Carpet Beetle
Dermestes spp. (e.g., Anthrenus verbasci - Varied Carpet Beetle, Attagenus unicolor - Black Carpet Beetle)
- Order & Family
- Coleoptera (Beetles), Dermestidae (Skin Beetles)
- Size
- Adults typically range from 2-5 mm in length; larvae can be slightly larger.
Natural Habitat
Indoors, larvae are found in carpets, rugs, upholstered furniture, clothing, and stored food products. Outdoors, they can be found in bird nests, animal carcasses, and dried plants.
Diet & Feeding
Larvae feed on a variety of animal-derived products, including wool, silk, fur, feathers, leather, pet food, and dead insects. Adults primarily feed on pollen and nectar.
Behavior Patterns
Carpet beetle larvae primarily feed on natural fibers in dark, undisturbed areas. Adults are attracted to light and are often found near windows. They undergo complete metamorphosis with egg, larva, pupa, and adult stages. Larvae are known to shed their skins multiple times as they grow.
Risks & Benefits
Risks include damage to natural fiber products (carpets, clothing, furniture) and potential allergic reactions (dermatitis) to larval hairs for sensitive individuals. They can also contaminate dried food products. Benefits include their role as scavengers in nature, helping to break down organic matter.
