What Size Are Fleas?

Fleas measure 1 to 3 millimeters long, with the female fleas being larger than two millimeters while the males are smaller and can be as small as one millimeter. The flea’s thick back legs and antennae help it navigate and stay attached to its host. They have small eyes and extend mouthparts, and feed on blood.

Fleas don’t have wings, but they are excellent jumpers. They can jump up to eighty percent of their body length, which allows them to jump long distances. Despite the fact that they can jump a long distance, adult fleas can be hard to see because of their color and ability to hide.

Fleas feed on the blood of their host, and they use the body of their host as a breeding ground. A single flea can live up to 100 days without feeding. A female flea can eat up to 15 times her body weight in blood per day. By the time she’s finished feeding, she’ll have produced as many as 50 babies.

A flea’s lifespan depends on the food and shelter it has. They can live up to two weeks without a host and can survive for eight days on short-haired animals but longer on long-haired animals. Female fleas can lay eggs within two days of their first blood meal. A flea’s size is an important factor when it comes to treating a flea infestation. If you have a pet with a flea infestation, it’s important to treat it as soon as possible.
