Carpet Beetle Larva

Natural Habitat

Often found indoors in dark, undisturbed areas such as closets, carpet edges, under furniture, attic insulation, and storage boxes. Outdoors, they inhabit bird nests and wasp nests.

Diet & Feeding

The larvae feed on keratin-containing fibers and dry animal products such as wool, fur, silk, leather, pet hair, feathers, dead insects, and dried plant products. They digest keratin.

Behavior Patterns

Larvae prefer dark, secluded places and move slowly. They shed their skin multiple times as they grow, leaving behind brownish, shell-like cast skins. When disturbed, they may play dead or curl up. They are often spotted climbing walls or on fabrics.

Risks & Benefits

Risks: They are a common household pest that can cause significant damage to carpets, clothing, upholstery, and taxidermy. The bristle-like hairs on the larvae can cause skin irritation or dermatitis (carpet beetle dermatitis) in sensitive individuals. Benefits: In nature, they act as decomposers, breaking down dead organic matter.
