The Horse Fly Life Cycle Female Horse flies lay their eggs under gravel or vegetation, within some proximity to a water source. When the eggs hatch, the whitish, spindly larvae move into the nearby water or damp soil, during which time they feed on small insects and even reptiles.

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

Horseflies – as well as their cousins, the deer fly and the yellow fly – are dreaded pests, especially during the summer months, when they are active during the mating season of other insects. Despite the fact that only the female flies of each species consume blood, the bites of the huge insects are unpleasant and can result in rashes and mild illnesses. The fact that it is difficult to control the horse fly population and their biting means that the most effective way of minimizing horse fly bites is simply to understand what attracts the insects: knowing this information can mean the difference between a pleasant day at the waterside and a miserable run back to the car.

TL;DR (Too Long; Didn’t Read)

During the summer months of July and August, only the female horse fly consumes blood; this is due to the fact that female horse flies require blood from a vertebral mammal in order to give birth to their young. Male horseflies and female fly on the prowl for food absorb only the nectar of plants.

The flies prefer to hunt in cold, moist regions near water and soft soil whenever feasible, since this provides the best conditions for depositing eggs. Maintaining a presence in dry, sunny locations might reduce the likelihood of meeting horseflies as a result of this.

Bloody Attractions

The female horse fly has a variety of methods for identifying prospective food sources, including: The flies are able to distinguish between CO2 emissions and body odor, and they will go for the sources of both. Aside from these typical sources of CO2 and body odor, horseflies are also drawn to quick movement and body heat, both of which are conducive to their attraction. Flies are also drawn to wood smoke and dark hues, in addition to the previously mentioned factors. During the summer, colors such as blue and green in particular tend to be quite enticing to horse flies, and so should be avoided while heading to waterside places.

Horse Fly Trap and Control Methods

Unfortunately, there are few effective strategies for controlling horse flies and reducing their biting. Although it is possible to reduce the danger of bites, there are currently no recognized techniques for completely eliminating the risk. Horseflies are resistant to the majority of insect repellents, while DEET and other comparable repellents can help to keep the insects at bay. Horse fly traps are available, however their efficiency varies from one manufacturer to the next. The traps are made out of a giant, dark-colored sphere that is designed to move back and forth, and they are sometimes sprayed with some form of animal musk or other enticing aroma to entice the prey.

It might also be beneficial to drain any standing pools of water around the property to reduce the likelihood of horse fly infestations.

Facts About 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.

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 are also distinguished by their huge, brightly colored eyes.

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.

See also:  What Do Horse Flies Eat?

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 and Deer Flies

|Download the PDF version of ENTFACT-511: Horse Flies and Deer Flies.

by Lee Townsend, Extension EntomologistUniversity of Kentucky College of Agriculture

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.

  1. The quantity of flies and the severity of their onslaught varies from one year to the next, depending on the season.
  2. It is possible that animals will harm themselves when fleeing from the insects.
  3. 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.
  4. Flies such as horse flies and deer flies are more active during the daytime hours.
  5. 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.
  6. The soreness and swelling caused by bites normally subside within a few days.
  7. Bites may be painful, and general first aid-type skin lotions can assist to alleviate the discomfort.
  8. In terms of animal pests, male flies are of no significance because they feed on nectar.
  9. 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 locate and/or eliminate the breeding sites of horse flies and deer flies, and it is nearly impossible to do so. They breed in environmentally sensitive wetlands so effects of drainage or insecticide application on non-target organisms or water supplies is a concern. Also, these insects are powerful flyers that can move in from some distance out. Breeding sites may be very extensive or some distance away from where problems are occurring. Fortunately, horse flies and deer flies are sporadic problems for specific times of the year.

What Attracts Horse Flies?

Are you curious about what attracts the biting horse fly? Deer flies and yellow flies are cousins of the horse fly, as are other types of insects. The majority of their mating occurs during the summer months. Female horse flies are well-known for sucking blood from their victims. Their bites are quite painful, and they put you at danger of having rashes and infections as a result of them. Horseflies are notoriously difficult to manage due to their high population and irregular biting habits. One of the most effective methods to deal with a horse fly is to figure out what attracts it in the first place.

Biting, Birth, and Eating

In terms of sucking blood, this is solely linked to a female horse fly, according to the literature. In most cases, Horse Flies are most active during the months of June and August. The reason for this is that the females require blood in order to deposit their eggs, which can range in quantity from 25 to 1000 in total.

