Fleas are flat, wingless insects that spend most of their lives on a host. Their flat body allows them to jump large distances and blend into the host’s fur. Fleas do not have wings, so they move from host to host by using their sense of smell. Adult fleas are brown or reddish in color, and have six legs. Their legs are long, and they have bristles on the back that point backwards.
Fleas are a nuisance for both humans and animals alike. They are small, and their bodies are made up of hard exoskeletons and hairs that point backwards. These hairs help them move under the fur of their host, and help them stay attached to it. Fleas use their sense of smell and antennae to find food. Their mouthparts are also long, and they feed on the blood of the host.
A flea bite will look like a red, itchy bump. If you’re allergic to fleas, you’ll experience an itchy, red rash, tickles, and small black specks on your skin. These symptoms may be the result of an infection, and you should seek treatment immediately.
Adult female fleas lay eggs on animals. Flea eggs are tiny, white, and oval. They are hard to spot, as they are so tiny. Flea larvae are tiny, white, and pale-coloured, and are similar in appearance to caterpillars. The larvae are fed off of the blood of the adult flea and feed on its droppings.
