Carpet Beetle
Dermestidae (various genera and species, e.g., Anthrenus, Trogoderma)
- Order & Family
- Order: Coleoptera, Family: Dermestidae
- Size
- Adults typically range from 2 to 5 mm (0.08 to 0.2 inches) in length. Larvae can be slightly larger.
Natural Habitat
Indoors, carpet beetles are found in undisturbed areas like closets, attics, under furniture, and in air ducts, especially where natural fibers or dried animal products are stored. Outdoors, adults are common on flowering plants.
Diet & Feeding
Larvae feed on a wide variety of natural fibers including wool, silk, feathers, fur, hair, and dried animal products. They can also consume stored food products, such as cereals and pet food. Adult carpet beetles feed on pollen and nectar from outdoor plants.
Behavior Patterns
Carpet beetles undergo complete metamorphosis, meaning they have egg, larva, pupa, and adult stages. The larval stage is responsible for most of the damage, as they feed on organic materials. Adults are typically found outdoors and are attracted to light, or indoors near windows. Larvae prefer undisturbed, dark areas.
Risks & Benefits
Risks: Carpet beetles are significant household pests, causing damage to carpets, clothing, upholstered furniture, and stored food items. Some people may experience skin irritation or allergic reactions from contact with carpet beetle larvae hairs. Benefits: In nature, they play a role in decomposition, breaking down organic matter.
