Fly bites: Are they dangerous?

Some fly bites are considered as a health issue since some are carriers of diseases. Many have sustained fly bites, but most are simply irritating. Nevertheless, some flies can trigger undesirable symptoms.

Different types of fly bites

Sand fly

Sand fly bites are quite painful and trigger the formation of reddened lumps and blisters. These can are at high risk for infection or cause inflamed skin.

These flies can spread diseases to both animals and humans including leishmaniasis. Acquiring this disease is likely to occur when travelling to a country with reported cases.

Tsetse fly

These flies are known to feed on blood. The tsetse fly bites are also painful and cause red bumps or small, reddened ulcers at the bite site. It can even transmit the sleeping sickness to both animals and humans.

Black fly

Black flies usually bite near the face or the head. The black fly bites leave behind a miniature puncture wound and can cause minor swelling to an inflamed bump as big as a golf ball.

Deer fly

Deer flies are highly active during the spring and prefer swamps, lakes and other bodies of water. The deer fly bites can be painful and cause reddened welts or bumps. A bite can transmit an uncommon condition called rabbit fever.

Biting midges

The biting midges are only 1-3 millimeters in size. A bite can cause small-sized, reddened welts. Generally, the bites can be intensely itchy, and one feels that there is something causing bites.

In other regions of the globe, they can spread filarial worms to humans which thrive within the skin. This results to dermatitis and lesions in the skin.

Stable fly

The stable flies are strikingly the same as the standard house fly but smaller in size. These flies are present all over the globe and prevalent around livestock.

The stable fly bites can be felt as piercing needles and likely to manifest on the ankles, feet, legs and rear part of the knees. Reddened rashes and miniature, elevated red lumps are likely to form at the site of the bite.
