How Fast Flea Eggs Hatch

Knowing how fast flea eggs hatch is crucial to tackling your flea infestation. The number of eggs can range from a few to hundreds, and they hatch in a matter of weeks. If you treat your pets regularly with a flea treatment, you can reduce the number of fleas in your house. However, it is not possible to get rid of all the fleas in your home. In some cases, fleas will still return after the treatment is stopped. It is essential to keep pets and their surroundings clean and dry in order to prevent fleas from developing.

Flea eggs hatch within two days to a few weeks, depending on the temperature and humidity. A dry, cold environment will take longer for the eggs to hatch, while a warm, moist environment will encourage them to hatch more quickly. Once the eggs hatch, the flea larvae emerge. Larvae are blind and do not like light, and develop over several weeks by feeding on predigested blood and other organic debris.

Female fleas can lay up to 50 eggs per day, depending on the temperature and humidity. These eggs are often not viable, because they are either consumed by their host or cannibalized by other fleas. On average, a female flea can lay over 2,000 eggs in her lifetime.
