How Long Do Fleas Last Without a Host?

Fleas have a unique life cycle. They undergo three stages: the egg, the hatching, and the pupa stage. If the environment is ideal, fleas can survive for up to 185 days without a host. They can also survive for weeks without a host if they are in a suitable habitat. Once they are no longer able to find a host, they will die naturally after about a week of starvation.

The pupa stage of a flea’s life cycle is long. It can last for several weeks or even years before emerging from its cocoon. Once it has found a host, the adult flea emerges and begins feeding. Fleas can survive up to 100 days without food.

Adult fleas normally live between 30 and 90 days with a host. Then they begin to pass through their four life stages, each with their own characteristics and lifespan. Fleas can survive for two weeks without a host, and can occasionally survive for a month without a host.

Adult fleas lay up to 500 eggs in their lifetime. These eggs are dispersed throughout a host’s fur. Once the larvae hatch, they lay their first egg cluster and start the life cycle all over again.
