How To Identify And Get Rid Of Biting Flies

There are many species of biting flies in the United States, which can make it difficult to identify a particular pest that’s bothering you.

Biting flies are not only annoying, but they can also be harmful to your health. These pests typically feed on both human and animal blood and can even transmit harmful diseases. Some types of biting flies can also cause serious allergies to flare up in sensitive people.

In today’s article, we are going to talk about how to identify and get rid of biting flies around your property.

But before we begin, let’s start by talking about some of the most common biting flies you might be coming across.

How Many Types Of Biting Flies Are There?

There are thousands of fly species and countless flies that bite.

As we mentioned above, there are a number of species of biting flies in the United States, so identifying the ones “bugging” you could be tricky. Luckily, we’re here to help. Some of the most common biting flies that are prone to biting humans include:

  • Deer Flies
  • Mosquitoes
  • Biting Midges
  • Gnats
  • Black Flies
  • Stable Flies
  • Sand Flies
  • Yellow Flies
  • And Horse Flies

Let’s take a moment to learn a bit about each of these frustrating pests.

Deer Flies

Deer flies are a small species of fly that are often confused for bees thanks to their unique black and yellowish coloring and striped bodies. They feed on the blood of humans and cattle and bite using mouthparts that are formed like scissors. Though these pests are smaller than horse flies, their bites can be just as painful.

Deer flies are attracted to bodies of water, the carbon dioxide released from our breath, and movement.


Some people don’t realize that mosquitoes are in the fly family, but alas it is true. These pests are some of the most formidable when it comes to biting flies due to the number of serious diseases they can transmit to people and animals. Some of these illnesses include the Zika virus and West Nile virus.

Mosquito bites don’t always hurt initially, but most people can have an itchy and sometimes even painful reaction to the bite later on. Like Deer flies, mosquitoes are attracted to water sources and carbon dioxide.

Biting Midges

Also known as no-see-ums due to their small size, biting midges are one of the most prevalent biting fly pests in the United States. While they often attack people, they are most dangerous to animals and particularly cattle and sheep.

Biting midges are known to transmit a disease to animals known as Blue Tongue Fever. This illness is prominent primarily among sheep and does not affect humans.

Biting Gnats

There are many species of gnats in the United States and not all of them bite. However, those that do belong to our group of biting flies you’ll want to stay away from. They are very small and often travel in large groups known as clouds.

Though this species of biting fly can cause painful and annoying bites to people and animals, the good news is that they are not generally known to transmit diseases.

Gnats are attracted to fruits and sweet smells. They are often found congregating around decaying organic matter like garbage and meat.

Black Flies

Black flies, also known as blackflies or buffalo gnats, are a common biting fly in the United States that tend to pester both humans and animals. Though these insects are smaller than the average house fly, black flies are a species of biting fly that can cause you to bleed and itch.

With that being said, their bites do not cause illness or disease. They are most common near running water sources like streams and rivers, where they often breed and lay their eggs.

Stable Flies

As their name suggests, stable flies are common barn, stable, and ranch flies. These pests bite both animals and people and are known to spread diseases including anthrax and EIA or Equine Infectious Anemia.

They are highly attracted to the carbon dioxide released in our breath as well as blood. The most commonly bite people on their lower extremities like their legs, ankles, and the backs of their knees. Their bites are quite painful and highly irritating.


Sandflies are small, brown pests that bite both people and animals and feed on blood. Though they are quite small, these pests can transmit serious diseases including a parasitic virus known as Leishmaniasis.

These biting flies are attracted to areas where humans congregate and live, though they are also found in caves and near rock formations, which is one of the reasons they are known as sandflies.

Yellow Flies

Yellow flies are related to deer flies and horse flies. Only the female yellow flies bite, relying on iron in the blood to help them breed and lay eggs. Male yellow flies are actually considered beneficial pollinators as they feed on nectar and pollen from surrounding plants.

Female yellow fly bites can be painful and lead to itching, swelling, and irritation. However, unlike many of the biting flies on our list, these pests are not known to carry or transmit diseases to humans.


Horseflies are very large and can deliver a painful bite. This may be one of the reasons they are the most infamous of the biting flies on this list. As their name implies, horse flies are an incredible annoyance to horses.

They can carry equine infectious anemia or swamp fever, which is life-threatening to horses. When it comes to humans, however, horse flies do nothing worse than delivering a painful bite.

Are Biting Flies Dangerous?

Some biting flies are simply annoying while others can carry and transmit serious diseases.

Although the majority of biting flies can cause pain and discomfort when they bite, not all of them are considered medically important to humans.

However, there are a few biting flies that are considered dangerous to both people and animals, as we mentioned above.

The most dangerous biting flies from our list above include flies like:

  • Mosquitoes
  • Sand Flies
  • Deer Flies
  • And Stable Flies

With that being said, other biting flies on our list can lead to a severe allergic reaction known as anaphylaxis in sensitive people. Anaphylaxis is a life-threatening reaction that leads to breathing difficulties, lethargy, nausea, vomiting, collapse, and loss of consciousness.

This is a medical emergency that can come on suddenly after a bite and requires expert attention.

