How Biting Flies Bite
Biting flies have specialized mouthparts designed to pierce the skin and suck blood. The process of biting can be quite painful, and it often leaves behind a red, itchy bump. Here’s a closer look at how biting flies bite:
-
The fly lands on its host and uses its proboscis to locate a suitable spot to bite.
-
The proboscis is a long, slender tube that can be extended and retracted. It contains a sharp needle-like tip that pierces the skin.
-
Once the skin is pierced, the fly injects saliva into the wound. This saliva contains anticoagulants, which prevent the blood from clotting, and anesthetic agents, which numb the area.
-
The fly then starts to suck blood, which can cause swelling and itching.
-
After feeding, the fly leaves its host and may deposit eggs in the vicinity.
Risks Associated with Biting Flies
Biting flies can pose several risks to humans and animals, including:
-
Disease Transmission: Many biting flies are vectors for diseases such as malaria, dengue fever, yellow fever, and leishmaniasis.
-
Discomfort and Pain: Biting flies can cause significant discomfort and pain, especially when they bite in sensitive areas.
-
Swelling and Infection: Biting flies can leave behind red, itchy bumps that may become swollen and infected if not treated properly.
-
Loss of Blood: In some cases, biting flies can cause significant blood loss, especially in animals.
Preventing Biting Flies
There are several ways to prevent biting flies from becoming a problem:
-
Use insect repellents: Applying insect repellents containing DEET, picaridin, or oil of lemon eucalyptus can help repel biting flies.
-
Wear protective clothing: Long-sleeved shirts, pants, and hats can help protect you from biting flies.
