Flea larva

Inhabits dark, protected areas such as carpets, upholstery, pet bedding, and floor cracks where humidity is high.

Scavengers that feed on organic debris, skin scales, and most importantly, 'flea dirt' (dried blood excreted by adult fleas).

Legless and worm-like, they are photophobic (avoid light) and tactilely sensitive, burrowing deep into fibers or carpet to stay hidden while developing through three larval instars.

While larvae do not bite humans, their presence indicates a flea infestation. If they reach adulthood, they become parasites that cause irritation, allergic dermatitis, and can transmit diseases like tapeworms or plague.
