When Do Fleas Go Dormant?

Fleas are parasitic insects that lay eggs and lay pupae in our homes. They feed on organic matter and prefer darkness over light. After hatching, they lie dormant for weeks or even a year before emerging as adult fleas to feed, mate, and lay eggs.

Fleas require warm, moist weather to survive, and they are most common in Florida and other warm, humid areas. Fleas will typically be inactive during the coldest months of winter, but they will emerge in the early fall and resume feeding once temperatures drop.

It is important to keep your home free from fleas and to treat them regularly. You can begin treatment for fleas when your pet is at least 8 weeks old. Using a preventative is the best way to protect your pet from this serious disease. Fleas can live in your home for two years and can be present even in a new home. Flea eggs hatch when the house warms up and they begin looking for a host.

To treat the whole house, you can use an insecticide that kills flea eggs and larvae. It is important to keep your home free of fleas for at least two weeks after the treatment. This way, you can minimize the need to spray your home and limit the frequency of flea infestations.
