How Small Are Flea Bites?

Flea bites are tiny red bumps that usually have a small, pink “halo” in the center. They usually appear in groups of three or four, and are most often found around the legs, ankles, breasts, groin, and armpits. Those who are allergic to flea bites may notice swelling and redness, as well as small bumps or welts.

Children usually have flea bites that are more noticeable than adult flea bites. The skin of a child is more sensitive, and the immune system is not fully developed. However, flea bites on children are rarely harmful. They are often itchy, causing a strong urge to scratch the area. The bites can be soothed by using anti-itch cream, and the area should be covered with cotton to prevent infection.

Fleas are small insects that live on warm-blooded animals. Adult fleas are approximately one-sixth the size of a human, with two antennae and six legs. They do not have wings, but they have strong legs that allow them to jump long distances.

Fleas are tiny, blackish-brown, and wingless insects that live on humans, livestock, and pets. They are surprisingly small, with bodies about the size of a speck of black pepper. They move around by crawling or walking, and can jump several inches to gain access to the blood of their host.
