Adult Flea Adult fleas look brown or very dark brown in color, are about 1/8 inch long, wingless, and have three pairs of legs. The hind legs are modified for jumping and the other pairs help the flea move easily through the hair of a host. What do fleas look like in other life cycle stages? The larval stage of the flea looks like a small white worm with a dark head and can be seen moving. Flea eggs are small and white.Female fleas lay eggs loosely in the host's hair (usually a cat or dog..or squirrels and wild animals). The eggs drop off and hatch into tiny, hairy, worm-like larvae.The larvae are usually found where the animal plays, sleeps, in carpets, and on furniture. Larvae pupate and new adults emerge.The new adults immediately seek a host because they must get a blood meal to survive and produce more eggs.
