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 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.

Women (again, as is the case with mosquitoes) bite both animals and humans in order to collect protein in the form of a blood meal, which they use to fertilize eggs. 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.

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. If you want excellent personal protection against flies (and mosquitoes), use Maggie’s Farm Natural Insect Repellent, which is made from plant oils.

Always read and carefully follow the recommendations on the label of any pest control product, including those for storage and disposal.

What Attracts Horseflies?

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.

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.

  • 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.

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).

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.

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

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.

Recommended Read:The Life of a Horse Fly

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. Horse fly repellent sprays can be effective against these insects, but they can be difficult to find. It is advised that you use a horse fly repellent spray that is specifically designed to repel horses.

It may be a perfect answer for the summer months when they are at their most active, which is when they are most prevalent.

Thank you in advance for your assistance — I much appreciate it! My next-door neighbor’s son just showed us his arm, which was covered with horsefly bites. He claims that if he goes within a mile of a horsefly, it chases him away. I was intrigued by his statement, and I began to wonder why horseflies bite and whether they actually do hunt people.

Protein is required for the development of their fertilized eggs.

And, sure, horseflies will hunt you down in order to acquire their food from your blood.

If you’ve ever been chased by horseflies, you’re well aware of how unpleasant the experience can be. But can horseflies bite and chase certain individuals more than others? This is one of many questions I get asked about horse fly behavior, and this is one of the answers I provide.

Horsefly bites

Horsefly bites are painful and can result in swelling, itching, and a burning feeling. It’s also conceivable that a horsefly bite can leave a bruise on your skin. The good news is that horsefly bites do not usually result in long-term health problems in people. To make matters worse, horseflies are extremely deadly to horses because when they bite, they emit anticoagulants from their saliva, which helps to keep the blood flowing. Equine infectious anemia, which can be deadly in certain horses, can be carried and transmitted by saliva.

Why are horseflies so aggressive?

In addition to their aggressive attitude, horseflies are also notorious for their blood-feeding habits. Their hunger increases as a result of their exposure to humans and other animals, and their aggression increases as a result of their search for food. Female horseflies are active, flying around in search of blood meals that will offer the protein necessary for the growth of their fertilized eggs; male horseflies are passive, hanging out on flowers and other plants. As soon as a horsefly has selected a target, it uses its strong jaws to pull free skin and drain blood from the flesh of animals and people.

Furthermore, when horseflies bite people, they do not begrudge us their strength; they utilize the same biting force on us as they would on a thick-skinned animal.

In order to survive, male horseflies must feed on pollen from plants.

How do you keep horse flies from biting you?

We recently had some friends over, and we knew they would be interested in seeing some of the horses we kept in our stable, so we prepared accordingly. Knowing this, I took precautionary measures to decrease the likelihood of horseflies causing us discomfort. Use horsefly repellent, remove stagnant water, maintain your barn free of manure and trash, set up horsefly traps, and light citronella candles in the surrounding area are all important steps in preventing horseflies from biting people and animals.

Horseflies are a nuisance that both you and your horses must deal with.

Can horse flies bite through clothing?

Some individuals believe that wearing long sleeves, shirts, and slacks that cover the majority of their skin will keep horseflies away from their skin.

Horseflies, on the other hand, can bite through clothes, fur, and animal skin, whereas other insects are deterred by clothing.

Why do horseflies bite me and not others?

When it comes to horseflies, they are most active during their mating season, which occurs in the summer. And they always seem to bite the son of my next-door neighbor. Consequently, I was curious as to whether there is a reason why they bite certain people but not others. Horseflies are attracted to certain individuals more than others. Horseflies are attracted to humans by motion, dampness, dark hues, and specific fragrances. Horseflies are attracted to children and adults who are dressed in dark clothing, notably dark blues, moving fast, and sweating.

Horseflies will not regard two people in the same way if one is sitting peacefully and dressed in bright attire, and the other is rushing around sweating and clothed in a dark blue costume.

What do horse flies hate?

