Which Flies Bite People?

Mosquitoes are actually a type of fly. Their name is Spanish for “small fly”. Mosquitoes are known to bite people to end up giving them the most dangerous and easily recognizable fly bites. Mosquitoes easily account for a maximum number of human deaths almost every year, beating all the other animals. The reason why mosquitoes drink blood is not to just survive but to reproduce or lay eggs in a better way. Mosquito bites are easy to recognize, they look like white/pinkish bumps on the skin. These bites are often extremely itchy and they cause irritation to the skin. Later on, it may turn into a tiny red bump and sometimes the bump may also have a black spot towards the center.

Deer Fly Bite

These are brown or black in color with wings that are transparent. They have small round heads with golden eyes on them. The deer flies are active during the time of spring and their larvae look similar to those of maggots.

They can spread rabbit fever which may even prove to be fatal. This may lead to ulcers on skin, headache, and fever.

Black Fly Bites

These flies are very small and have short antennae. Their wings are big and in the shape of fans. In areas of South America and Africa, these flies transfer “river blindness”. The symptoms may lead to headaches, nausea or fever.

The Process of Flies Transmitting Illness

Flies either transmit illness through their vomit or feces or by simply biting the victim. Flies often sit on garbage and trash and acquire germs from there. They then head to your food and transfer them there. Also sometimes flies vomit and secrete body fluids in order to leave pathogens there. People eating this contaminated food will end up with diseases.

When individuals modify their habitats, they reduce their chances of getting any disease transmitted by flies. The first step in control and prevention is to eliminate the sites for breeding. You can start by clearing all animal droppings, try washing your carpets more often and dispose of any fruit or vegetable that may be rotting.

Also, you can use electrical fans or fly traps to keep the flies at bay. Placing screens on doors will also help to bar them from entering.

If prevention doesn’t succeed, it is important for you to contact a pest control firm that will send professionals over to take care of the flies.
