures in place that are effective.
  • It’s not just their heads that are big; it’s also their eyes.
  • When they puncture the skin of mammals, they utilize razor-sharp mouthparts to extract blood from the wound they have made on the animals.
  • Anthrax, anaplasmosis, Lyme disease, and anthrax are only a few of the illnesses conveyed by horse flies, which also spread hog cholera and other diseases such as filariasis and tularemia, among others.
  • This is a period of year when you will enjoy more bright days without as much wind as usual.
  • They only eat throughout the day and do not eat in the evening.

Their activity is at its peak in August since it is during this month that they are able to reproduce.

See more information about Horse FliesMoisture In order for horse flies larvae to develop, they require damp, muddy environments.

When applying near water, make certain to use the proper products.

What is it that they are drawn to?

For the use of swimming pools.

Because of the presence of carbon dioxide in the water, swimming pool water is also black and heated.

They are drawn to huge moving items, like as horses and humans, and they prefer dark objects over light ones in their environment.

Horseflies are widely believed to be uncontrollable by the majority of people.

Horse fly repellents and horse fly spray are available for purchase.

If you have horses that graze, make sure that they remain indoors during the day and are allowed to go out to graze during the evening. This is due to the fact that horse flies are more likely to attack during the day than at night. Additionally, try using alternative horse fly control solutions.

Horse Fly and Deer Fly are two types of flies. Horse flies and deer flies are both bloodsucking insects that may be a major annoyance to cattle, horses, and people. Horse flies and deer flies are both considered to be a serious pest to humans. Horse flies are around 3/4 to 1-1/4 inches in length and have transparent or strongly colored wings, as well as brilliantly colored eyes, in most cases. Deer flies, which are smaller than horse flies and regularly bite humans, have dark bands across their wings and colored eyes that are similar to those of horse flies.

  • The quantity of flies and the severity of their onslaught varies from one year to the next, depending on the season.
  • It is possible that animals will harm themselves when fleeing from the insects.
  • For their meal, Webb and Wells projected that horse flies would drink 1 cc of blood and that 20 to 30 flies dining for 6 hours would consume 20 tablespoons of blood, according to a USDA Bulletin 1218.
  • Flies such as horse flies and deer flies are more active during the daytime hours.
  • Once they have taken up residence on a host, they slit the skin with their knife-like mouthparts and feed on the blood pool that has formed.
  • The soreness and swelling caused by bites normally subside within a few days.
  • Bites may be painful, and general first aid-type skin lotions can assist to alleviate the discomfort.
  • In terms of animal pests, male flies are of no significance because they feed on nectar.
  • The fly’s painful bites usually provoke a response from the victim, and the fly is compelled to move on to another host as a result.

It is the muck around the borders of ponds and streams, as well as marshes and seepage sites, where horse fly and deer fly larvae grow and mature. Some are aquatic, while others grow in soil that is rather dry. Females lay batches of 25 to 1,000 eggs on vegetation that grows over water or in moist areas, depending on the species. They descend to the ground and feed on decaying organic debris as well as tiny creatures in the soil or water, which they acquire via this process.

The larval stage, which can last anywhere from one to three years depending on the species, is the most common. In order to pupate and eventually emerge as adults, mature larvae must crawl to drier locations.


During the summer, deer flies are generally only active for brief periods of time at a time. Repellents such as Deet and Off (N-diethyl-metatoluamide) can give up to several hours of protection when used outside. Follow the directions on the label since some people might develop allergies after using a product for a long period of time. Also, check for age limitations. Permethrin-based repellents are intended for use on clothes alone, however they often give a longer duration of protection than other repellents.

Even after a remedy has been administered, these flies will continue to swarm and annoy you.

Hats with mesh face and neck veils, as well as neckerchiefs, may provide some protection under severe circumstances.


Horse flies and deer flies may be a real annoyance when they congregate near swimming pools. They may be drawn to the water by the gleaming surface or by the movement of the swimmers in the water. There are currently no viable recommendations for addressing this issue. Permethrin-based sprays are approved for use on animals and horses, according to the label. Because these pesticides are extremely unpleasant to the flies, they are forced to flee nearly soon after landing on the surface. Frequently, the flies do not come into touch with the pesticide for long enough to be killed, and as a result, they continue to be an irritation.

