How Do Fleas Multiply?

Fleas are small parasitic insects that can spread diseases to humans. They reproduce by laying eggs on animal skin. The eggs are carried by the female fleas and they hatch into larvae, which live in the fur of their host animals. Fleas can lay up to 500 eggs in their lifetime, which is more than the total number of eggs laid by other insects. These eggs can be spread through scratching and can result in the infection of other animals, including humans.

Fleas feed on blood from their host animals. After feeding on an animal, adult fleas jump onto another host. This means that millions of them find a host each day. Each time, they land, a new cluster of eggs is laid. Then, this cycle repeats itself.

Adult female fleas lay eggs on their host animals after a blood meal. Flea eggs hatch in two to fourteen days, depending on the environment. A warm and humid environment is the ideal breeding ground for flea eggs. A female flea can lay up to 40 eggs per day, and a single female can lay up to 500 eggs in her lifetime.

Fleas lay eggs in clusters of up to 20. The number of eggs varies, but the average number of eggs laid by a female flea is fifty. The amount of blood a female flea can draw from her host determines how many eggs she will lay each day.