To battle horseflies efficiently, you must first understand your adversary. To put it another way, what do horseflies despise and will keep them away from your home? Do they have any particular odors or colors that they avoid? Horseflies are particularly attracted to some herbs, including eucalyptus, rosemary, basil, lemongrass, and clove. It appears that they also avoid Avon Skin-So-Soft, as well as apple cider vinegar, white vinegar, and citronella. Some of these smells are used in commercial horsefly sprays, and they are quite efficient in keeping horseflies away from the horse.

Will horseflies chase you?

First and foremost, it is critical to emphasize the fact that horseflies are capable of chasing you down the street. When a female horsefly lights on you and is pushed off before it can complete its protein requirements, she will frequently return and attempt again. If you begin to move away from the house, the tenacious pest will pursue you. Horseflies are attracted to people for a variety of reasons other than the need to get blood. For starters, they are drawn to moving objects, particularly dark moving objects that are warm in temperature.

  • Horseflies are attracted to people who move around a lot because they see it as a constant.
  • I occasionally go for a run at a park that is surrounded by trees and has a pond in the middle.
  • After a while, I came across a group of walkers, and the horsefly opted to annoy them rather than bothering me.
  • During the hottest part of the day, their activity is heightened.
  • Moreover, based on my own running experience, I am aware that they want warm, sweaty bodies.
  • Generally speaking, pheromones are substances created and released into the air by animals or insects that have the ability to influence the behavior of other members of their species.
  • When a person is really involved in their workout, they may gallop by a few horseflies, and when the horseflies detect the aroma of pheromones and perspiration, they will take off after the individual.
  • You may, however, take precautions to reduce the likelihood of horseflies pursuing you.

Things like restricting your physical activity to colder weather, using fly spray, and even dressing in brighter colors can all help to keep horseflies from chasing you about. If you find yourself being pursued by horseflies on a frequent basis, these suggestions are definitely worth considering.

Are horseflies good for anything?

Horseflies are known to carry lethal infections, agitate animals and people, and inflict a severe bite on their victims. Even the most little things in our lives, however, usually have some usefulness to them. So I was curious as to what advantages horseflies bring. Horseflies are harmful to everyone and everything. You may use your creativity to make the case that they are a component of the environmental food chain. However, because it is used as a food source, its influence is minimal. Yes, horseflies are consumed by birds, but not in sufficient quantities to have a significant influence on their diet.

Where do horseflies live?

During the summer, it seems like horseflies are everywhere, and a handful of them are particularly bothersome in the swimming pool, where they regularly annoy our customers. Because our horse stable is more than 100 yards distant from the pool, I was intrigued by their appearance and wondered whether they lived close. Between May and September, horseflies are at their most active during the summer months, congregating in the vicinity of horse barns and pastures. They do well in warm, damp environments.

Our swimming pool is located behind our house, although it is surrounded on three sides by grassland.

Horse Fly Control: Get Rid of Horse Flies in the House

  • A horse fly’s body can be anywhere between 12 and 14 inches long depending on its size. Color: They are either black or gray in appearance. Eyes: People with huge, dazzling green eyes are common. Antennes: Horse flies all have antennae that are shorter than the length of their bodies


The female horse fly, which feeds on blood, has blade-like mouthparts that cut tissues and blood arteries, causing blood to flow to the wounds they produce. Females then soaking up blood with their sponge-like mouthparts is what they are known for. Males solely eat on pollen and nectar, and their mouthparts are identical to females’, but considerably weaker.

Horse Fly vs. Deer Fly

Horse flies and deer flies are closely related, and both are members of the Tabanidae family. The two most distinguishing characteristics of them are their total size and the shape of their wings. Horse flies are often significantly bigger than other species, with a stouter body and a very massive head with extremely huge eyes. When it comes to their wings, they are often transparent or hazy, whereas deer flies have black bands or patches across their wings.


While male horse flies feed on pollen and plant nectars, female horse flies are aggressive blood feeders, whilst female horse flies do not.

Finding Prey

When it comes to finding hosts, female horse flies employ a combination of chemical and visual signals in the same way that other blood sucking insects do, such as mosquitoes. A long-range indication provided by warm-blooded animals attracts horse flies from a distance, whereas visual cues such as motion, size, form, and dark color attract horse flies from a shorter distance, according to the National Horsefly Association.


