Flea eggs refer to small, round or oval-shaped eggs that are laid by fleas. These tiny eggs can hatch into larvae and eventually grow into adult fleas if left untreated. Flea eggs are usually found in areas where pets sleep, rest or spend most of their time, such as beds, sofas, carpets, and rugs. They are white, about 1/50th of an inch long, and can be easily detected with the naked eye if they're laid on a light-colored surface. Flea eggs play a crucial role in the life cycle of fleas as they hatch into larvae that feed on organic matter such as skin cells, hair, and other debris found in carpets or upholstery.