It is possible that repeated applications will be required.

In addition, pyrethrin sprays are effective, although their effectiveness does not continue as long as permethrin.

In the daytime, if animals have access to shelter, they will be able to avoid the relentless onslaught of these vexing pests.


It is extremely difficult to detect and/or destroy the breeding sites of horse flies and deer flies, and it is nearly impossible to do so. The fact that they spawn in environmentally sensitive wetlands raises concerns about the implications of drainage or pesticide treatment on non-target creatures or water supplies. Furthermore, these insects are excellent flyers and have the ability to move in from a distance. Breeding sites may be quite large or located a long distance distant from the location where the issues are occurring.

Some changes in behavior or the use of repellents may be necessary to allow for enjoyment of the outdoors.

Horse Fly

Common Name Horse Fly
Scientific Name Tabanus sp.(Diptera: Tabanidae)
Size 2/3 inches long
Colour Yellow-white to pinkish thick, tough skin
  • Unlike honey bees, adult flies are dark and hairy, strong, and approximately 2/3-inch long, visually resembling them except for the fact that they have only one pair of wings instead of two. The horse bot fly’s wings have slight smoky patches on them, similar to those of a bat. Fully-grown larvae (maggots) are up to 2/3 inch long and have thick, tough skin that ranges from yellow-white to pinkish in color. A pair of powerful, hook-like mouthparts are present on one end (the rear) and a blunt end (the front) on the other (the front). A ring of strongspines surrounds each segment of the body. Several additional species of bot flies are seen on horses, including the chin flyorthroat bot fly, Gasterophilus nasalis(Linnaeus), and the lipornose bot fly, Gasterophilus haemorrhoidalis(Linnaeus) and the lipornose bot fly, Gasterophilus haemorrhoidalis(Linnaeus). Horse flies are distinguished in part by the form of their eggs
  • They eat by sucking blood and may produce a painful and severe bite if they bite the victim. These flying pests are closely related to Deer flies in both appearance and behavior. Horse flies are similar in appearance to Deer flies, but are slightly bigger in size. A dark pattern can be seen on the wings of this fly, and its body can be either brown or black in color. The female of the species feeds on animal blood, while the male of the species is a pollen collector. Horse flies lay their eggs in marshy places near bays, lakes, ponds, and swamps, where they hatch into adult flies. These flies have larvae that feed on insects and may be seen growing in wetlands
  • The female of the species feeds on animal blood, while the male of the species is a pollen collector. Horse flies lay their eggs in marshy places near bays, lakes, ponds, and swamps, where they hatch into adult flies. Insect-eating larvae of this fly can be seen growing in wetlands where they feed on insects.
  • The majority of horse flies and deer flies may be found in brushy or low-lying pasture regions near creeks, streams, or tanks that offer enough moisture for the development of the juvenile stages. Magnagogues have mouth hooks that tear tissue in the digestive systems
  • Adults do not have mouthparts that are capable of tearing tissue. Horses, mules, and donkeys are the most common hosts. In their attempt to lay eggs on hostanimals, adult female flies force horses to run and defend themselves against fly “attacks” (hovering, buzzing, and hitting), which can result in harm in some cases. Larvae dwell in the digestive tract, where they cause damage to the tongue, lips, stomach lining, and intestines, among other things. Apparently, they get their energy from the inflammatory chemicals released by the host in response to their presence. Infestations result in mechanical harm to the host animal as well as an infected ulcerous condition that causes the host animal to starve.
  • This species’ larvae grow in the digestive systems of host animals throughout the winter months. Host excrement is contaminated with full-grown larvae that are discovered in the late winter and early spring months. Once they have reached this stage (instar), they burrow into the earth and construct a puparium out of the larval skin from their previous stage. It takes 3 to 10 weeks for them to develop into adult flies within the puparium
  • Adults are active from mid-summer until the end of the summer season. Female horses glue eggs to their coats, notably the coats of their front legs, but also the coats of their belly, shoulders, and rear legs, according to adult females. Depending on the appropriate stimulation (moisture, heat, and friction) provided by the horse licking or chewing egg-infested hair, eggs can hatch in 10 to 140 days. The larvae of the first stage (instar) enter the mouth and burrow into the tongue for around 28 days before molting and traveling to the stomach, where they remain for 9 to 10 months, growing into the third stage after approximately 5 weeks of development. Every year, there is a new generation.
  • In addition, they are major vectors of illnesses such as leucocytozoa and turkey sickness.
  • Adult horse fly and deer fly larvae are very ferocious biters. They cause animals to lose weight and have the potential to spread illnesses such as anaplasmosis, anthrax, and others.
  • Because of the nature of this fly, it is hard to completely remove it by spraying operations. The Advantage Fly Trap is the only trap that has had any success with biting flies (such as the Horse fly and the Stable fly). However, the success has been limited in the past. In certain circumstances, the revolutionary technology of this product allows us to attract and trap blood-sucking flies for the first time, which is a first in the industry. Yet, the results vary depending on the species and location
  • However, this trap may capture a wide variety of flies. If Horse Flies are discovered within a building, make sure that all probable access routes have been removed. They will not be discovered reproducing indoors in the same way that a house fly would be. The most effective method of controlling flies is to eliminate all available breeding grounds and food sources. As evidenced by the horse fly’s biology, this form of fly control is nearly impossible with this particular species.


