How Fast Do Fleas Lay Eggs?

A typical female flea begins laying eggs 36 to 48 hours after her first meal. These eggs are laid in the blood of the animal she is infesting. A flea may lay up to 50 eggs a day. It takes between 36 and 10 days for the eggs to hatch. However, if the environment is conducive, the eggs will hatch much faster.

If the flea does not receive a signal from a pet, the eggs will remain dormant for up to two months. However, once they are exposed to heat and humidity, the eggs will hatch and the flea will become active. During this time, the flea will feed on predigested blood and organic debris.

Adult female fleas can lay between 10 and 50 eggs a day, depending on the temperature and humidity. The ideal environment for fleas is between 75-95 degrees and 60-85% humidity. An adult female flea can lay up to 2,000 eggs in her lifetime. During this time, it can live for up to 60 days and feed on one host.

Fleas do not have wings, so they use their powerful hind legs to jump onto their host. Their body length is one-sixteenth of an inch, but their hind legs are long enough to reach eight inches.
