See this bug in the Encyclopedia

Natural Habitat

Typically found in dark, protected areas where pets sleep or rest, such as bedding, deep carpeting, cracks in floorboards, or upholstery. They avoid direct light.

Diet & Feeding

Scavengers that feed on organic debris, particularly 'flea dirt' (dried blood excreted by adult fleas), dead skin cells, and other organic matter found in dust.

Behavior Patterns

They are negatively phototactic (they move away from light) and actively burrow deep into carpet fibers or bedding. They spin a silken cocoon to pupate before emerging as adults.

Risks & Benefits

Risks: They are the precursor to biting adult fleas, which cause itching, allergic reactions, and can transmit tapeworms and diseases like typhus to pets and humans. Benefits: None.
