How To Get Rid Of Horseflies 

Are you wondering about how to get rid of horseflies? If so, it’s probably because you have noticed an influx of these annoying and biting pests. Horsefly season is upon us, starting in May and likely to stretch until September.

And while horseflies are not always dangerous to people, their bites are painful and their presence is obnoxious. So, how do you get rid of horseflies?

If you’re asking this question, you’ve come to the right place. Let’s find out more about horseflies and how to manage them for good.

But First, What Are Horseflies?

Horseflies are large, biting flies commonly known to bite horses and livestock.

Horseflies are large, aggressive flies that are known to bite humans and other animals. As their name suggests, they are common around farm animals like horses and cattle, but they can also be common in any environment conducive to their needs.

Horseflies can be confused with mosquitoes because they have similar habits, including biting people to feast on blood and leaving behind itchy bumps or welts. However, unlike mosquitoes, horseflies are not known to transmit diseases to human beings.

And while horseflies are commonly found around barns, ranches, and other similar locations, these pests can be common almost anywhere if the conditions are right.

In fact, horseflies are found throughout the United States, where their preferred habitats include wet meadows, marshes, ponds, and streams. Because of their preference for still water and damp areas, horseflies prefer to breed in standing water such as ponds or shallow depressions in the ground.

As we mentioned above, horseflies feed on mammals’ blood. These flies often bite livestock, sometimes causing wounds that become infected with bacteria from manure or rotting vegetation.

Though they can be mistaken for horseflies because their bites may cause similar reactions, horseflies actually look quite different from their mosquito counterparts.

Adult horseflies have large eyes that give them good vision even in low light conditions; they also have long legs with spiny feet designed for grabbing onto animals’ hides when they try to escape from being bitten by one of these pests. Horseflies also have large antennae, and their bodies are hairy or bristly.

The larvae of horseflies are known as “wigglers” because they wiggle around while swimming in water. They have a distinctive red tail, which helps them stay upright as they swim.

Horsefly larvae live in shallow water where they eat algae and other organic matter. When they are ready to become adults (called pupae), they leave the water and move onto land. The males emerge first, followed by the females about two weeks later.

Horsefly adults do not eat solid food; instead, the females need blood from an animal (or human) to produce eggs. The more blood she consumes, the more eggs she can produce! The larvae hatch from these eggs, which fall off into water where they develop into pupae before emerging as adults.

Are Horseflies Dangerous?

Just because horseflies are not known to spread disease or illness to people through their bites, their bites can be quite painful and these bites also leave behind itchy sores and irritated welts.

Furthermore, horsefly bites can become infected from secondary infections due to itching or scratching the area that was bitten, though this is rare so long as the person who is bitten takes care to wash and treat the bite as needed.

Horsefly bites can be dangerous, however, to animals. Some of the most common diseases horseflies can spread to animals include some forms of trypanosomes, equine infectious anemia virus, tularemia, and more.

What Attracts Horseflies?

Horseflies are attracted to mammals like horses, livestock, and sometimes even people.

Like mosquitoes and other biting flies, horseflies are attracted to the smell of carbon dioxide we breathe, the sweat mammals produce, and even certain colors we wear or our body heat.

As we mentioned, horseflies feed on horses but they will also bite people and other animals such as cattle or deer. Horseflies bite mammals because they need blood to produce eggs and larvae (the immature stage between egg and adult). Female horseflies lay their eggs on grasses near water sources where the larvae will live before maturing into adults.

This means that horseflies can be attracted not only to people and animals but also to certain environments.

Environments with stagnant water sources or marshy grasslands can be an ideal home for these annoying pests.

If your yard or property has stagnant water sources like play pools, ponds, lakes, bird baths, or even overwatered lawns and drainage, you could be inviting horseflies.

To work on how to get rid of horseflies, the best thing to do is be proactive in the methods you use to not only repel them but also keep them from coming back.

We have listed some of the best practices below you can follow for how to get rid of horseflies.

  • Marigolds
  • Peppermint
  • Garlic
  • Chives
  • Catnip
  • Basil
  • Bay

  • And Tansy

Common Horsefly Predators

One method you can use for how to get rid of horseflies is to invite the horsefly predators. Like many flies, horseflies have an abundance of natural predators, including dragonflies, wasps, and spiders.