Greetings, BugFans! If you’re looking for insects, the first guideline is to look on flowers. Flowers give a place to relax, as well as a place to eat and be eaten by other animals and people. The second guideline is that if you find an insect that is extremely motionless (or in an unusual posture), you should seek for a predator nearby. Consequently, when the BugLady noticed a horizontal horse fly, she realized that something was up, and she was able to quickly detect the ambush bug above and to the left of the fly (the presence of the fly’s eyes was an added benefit).

  • Even though it’s a group we despise, December is a good time to think about them intellectually rather than emotionally.
  • When horse and deer flies buzz on approach (the whining of the deer flies is higher-pitched), one source reported that horse flies prefer exposed flesh below the knees, while deer flies prefer the back of your neck.
  • “Bulldog Flies,” “Clegs,” “Yellow Flies of the Dismal Swamp,” “Greenheads,” “Gad Flies,” and “Copper Heads” are some of the vernacular names for these flies, according to bugguide.net.
  • There are around 4,500Tabanidspecies worldwide, with 350 of them found in North America.
  • The genusTabanus (pronouncedTa-BAY-nus) contains the horse fly species that we are most familiar with.
  • Due to the fact that their slightly aquatic progeny reside in permanent wet/moist regions, they are most frequently discovered in these areas, however they may be found anywhere from deserts to mountaintops.
  • They feature large, wrap-around eyes that are frequently referred to as “bulging” (male flies have large, wrap-around eyes; female flies have separate eyes).
  • Male horse flies feed on nectar and pollen and do not have the ability to bite since they lack the necessary equipment.

As a result, they attack people on the street, focusing their attention on massive, dark-colored, moving items that emit a cloud of CO2 (including motor vehicles, says Eric Eaton, inThe Kaufman Field Guide to Insects of North America) in the habitats where the BugLady lives, clouds of deer flies surrounding the side mirrors of slow-moving automobiles are a familiar sight in July, especially in the shady areas).

  1. Their mouthparts are described as “a strong stabbing organ with two pairs of sharp cutting blades, and a spongelike component used to lap up the blood that oozes from the wound” by Wikipedia.
  2. A second meal is required by certain females, and it is via biting a second victim that she may spread illnesses (the list of pathogens is short, and human infection is uncommon in Wisconsin).
  3. Horse flies are not without predators – birds prey on both the adults and the larvae of horse flies; nematodes and wasps parasitize the larvae; and solitary wasps catch and devour the adults in order to replenish their egg caches and to feed their young.
  4. Despite the fact that we don’t pay attention to them since we don’t know what they do for a job, we could observe that they’re a quite attractive and diverse group of flies.
  5. along with the fact that they have beautiful blue eyes that macro photographers like, as well as many other characteristics (Why?
  6. She lays her eggs in clumps that can include as many as 1,000 eggs in multiple layers, depending on the size of the clump.
  7. When they hatch, the small larvae are equipped with a spine that aids them in exiting the egg.

