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.
Fleas are very hardy insects. They can live outside until we have a hard freeze for weeks. Inside your home they can live in carpet, furniture, hardwood floors and even in tile and concrete. Fleas can hibernate for up to 2 years. This may be why if you move into a new home, your house can become infested with fleas.
