Flies are a nuisance. You have probably seen flies both indoors and outdoors, buzzing around and landing on kitchen counters and right on your food. There’s a good chance you also already know flies are unsanitary because they tend to land on garbage, feces and other dirty objects. This causes the flies to pick up bacteria, which they can transfer to food and cooking surfaces which can create health risks for you. But did you know some fly species bite?

Several species of fly need blood in order to reproduce and will gladly bite humans to get this blood. These flies need the proteins to create eggs. Western Exterminator fly control specialists are experts in most fly species, including biting flies. We can help you get rid of flies in your home and around your property. Contact your local Western Exterminator office today.


Why do flies bite?

Flies need not consume blood in order to live. So, why do flies bite in the first place? Most species of flies prefer other food sources, such as nectar from plants. However, for reproduction, flies need the proteins found in animal blood in order to mate and produce eggs.

Flies have special mouthparts like mosquitoesfleasticks and bed bugs allowing them to pierce the skin and access blood vessels. They also inject anticoagulants contained within their saliva, which allows the blood to flow freely into their bodies.

Are fly bites dangerous?

Fly bites do carry some potential health risks. Some viruses and bacteria can be carried by the insects in their systems which can be transmitted to humans and animals via their saliva. Fortunately, the biggest risks tend to affect other animals. Horse flies, for example, can carry anthrax, they can transmit to sheep or cattle. However, some species of biting flies can transmit disease such as:

  • Sand fly fever
  • bartonellosis
  • leishmaniasis
  • tularemia

The bites of black flies, stable flies and horse flies can be painful to humans, and those sensitive to insect bites and stings can experience allergic reactions.

Which flies bite and what do the fly bites look like?

Fly bites may look different depending on the species involved. Since each species of fly is a little different, it can depend on where you are and which fly has chosen you for its blood meal.

  • Horse flies - These are large, dark, flies and their bites are painful. Their mouths have nasty cutting and slicing parts, described as tiny razor blades which cut through the skin down to the blood vessels. These bites leave behind red bumps or rashes.
  • Sand flies - The bites of these much smaller flies are a little more typical of an insect bite. They usually appear as red bumps, much like mosquito bites. However, you are likely to find a large cluster on your ankles, legs and feet.
  • Deer flies - These flying pests are in the same family as horse flies and have the same cutting, slicing, razor-like mouthparts. There’s a good chance you’ll feel the bite as it happens. You’ll see blood and end up with red welts and rashes.
  • Black flies - The bite from these flies are like sand flies: small, red, bumps. These flies show up during the spring and summer and love to be near water like lakes, creeks and rivers.
  • Gnats and biting midges - These are tiny insects which will bite when you venture into hot, humid areas. These bites often hurt and you’ll feel them, but you probably can not see the teeny culprit. This is why these flies are sometimes referred to as “no-see-ums.” Their bites also strongly resemble mosquito bites and appear as red bumps.
