Search flea bites Of all insect or arthropod bites, flea bites are among the most common.
Fleas lay their eggs in dusty areas, rugs, and cracks between floorboards.
The eggs hatch and produce larvae that then form cocoons. The cocoons lie dormant and can live for up to a year. The adult flea emerges in response to vibrations from footsteps. This accounts for the unpleasant surprize people sometimes get when they occupy a house that has stood empty for a number of months. Once hatched, adult dog fleas can live for up to two months without a blood meal.
