Flea Larva (possibly dried/desiccated)

Scientific Name: Ctenocephalides felis (most likely common cat flea) or Ctenocephalides canis

Order & Family: Order: Siphonaptera, Family: Pulicidae

Size: 2mm to 5mm in length (larval stage)

Flea Larva (possibly dried/desiccated)

Natural Habitat

Typically found in areas where pets rest (pet beds, carpets, cracks in hardwood floors). They prefer dark, somewhat humid environments away from direct sunlight.

Diet & Feeding

Flea larvae are detritivores. They feed on organic debris found in carpets and bedding, but their most critical food source is 'flea dirt' (dried blood excreted by adult fleas).

Behavior Patterns

Larvae are negatively phototactic (they avoid light). Upon hatching, they burrow deep into carpet fibers or floor cracks to find food and moisture. This specimen appears to be curled, which is common when they desiccate (dry out) or die.

Risks & Benefits

Risks: They mature into adult fleas that bite mammals (including humans) to feed on blood, causing itching, allergic dermatitis, and potentially transmitting parasites like tapeworms. There are no ecological benefits in a domestic setting.
