In a humid environment, over 60% of newly hatched fleas can live without a host for 2 months. In a cool, dry environment, only 10% will live without an immediate host. Humidity is the key to flea survival.
Completion of the life cycle from egg to adult varies from two weeks to eight months. Normally the female flea lays about 15 to 20 eggs per day up to 600 in a lifetime. Usual hosts for fleas are dogs, cats, rats, rabbits, mice, squirrels, chipmunks, raccoons, opossums, foxes, chickens, and humans.
