Carpet beetle larva

Natural Habitat

Indoors, especially in undisturbed areas like under furniture, rugs, in closets, and pantries. Outdoors, they can be found in nests of birds or insects, or on animal carcasses.

Diet & Feeding

Consumes a variety of organic materials, including wool, silk, fur, feathers, leather, pet food, stored food products (grains, cereals, spices), and insect remains.

Behavior Patterns

Larvae are typically slow-moving and prefer dark, undisturbed areas. They shed their skin (molt) multiple times as they grow, leaving behind characteristic hairy casings. Adults are attracted to light and often found near windows.

Risks & Benefits

Potential risks include damage to natural fibers (carpets, clothing, upholstery), museum specimens, and stored food products. Some people may also experience skin irritation from contact with their hairy larvae. They are generally considered pests indoors. Benefits are minimal in a domestic setting, but in nature, some species are detritivores, helping to break down organic matter.
