Carpet Beetle Larva

Natural Habitat

Commonly found indoors in homes, specifically under baseboards, in carpets, closets, upholstered furniture, and air ducts where organic debris accumulates.

Diet & Feeding

Larvae feed on natural animal fibers and products including wool, silk, fur, feathers, leather, and dead insects; they are scavengers of keratin and chitin.

Behavior Patterns

Larvae are photophobic (avoid light) and prefer dark, secluded areas. They undergo a long larval period (often months to a year) and can survive for substantial periods without food.

Risks & Benefits

They are a significant pest that can damage household textiles and stored goods. Their stiff hairs (setae) can cause skin irritation or 'carpet beetle dermatitis' in sensitive individuals, which is often mistaken for bed bug bites.