They hardly seldom bite close to the head. In addition to animals of practically all sizes, horse flies also have a wide range of hosts that include humans and their pets, as well as cattle. If a female horse fly is interrupted while attempting to feed, she will fly away but immediately return to bite another host, or she will proceed to another host to take a whole blood meal from that host.

Horse Fly Bites vs. Deer Fly Bites

Large, non-moving creatures are frequently bitten on the legs or torso by female horse flies. Deer flies, on the other hand, attack moving hosts and tend to target high-up on the body, such as the head or neck, to feed.


When someone is bitten, they may experience the following symptoms and bite reactions:

  • When someone is bitten, they may experience the following symptoms and bite responses.

ReproductionLife Cycle

Horse fly growth areas include freshwater and saltwater marshes and streams, wet forest soils, and even rotting wood that has soaked up moisture from the environment. In most cases, females lay their egg masses on damp soil or vegetation that overhangs bodies of water. Larvae are active in organic stuff that is damp or wet, and they have a similar appearance to house fly maggots. Depending on the species, horse flies have anywhere from 6 to 13 larval stages. The pupal stage begins in the spring after the last larval stage has completed its overwintering period.

Fertile females will deposit their eggs on the undersides of leaves, and the larvae will hatch out and drop off the leaf in around 2-3 days after the eggs have been laid.

Horse Fly Larvae vs. Deer Fly Larvae

During field study, researchers discovered that horse fly larvae prey on midges, crane flies, and even other horse fly larvae. As a result of their cannibalistic tendencies, horse fly larvae are typically seen living in isolation. Deer fly larvae, on the other hand, tend to congregate in large numbers. Pupae do not consume food. When it comes to producing viable fly eggs, female horse flies require a blood meal to be successful. A female can lay anywhere between 100 and 800 eggs every year.


Horse flies are present in nearly every region of the United States, and there are more than 160 different species to be found.

Prevention Tips

However, even the most potent insect repellents are only somewhat successful in keeping insects away.

A better alternative for prevention is to cover and protect exposed areas of the body in order to lessen the probability of being bitten by horse flies.

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 nothing you can do to influence the weather, you may reduce your and your animal’s exposure to these large insects, which can grow to be 1 inch in length, by scheduling outside time in the morning or evening and on days when there is a continuous wind 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. Warmth (another result of everyday existence) and carbon dioxide (which animals and people make naturally during the breathing process) are two things that attract them. There is nothing you can do to prevent these systems from attracting horseflies from functioning.

On the other hand, the fact that the horsefly season is normally quite brief, with these pests only being a nuisance for a few weeks late in the summer, might provide some comfort. References Photographic Credits

What are Horse Flies? Dealing with Horse Flies at the Beach

Even while the feeling of warm sand under your toes and the lyrical sound of the ocean waves might temporarily transport you to a tropical paradise, a bite from a horse fly can soon transport you back to reality.

Horse flies, in contrast to house flies and fruit flies, are notorious for their painful and relentless biting.

What are Horse Flies?

Horse flies are extremely fast and strong fliers, with the ability to go for more than 30 kilometers at a time. Horse flies are most active in hot, humid circumstances and are drawn to bodies of water, making the beach an ideal site for them to seek refuge. In contrast to male horse flies, female horse flies must consume blood in order to successfully procreate (much like those other troublesome summertime insects – mosquitoes). Male horse flies graze on nectar. Visual hunters, horse flies frequently congregate on paths and roadsides in search of possible hosts, attacking any dark moving objects that happen to pass by.

Horse flies, often known as “greenheads,” are well-known for being persistent pests in the home.

Horse fly bites can be quite painful as a result of this.

Occasionally, they will even attempt to catch up with their intended target for a little amount of time.

How to Deal with Horse Flies at the Beach

In the same way that we like the sea and the sun, horse flies enjoy the same things, which is why beach towns are one of their favored vacation spots. The good news is that there are several methods to protect yourself and your loved ones against these pests and their sometimes life-threatening bites. For this reason, if possible, avoid beaches that are surrounded by marshland or dune grass. Horse flies are particularly prevalent in marshes and forested areas near the shore, therefore avoid them at all costs.

Although it is not ideal when the sun is blazing, if you are sitting in a beach chair or laying out on a blanket reading a book, try covering yourself in a towel or wearing long clothing to keep yourself warm.