You can encourage these predators to visit your property by planting flowering plants like dill, parsley, and fennel. These plants attract both adult and larval insects that prey on horseflies.

Other predators you might consider inviting to your property include:

Dragonflies and damselflies.

  • These colorful flying insects are voracious predators of both adult and larval flies. They eat the flies in mid-air, catching them with their long, grasping legs. Dragonflies can also snatch up a fly that lands on a pond’s surface with their lightning-fast reflexes.

Praying mantises.

  • These large, greenish insects have powerful front legs that they use like pincers to grasp prey tightly while delivering a lethal bite to its head or neck area with their sharp “jaws.” Praying mantises can easily catch large flies in flight or when they land on vegetation or other surfaces around your home or property.


  • Birds such as bluebirds, robins, swallows, and starlings eat many kinds of insects including horseflies. If you want to invite these birds to your property, make sure there is plenty of food for them in the form of berries and seeds. You can also create birdhouses and out bird feeders.


  • Frogs are famous for their appetite for flies, and horseflies are certainly on their list of favorite meals. If you have a pond on your property, consider planting lily pads (which are edible) so that frogs have somewhere safe to lay their eggs while they’re away from home hunting

Make Your Own Vinegar And Soap Horsefly Spray

Horseflies and many other insects and pests are deterred by the smell of vinegar and soap. You can use this to your advantage and make your own horsefly spray using these very ingredients.

Here’s how to make your own vinegar and soap horsefly spray for how to get rid of horseflies:


  • 1-2 cups of water
  • 1/3 cup of white vinegar (preferably distilled)
  • 1/3 cup of liquid castile soap, such as Dr. Bronner’s (or any other unscented, organic liquid soap). You can adjust the ratio according to how much you want to make; just keep it at 1:2 or 2:1 vinegar to soap.


Mix the above ingredients together in a spray bottle and spritz this on your body, clothing, or even your horse. (If you do spray this on your horse, be sure you are using soaps that are safe for animals and that will not irritate your horse’s skin or coat).

You can also use this method as a form of natural cleaning product around your home.

Make Your Own Horsefly Trap

While a fly trap is not going to be the most effective home remedy you can use for how to get rid of horseflies, it can help you monitor your progress and keep an eye on which other methods are working best.

To make your own horsefly trap, you will need the following:

  • A small plastic container with a lid
  • A small piece of cardboard (cut from the center of a cereal box)
  • An old piece of window screen or fly screen mesh
  • A kitchen knife or a pair of scissors


  1. Cut out a square about 4 inches across from the piece of cardboard and place it in the bottom of your container.
  1. Cut out an opening at one end of your square so that it fits over the top of your canning jar lid. The opening should be just large enough for the horseflies to enter but too small for them to escape once they are trapped inside. You may want to experiment with different sizes until you find one that works best for you.
  1. Using an old piece of window screen or other porous material, wrap it around your cardboard square (now attached to the bottom of your canning jar) so that it forms a funnel shape with open ends on either side facing up into your jar’s mouth. This will make it so the fly can get into the trap but will be unable to get out.
  1. Bait the fly trap with apple cider vinegar or molasses mixed with a little water and spread over the top of your funnels.
  1. Once you have everything set up, hang your fly trap in a shady area where you see horseflies buzzing around most often. Be sure to check on your trap often and empty out any dead flies as they accumulate inside!

Keeping horseflies under control can take time and patience.

While determining how to get rid of horseflies may seem like a daunting task, it really just takes a bit of time, a few changed habits, and some consistency to ensure these files are managed.

Horsefly prevention begins with sanitation. Horseflies are attracted to the scents left behind by animals and people. Horseflies are also attracted to standing water sources, so make sure there is no standing water where they can lay their eggs. This will also help prevent mosquitoes from breeding in your backyard.

Mulch around your trees will help keep horseflies away from the area where you spend most of your time outdoors. If you have a garden or flowerbeds, place mulch around them as well.

And remember, while horseflies are not dangerous to people, they can be dangerous to horses and livestock. If you do have a horsefly infestation that you feel you cannot manage on your own, it is best to contact a professional pest control company in your area for further assistance.

We hope this has been a helpful guide on managing horseflies! Best of luck with keeping these pests at bay and thanks for reading!