They spend their summers there, sometimes for multiple summers at a time, especially in the northern hemisphere, preying on tiny, soft-bodied insects and crustaceans, which they subdue by biting them and injecting venom into them.

(And, like their elders, they’re capable of dishing out quite a bite of their own if not handled with care).

Horse flies, according to Aeschylus, a Greek dramatist who died about 456 BC, were responsible for driving people insane.


Generally speaking, it is a northern species with dispersed populations in the Appalachian Mountains, and it prefers chilly, forested wetlands.

“In recreational areas next to lakes where cattle is not present, this species is believed to represent a major hazard to human life,” according to Jones and Anthony’s Tabanidae of Florida book.

The horse fly Hybomitra illota, with its bullet-shaped body and dark stripe on its abdomen, which is sitting on a wooden boardwalk, is most likely a sturdy small bullet-shaped fly with a dark stripe on its abdomen (mid-America, north).

The male population congregates in huge groupings at “mating regions” when particular meteorological conditions are in place.

Hybomitra illota is a species of Hybomitra that is known to irritate people. However, this is not the case in God’s Country in December. The BugLady is a fictional character created by the author of the novel BugLady.

How to Get Rid of Horse Flies – Facts & Control Techniques

Horse flies are one of the most vicious species of insects on the planet. Horse flies, in contrast to normal house flies, have mouth parts that are capable of cutting and tearing. Horse flies (especially female horse flies) are a nuisance to livestock because they settle on the bodies of cattle and bite them in order to take their blood. In addition, unlike mosquito bites, the horse fly bite is extremely painful. They have jaws that are similar to scissor-like and are capable of tearing flesh.

In order to better understand how to get rid of horse flies, let us first examine their physical characteristics in order to recognize them more readily.

Identifying a Horse Fly:

Horse flies have a yellowish-brown or blackish coloration to their wings and bodies. It is around 20 to 25 mm long, has a large head, and has hairs all over its body. They are remarkably similar to honey bees, with the exception of the fact that they only have one set of wings. The undersides of the wings are coated with subtle smoky patches. The eyes of a Horse fly are exquisitely colored with rich metallic color tones that shimmer in the light. Females have complex eyes that are dichoptic (separated), whereas males have holloptic (continuous) eyes.

  1. Horse flies are most commonly found in low-lying meadows near creeks, streams, and tanks, where they breed and reproduce.
  2. Female species feed on the blood of animals, whilst their male counterparts are pollen gatherers.
  3. Take a look at this article: How Do You Attract Flies Into Your Home Or Surrounding Environment?
  4. Female horse flies require a blood meal before they can lay eggs because it supplies them with the appropriate levels of protein they require to reproduce successfully.
  5. Evolution: Eggs are placed on or under gravels or plants, generally close to a water supply, and hatch after about a month.
  6. Furthermore, at this period, they graze on little insects or responses.

During the larval stage, which can last up to a year, the larvae burrow into the earth and begin the process of pupation. The pupal stage can last anywhere between 6 and 12 days. Adult flies emerge from the puparium around 3-10 weeks after hatching. Damages:

  • Getting bitten by a horse fly is quite unpleasant
  • They are carriers of illnesses such as leucocytozoan
  • They cause animals to lose weight
  • And they cause livestock to die. Horse flies have also been linked to the transmission of illnesses such as anaplasmosis, hog cholera, tularemia, and anthrax, among others.

Few Interesting Facts about Horse Flies:

  • The horse fly is a member of the ‘tabanidae’ family, and it is one of the biggest insects on the planet. Horse flies may be found all over the planet, with the exception of the extreme northern and southern latitudes. Horse flies are found in over 3,000 different species around the world. The female horse fly’s mouth parts have the appearance of saw blades. It makes a hole in the skin in order to feed on the blood that is drained from the wound. Male horse flies do not bite since they do not have biting mouth parts, and as a result, they feed on nectar collected from flowers. It takes a year for a horse fly larva to mature into an adult. In addition, an adult horse fly only lives for a few days. Horseflies are known by a variety of names in different parts of the world
  • For example, in Canada, they are known as “bull dog flies,” while in Australia, they are known as “March flies.”

