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.
Firstly, a little zoology: fleas live about 50 days and can lay over 2000 eggs in that time[1]. Assume 10% live to adulthood; youâve got 200 little beasts that can jump several inches through the air. You need to kill off the adults and take care of the larvae to keep you and your pet free of nasty bites.