The good news is that most people bitten by flies will not develop an illness or an allergic reaction. Instead, the most common reaction from a fly bite in the United States tends to be itching, redness, and irritation.

If you are bitten by a fly, it is best to clean the area thoroughly and apply over-the-counter medications that contain antihistamines to the affected skin. Refrain from scratching at the bite, as this can lead to irritation and secondary infections.

Mosquitoes especially are considered dangerous biting flies, and many products you buy at the store or order online are designed to prevent them from biting.

When it comes to bug sprays that repel biting flies, most experts recommend a formula containing DEET. DEET is a chemical agent proven to effectively keep pests like mosquitoes, biting midges, and other biting flies at bay.

Some essential oils can help repel and reduce biting fly problems

If you’re in a pinch and looking for a quick fix for your biting fly problem, you’re in luck. Not only can you run to the store or jump online and find a number of products to get rid of biting flies, but you can also make your own remedies for biting flies by using household ingredients.

In fact, many of us already have products in our homes that could deter biting flies on our property. You may even have products in your medicine cabinet or pantry that you can use to protect yourself or your pets from biting flies.

Try Using Essential Oils

Flies have a fabulous sense of smell, and they are often attracted to the scent of carbon dioxide we breathe. This odor tells them a blood meal is nearby, so one of the best ways to deter biting flies is to muddy this smell.

To do this, we recommend using essential oils like peppermint oil, citronella oil, rosemary oil, lavender oil, eucalyptus oil, or tea tree oil.

You can dab a bit of this oil directly on your pulse points to keep pests from biting, or you can make your own essential oil bug spray.

To make your own natural bug spray to deter biting flies, simply combine two cups of water and 15 to 20 drops of the essential oil of your choice. Mix this solution in a spray bottle and spray it on your body as well as around the areas you’ll be congregating outside.

Make Your Own Fly Trap

There are two ways you can go about making your own fly trap to capture and dispose of biting flies.

The first way includes using a mason jar, a slice of fruit and a piece of paper rolled into a funnel. Place the fruit into the jar and put the funnel-rolled paper with the small side down into the jar. This will allow the flies to get into the jar but will keep them from getting out.

The fruit inside the jar will act as an attractant to flies, so put this jar away from the area you will be congregating. The lure should help to attract flies and keep them from biting you while simultaneously capturing them.

Another biting fly trap that works well requires the use of honey and construction paper. Coat a piece of construction paper with sticky honey and leave it outside in areas away from where you will be. Flies will be attracted to the sweet smell of the honey and become stuck.

Home Remedies For Soothing Fly Bites

Along with using do-it-yourself methods for biting fly control, you can also use home remedies to soothe fly bites.

Some of the best household ingredients that can help soothe fly bites include:

  • Oatmeal
  • To use oatmeal to soothe a bug bite from a biting fly, combine the dry oats with a bit of water and mix it into a thick paste. Then apply the paste directly to the affected area. The oatmeal contains soothing properties that can alleviate itching and help to reduce inflammation.
  • Aloe Vera
  • Aloe vera is a natural plant-based substance that is incredibly healing and soothing. Most of us know it’s great for sunburns, but it can also help reduce itching caused by bug bites. This includes bites from biting flies. Simply dab a bit of aloe vera on the affected area and repeat the process as needed.
  • Witch Hazel
  • Witch hazel is a plant that is often used to make medicines and toners. It has healing properties that can reduce inflammation and irritation, making it a natural remedy for biting fly bites. To use this method, apply witch hazel to a cotton ball and hold the cotton ball on the affected area.
  • Ice
  • If all else fails and you’re struggling with an annoying fly bite, try applying ice to the location. Ice will help reduce inflammation and can even temporarily numb the area to stop the itching. Do not hold ice on your skin for longer than a minute, however.
  • Over The Counter Antihistamines
  • Many antihistamines you may already have in your medicine cabinet can work for bug bites and fly bites. These include antihistamines like Benadryl and Lotradine.

Some of the best tips and tricks for preventing biting flies, according to experts, are listed below:

Remove Their Breeding Ground

Many biting flies are attracted to water sources, but the types of water are different for different species. The mosquito, for example, is attracted to stagnant water sources while the black fly is more prevalent around running water sources like rivers and streams.

  • Bats
  • Birds
  • Frogs
  • Toads
  • And Spiders

Try Companion Planting

As we discussed briefly above, flies have a great sense of smell. Not only can essential oils help keep biting flies at bay, but so can strategically companion planting specific plants around your garden.

Some of the best plants that are known to repel pests include plants like:

  • Thyme
  • Lavender
  • Peppermint
  • Basil
  • Garlic
  • Mint
  • Petunias
  • Lemongrass
  • Chrysanthemums
  • Sage
  • And Catnip

Keep Your Yard Clean And Tidy

Last but not least, be sure to keep your yard clean and tidy. This could include routine landscaping, cleaning up pet waste, refraining from leaving food outdoors, removing debris, and raking up leaf litter.

And remember, not all biting flies are dangerous, but most biting flies do hurt and cause discomfort. Prevention is key when it comes to keeping biting flies at bay.

With all that noted, we hope this has been a helpful guide on how to keep these pests from “bugging you” once and for all!
