Flea Bites In Humans: Pictures, Treatments & Flea Bites vs. Bed Bug Bites

Flea bites occur from small insects called fleas that attach themselves to human skin and bite to feed on human blood. Flea bites are very common and most people will have had a flea bite at some point in their life. The bite causes a mild allergic reaction on the skin that usually goes away within a few hours or days. Prescription treatment is usually not required for flea bites unless a secondary skin infection occurs.

Flea bites look like small, red bumps on the skin and usually form in a cluster on the lower legs. It’s important not to scratch a flea bite too hard, even if it may be itchy. Scratching can destroy the top layers of the skin, exposing it to bacteria that can lead to infection. Over-the-counter antipruritic (anti-itch) or corticosteroid creams can help relieve itchy skin from flea bites.

Fleas like warm weather and usually live in shrubs or trees. Using insect repellant and covering exposed skin can help prevent flea bites. Fleas also feed on animals and can live on pets with lots of fur, such as dogs and cats. Using a flea comb or treating your pet with a topical or oral flea medication can help keep fleas from getting to you from your pet.

You probably won’t need to see a doctor to get a flea bite, but if you notice leakage from the flea bite or develop a fever, call your doctor to see if you have a skin infection. Short nails can help protect your skin from scratches.