How to Get Rid of Horse Flies:

Let’s have a look at how to get rid of horse flies now that we’ve learnt so much about them. You may learn how to regulate them in this area, which includes a number of suggestions.

1. Using Disposable Fly Traps:

Horse flies are easily captured with disposable fly traps, which are one of the most effective ways available. Unlike traditional traps, these ones contain an attractant that is triggered by sunshine and water. As soon as the attractant is engaged, it attracts the horse flies to enter the trap, where they are imprisoned after the flies have entered the trap. All you have to do to use these traps is unpack them, add bait/attractant along with a little water, and hang them up. These traps are a safe and effective technique to control horseflies, including those that are pesticide resistant.

Check out this one on Amazon, which has received a lot of excellent feedback.

2. Using a homemade Fly Trap against Horse Flies:

As I previously stated, horse flies are drawn to dark moving things; thus, we will utilize this knowledge to our advantage and construct a trap that will attract horse flies and kill them. To construct this trap, we will need the following materials:

  • A difficult string to work with
  • A medium-sized ball with a dark color and a round shape
  • A fly paper (either commercially available or handmade)
  • A stool, to be precise.

To construct the trap, tie the dark colored ball to the string and secure the free end of the string to the bottom of the stool. After that, wrap the fly paper over the stool’s legs and secure it in place. Once you’ve done that, hang the stool in the area where the horse fly infestation is prevalent. Every few hours, simply press the ball to the point where it begins to sway in the breeze. The horse flies will be attracted to the dark colored ball because of its swinging action. When they approach close to the trap, they attempt to land on it and become entangled in the fly paper.

3. Coke Bottle Trap made with Rotten Meat:

This is a pretty easy trap that has worked for a large number of individuals. So, all you need is the following to do this:

  • A Coca-Cola bottle that has been emptied
  • To cut the bottle, you’ll need a sharp knife or a pair of scissors. Use a drill or any other sharp tool to make some holes in the ground
  • Cellophane tape is a type of adhesive used to seal packages. rotting meat weighing 50-100 grams

To construct this trap, begin by slicing the coke bottle with a knife, as illustrated in the accompanying illustration. Following that, drill a 1 cm hole in the bottle cap in the manner illustrated. After that, place the decaying meat pieces in the lower portion of the bottle with a little water in it. Then, as illustrated, flip the upper section upside down. Cellophane tape is used to ensure that the edges are firmly secured. Place these traps in close proximity to the contaminated area (away from your cattle).

Moreover, once they have entered the bottle, it will be impossible for them to get out on their own.

This is supported by research.

4. Sticky Fly Paper Trap with Odour Baits:

Many individuals have had success in reducing horse flies by employing huge sticky fly traps in conjunction with an attractant or other attractant. It has also been demonstrated that when normal fly paper traps are used in conjunction with scent baits, the effectiveness of the traps rises dramatically.

To make this work, you will first need a large sticky fly paper trap, which you may use in conjunction with smell baits if you choose. You might use any of the following ingredients to make odor baits:

  • The presence of carbon dioxide (CO 2) in bovine breath attracts horse flies, which are drawn to carbon dioxide in general. To attract them, you might use a CO2 cylinder or ‘dry ice’ to catch their attention. However, in order to make this function under real-world field settings, enormous volumes of CO2 gas would be required. Acrylatone (Nail Polish or Varnish Remover)– Acrylatone is also a component of cow breath, which means that many species of horse flies are drawn to this liquid to a substantial degree. One of the constituents of cattle sweat, octen-3-ol, is a fly attractant to a modest amount. It is a component of human sweat, as well as a component of cow sweat. Due to the fact that octenol is a highly expensive chemical, it is exclusively employed in laboratory research against horse flies
  • However, this is changing. Ammonia (NH3 vapour)– Ammonia is a component of bovine urine, and it has been seen to attract some species of tabanids
  • It is also a component of feces. It was cow urine that was discovered to attract horseflies, and it had to be matured for at least a week before it could be used. Furthermore, because it is readily available and very simple to administer, it is a popular attractant, particularly among cattle ranchers.

