Where Can Fleas Live on Humans?

Fleas are tiny insects that live on humans and animals. They are usually 1.5 to 4 millimeters long and have flat, dark brown bodies with mouth parts that pierce and suck. Although fleas are generally not dangerous to humans, their bites can be painful. Fleas feed on blood and can carry disease and parasites.

The bites of a flea usually appear as small red bumps, often appearing in clusters. They are often mistaken for mosquito bites. Fleas tend to bite humans in the lower half of the body, though they can bite any part of the body. The most common areas to get a flea bite are the arms, legs, and ankles.

Fleas can live up to 100 days without a host, although they prefer pets. If they had to go without a blood meal, they wouldn’t be able to lay eggs, and their population would eventually dwindle. When they find a blood meal, they will lay eggs within a few days.

Fleas are found on pets, clothing, and outdoor materials, but they can also live on humans. Fleas can attach themselves to the skin and travel on your clothes, shoes, and luggage.
