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.
Adult fleas cannot survive or lay eggs without a blood meal, but may hibernate from two months to one year without feeding. There is often a desperate need for flea control after a family has returned from a long vacation. The house has been empty with no cat or dog around for fleas to feed on.