5. Umbrella Type Horse Fly Trap:

The use of an umbrella trap has been shown to be extremely effective against horse flies. You will need the following items to complete this project:

  • Sheets of plastic sheeting or plastic screening (four sheets) 5 feet in length and 4 feet in width
  • A stapler or a glue stick A pole that is 5 or 6 feet in length
  • A jar made of plastic
  • A black plastic or rubber ball with a diameter ranging from 16 to 20 inches

The four pieces of plastic sheeting should be joined together using stitching or staples to form a pyramid shape, as indicated in the figure below. The pyramid should be around 4 feet high and 3 feet broad along each of its four bases, depending on the size of the materials used. Following that, a ring should be placed to each bottom corner of the trap in order to attach guy lines that keep the trap in place. After that, join the 6 foot pole in the center of the pyramid along with the rest of the pyramid.

  1. It is important that after the trap is properly assembled, the ball should rest slightly below the plastic sheets.
  2. Fix the jar lid upside down and use a 2 inch hole punch to make a 2 inch hole in both the lid and the cardboard plate.
  3. This jar will be used to collect flies, which will be placed inside.
  4. After that, secure the guy lines to some supporting poles so that they may act as tent ropes to hold the canopy in place.

6. Manning Trap for Horse Flies:

The Manning trap operates on the same principle, namely, luring flies with a dark moving item and then catching them in a container after they are attracted. A conventional manned trap looks much like the one seen above. Please keep in mind that there are many various methods to design a manned trap, and I have just illustrated the most basic one here for illustration purposes. In addition to manning traps, horse buddy traps and H-Traps are modified versions of the manning trap. To construct a manning trap, you would need the following materials:

  • The following items: a tripod stand or sufficient wood to construct your own stand
  • A sheet of plastic or a fabric
  • An opaque ball of black color
  • A little funnel
  • A piece of string
  • A bottle of anything

First and foremost, if you don’t already have one, construct a tripod stand of 5 feet in length. After that, drill a 3 – 5 cm hole into the top of the tripod and screw the funnel into place over the hole. Afterwards, attach the bottle to this in the manner depicted in the figure above. To attach the bottle to the funnel, you can use cellophane tape if necessary; however, make sure the bottle is securely fastened to the funnel before proceeding. The dark colored ball should be connected to the string, which should be tied to the bottom of the tripod so that it hangs at least 2 feet over the tripod legs.

Plastic sheet or fabric should be used to cover the top three feet of the stand. As a result of this, you should maintain the trap close to the contaminated region and you should soon see that the bottle is full with dead horseflies. Check out this H – Trap that is available on Amazon.

7. Homemade Repellents for Horse Flies:

Several natural oils have been shown to repel horseflies, and you might use them to make a repellant for yourself or your pets if you know what you’re doing. Repellent number one: To produce this repellant, combine the ingredients in the following order and keep them in a container.

  • 1-1/2-cup Avon Skin So Soft (Bath oil)
  • 1/2-cup water
  • 1/2-tablespoon eucalyptus oil
  • 1 cup white vinegar

You may apply the repellant straight to the skin of your dogs if you so desired. Please with your veterinarian before using this product. Repellent number two: To produce this repellant, combine the ingredients in the following order and keep them in a container.

  • Light mineral oil, 1/4 cup lemon juice, 1 teaspoon citronella oil, 1 teaspoon eucalyptus essential oil, and 1 teaspoon lemon dish soap are all you need.

You may apply the repellant straight to the skin of your dogs if you so desired. Please with your veterinarian before using this product. Repellent number three: To produce this repellant, combine the ingredients in the following order and keep them in a container.

  • 3 components: 1 part lavender oil, 2 parts water, 2 parts rubbing alcohol

You may apply the repellant straight to the skin of your dogs if you so desired. Please with your veterinarian before using this product. Read this article for more information: Natural oils to repel flies.

