Natural Habitat

Found in dark, protected areas where pets sleep, such as carpet fibers, floor cracks, bedding, or soil.

Diet & Feeding

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

Behavior Patterns

Larvae are photophobic (avoid light) and seek high humidity. They progress through three larval stages before spinning a cocoon to pupate.

Risks & Benefits

Indicates an active flea infestation. While larvae do not bite humans or pets, they develop into biting adults that can transmit diseases and cause dermatitis.