Horse flies are only interested in plant nectar when they are male. Horse flies are most commonly seen hunting in locations that are surrounded by water and where the ground is soft, such as marshes. An ideal setting for ahorsefly to deposit its eggs is provided by this habitat. Horseflies are most active during heatwaves and bright days. They will not only attack people, but also most other animals, such as horses.

Bloody Attractions

Female horse flies are frequently equipped with a variety of ways for identifying potential food sources. They have the capability of detecting CO2 emissions as well as the odor of the human body. They utilize these signals to pinpoint the locations of their origins. On the other hand, they are attracted to quick movement and body heat, both of which are sources of attraction for them. You will also notice that they are drawn to dark hues as well as the smell of wood smoke. It has been observed that the color blue appears to be particularly appealing to the horse fly.

  1. Blue is a hue that attracts water.
  2. As a result, it is highly suggested that you wear caps, long sleeves, and other protective clothing to keep yourself safe.
  3. In order to live, the larvae require wet soil.
  4. It will then be possible for the horsefly larvae to feed on organic detritus, snails, and many other insects.

Controlling horseflies

Fortunately, there are a variety of horsefly control products and methods that may be used to assist combat these pesky insects. Despite the fact that there are just a handful of these ways, they can assist to reduce their bites. At this time, there are no well-established procedures for completely removing them.

There are some fascinating proposals for creating a DIY horse fly trap, and you should look into them. It may be a perfect answer for the summer months when they are at their most active, which is when they are most prevalent.

Reader Interactions

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.

  1. Horseflies are able to feed on the blood of any mammal they come into contact with.
  2. Horse flies strike campers and hikers who camp or station near rivers or lakes, causing them to suffer from itchy bites.
  3. A fully fledged adult horse fly can grow to be up to 1.25 inches in length when completely developed.
  4. Their eyes are likewise huge and appear to be violet in color.
  5. 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.

  • Spray it on the windows, doors, mulch beds, and the area surrounding your home’s foundation to protect it from the elements.
  • It is an insecticide that will kill adult horse flies, and it is known as flex 10-10.
  • Horse flies may be controlled inside your home by using any indoor pesticide spray on them.
  • 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.

What Attracts Horseflies?

Photographs courtesy of IHemera Technologies/PhotoObjects.net/Getty Images Keep in mind that the phrase “horsefly” is a misnomer. Cattle, dogs, and even humans can be the victims of a female horsefly’s unpleasant bite, which can be quite painful. Using its razor-sharp mouth parts, the horsefly (genus Tabanus) cuts a gash in the skin and then feeds on the blood that comes out. A component of the horsefly’s saliva functions as an anti-clotting agent, allowing the fly to feed on the blood of his warm-blooded victims more quickly than it would otherwise.

Breeding Environment

For breeding, the huge, heavy-bodied horsefly is drawn to marshy places and moist, low-lying meadows, where it may lay its eggs. The fly lay their eggs in swarms on leaves or other vegetation that hangs over bodies of water, and then die. When the eggs hatch, the larvae are able to dig deep into the soft, damp soil, where they feed on organic garbage, snails, and other insects, as well as on the soil’s moisture. Given that the horsefly’s larvae require damp soil to live, the horsefly has a special predilection for breeding grounds that are moist.

If you live near a wetland, this implies that there is nothing you can do to reduce the attractiveness of mosquitoes.


In order for horseflies to thrive, they require hot, bright conditions with little to no breeze. While there is little you can do to influence the weather, you can reduce your and your animal’s exposure to these large insects, which can grow to be 1 inch in length, by scheduling outdoor time in the morning or evening and on days when there is a steady breeze to help keep them away.

The fact that horseflies prefer to stay out of the shade means that holding horseback riding, grilling, and other outdoor activities in shady locations might be beneficial.

Visual Cues

Horseflies hunt for food in the same way that many other species do. They are drawn to things that move, such as bright surfaces and dark forms. In the event that you find yourself outside during a period when horseflies are in abundance, dressing in light-colored clothing will provide some respite. Horseflies are known to swarm near swimming pools, disturbing those who are in the water. A combination of the action of the swimmers splashing around in the pool and the bright, reflecting surface of the water is responsible for this effect on visibility.

Environmental Cues

Horseflies do not require visual contact with their prey in order to locate it. They are drawn to carbon dioxide, which animals and people emit naturally as part of the breathing process, and warmth, another result of everyday existence. There is nothing you can do to switch off these processes that attract horseflies. On the other hand, you may find some solace in the fact that horsefly season is normally extremely brief, these pests are only a nuisance for several weeks, late in the summer.