8. Using Insecticides:

Although it is theoretically feasible to kill horse fly larvae using pesticides, doing so would result in the water being harmful or contaminated due to the fact that they reside near streams or rivers. As a result, treating them when they are in the larval stage is very impossible. Field experiments, on the other hand, have demonstrated that daily treatment of cattle with a naturally occurring pesticide known as’synergized pyrethrins’reduces the bite rates by horse flies while having no negative effects on the cattle themselves.

Concentrated pyrethrins pesticide may be purchased from any farm supply or agricultural chemical company.

For example, if you want to treat horses, you should choose a formulation that has been labeled particularly for this kind of animal.

However, by spraying it on every other day, it is possible to attain some kind of control.

9. Using Dish Soap and Vinegar Spray to kill Horse Flies:

When it comes to flies, dish soap is quite efficient against most breeds, including horse flies. It is beneficial to use a dish soap that contains borax, which is an insecticide; the greatest thing about using a dish detergent that contains borax is that it has no negative effects on you or your animals. For a dish soap spray, take an empty spray bottle and fill it with 4 teaspoons dish soap, 2 cups white vinegar, and 1 cup warm water, shaking the entire time. Your dish soap spray is now complete.

10. Commercially available Horse Fly Repellents:

I’ve seen numerous products that claim to be effective against horse flies, but the most of them are ineffective.

However, there are a few products that are very effective in combating them. These are the products:

  • Rtu Equisect Botanical Fly Repellent Rtu Spray– This is a natural fly spray that repels 5 different types of flies, including horse flies. It is available in a variety of scents. Check out the book on Amazon
  • Pyranha Wipe N Spray– This insect repellent includes pyrethrin (which is believed to be the safest pesticide available) and is effective against horse flies and other biting insects. Check out the book on Amazon

Please remember to consult your veterinarian before using any of these items. Read this article for more information: Natural oils to repel flies.

Prevention Tips against Horse Flies:

  • Maintain the cleanliness of your animals. Maintain a clean barn at least twice a week by cleaning out the waste and spilt feed. Aside from that, you might apply pesticides on the dung heaps, which would prevent the larvae from forming. Ensure that there is no standing water in the shed and that you have a sufficient drainage system in place so that there is no stagnant water where the horse flies may lay their eggs. It is necessary to trim the grass and weeds in order to make the environment unsuitable for horse flies. The use of a strong fan in animal sheds can greatly reduce the number of horse flies that enter the facility. Use ear nets, face masks, and repellant tags on your animals to protect them from predators. On Amazon, you may get face masks with ear nets
  • They are reasonably priced.

Horse Fly Bite Symptoms:

Horse fly bites are quite uncomfortable. The following is a list of signs and symptoms that might help you determine if a wound is caused by a horsefly bite or not:

  • A horsefly bite results in thick, red skin that is difficult to remove. Itchy skin accompanied with pain
  • Early signs and symptoms of bacterial infections
  • Sometimes the skin remains red and inflamed for several days after the incident. Some people may develop a skin rash, hives, or wheezing as a result of the allergy
  • Others may not. Swelling around the eyes and lips is another symptom that some people encounter.

How to Treat a Horse Fly Bite:

It is extremely vital to treat a horsefly bite as soon as possible. To cure a bite, follow the instructions outlined below: Disinfect the area: To begin, thoroughly wash the area with soap and water to remove any remaining contaminants. You might also use a disinfectant that is based on alcohol or vinegar. If you are outside and unable to sterilize the area at that moment, cover the wound with saliva until you can disinfect the region. Saliva includes the protein Histatin, which has healing properties, and this will help you to heal the bite until you can get indoors and properly treat the situation.

Medications for Allergies: If the itch is becoming intolerable, you might try using a hydrocortisone cream directly to the wound.

Monitor the Wound: Keep an eye on the wound since there is a potential that it can get infected with germs.

So that was the end of it.

Also, I’d be interested in knowing if you have any other top-secret strategies for getting rid of horse flies.
