Flea bites in humans is caused by a parasitic insect from fleas. Its is ussually appears around the feet, ankles or in legs that looks like a small red spots that often occur in two to three groups of red clusters around them.

Fleas are minuscule bugs that can live in the yard and the fur of pets. Their size does not exceed that of a pen’s tip, and their color ranges from light brown to almost black. They move about using their legs, jumping from one place to another. They have hard shells that protect their flat bodies, which makes them almost impossible to eliminate. Fleas reproduce rapidly, especially when there is a pet in the house, and the yard can be their carrier. These creatures can only be eliminated using a pesticide treatment, and worse, they can give flea bites in humans. 


If the fleas are unable to be contained, they can spread and bite in all body areas. Typically, these are the characteristics of the bites: Miniscule with a red spot on its center, appear as a group and be placed in a line which forms a scab circled by a red halo. The types of flea bites in humans usually appear in the feet, ankles, or legs. 

Humans are usually the optional carriers when fleabites are concerned because they do not make good carriers. Humans become prey for adult fleas who have yet to find the family pet, for instance.

For small children and adults who have allergies on fleas, they might experience swelling and itching. The skin surrounding the bite may become irritated and painful to touch. In some cases, hives and rashes appear, and another infection may appear if the bite is scratched. 

In most cases, fleas can be a sign that they have infested the home, but no serious symptoms can be inflicted on these bugs. 


While flea bites in humans pose no serious symptoms, they can trigger two complications: allergic reaction; and secondary infection.
