Carpet Beetle Larva

Natural Habitat

Typically found indoors in dark, undisturbed areas such as closets, carpet edges, under furniture, in air ducts, or stored woolens. Outdoors, they inhabit bird nests and bee hives.

Diet & Feeding

Larvae feed on natural fibers and protein-based materials including wool, silk, fur, feathers, leather, dead insects, pet hair, and dried plant products.

Behavior Patterns

The larvae avoid light and move slowly. They are known for their 'fuzzy' appearance due to stiff hairs (setae). When disturbed, they may curl up or play dead. They undergo complete metamorphosis.

Risks & Benefits

Risks: Major household pest that damages carpets, clothing (especially wool), upholstery, and museum specimens. They do not bite or spread disease, but their tiny hairs can cause allergic skin reactions (carpet beetle dermatitis) in some people. Benefits: In nature, they act as decomposers of dead animal matter.
