Flea Larva

Natural Habitat

Found in dark, humid environments such as carpets, upholstery, pet bedding, and floor cracks.

Diet & Feeding

Larvae feed on organic debris, particularly 'flea dirt' (dried blood excreted by adult fleas).

Behavior Patterns

They are photophobic (avoid light) and move toward the base of carpet fibers; they undergo three larval stages before spinning a cocoon to pupate.

Risks & Benefits

Risks include the potential for localized infestations and the emergence of adult biting fleas which can transmit diseases or parasites (like tapeworms) to pets and humans.
