Flea bites on humans can occur in any part of the body, but most commonly fleas bite the lower part of the leg, mainly feet and ankles. These areas are close to the ground hence are easy target for the fleas. However flea bites on humans can appear in the upper part of the body, if, for example, your pet sleeps in your bed or climbs on the sofa.

What Are Fleas?

Fleas are tiny wingless insects which are adapted for piercing the skin and suck blood of warm-blooded animals. Adults fleas are up to about 3 mm (0.12 in) long and they range in color from light brown to almost black. These parasites are well adapted for jumping and can jump upwards more than 30 cm (13 in).

The life cycle of fleas is typical for an insect: the female lays eggs on the host animal. Several days later the eggs hatch and begin developing as a larvae. At a later stage they change into pupae until they are ready to emerge as adult fleas. The main goal of an adult flea is to suck blood and reproduce.

Adult fleas usually live for 2-3 months, and under ideal conditions of food supply and temperature it can live much longer, but without a host to feed on, its life span can be only several days.

Sometimes bed bug bites are confused with flea bites, as both can cause severe itching, redness, inflammation and swelling. But while flea bites on humans occur at any time you are around the house, bed bugs are mostly active when it’s dark, so you will be bitten while you are asleep.

Flea bites on humans appear more like clusters of small red spots and they don’t always swell. Bed bug bites tend to appear more inflamed and become red, swollen, raised and look more like mosquito bites with the possibility of forming blisters. Bed bug bites also tend to appear in a straight pattern.

Flea bites on humans commonly appear on the legs and ankles whereas bed bug bites are located all around the body, mostly on the face and arms.
