Carpet Beetle
Scientific Name: Dermestes lardarius (Larder Beetle is commonly confused but is different), Anthrenus verbasci (Varied Carpet Beetle), Attagenus unicolor (Black Carpet Beetle), Trogoderma variabile (Warehouse Beetle) are common species.
Order & Family: Order: Coleoptera, Family: Dermestidae
Size: Larvae range from 1 mm to 5 mm depending on species and developmental stage. Adults are typically 2 mm to 5 mm in length.
Natural Habitat
Indoors, they are commonly found in carpets, rugs, upholstered furniture, clothing, blankets, and stored natural fiber items. Also found in attics, vents, and wall voids where animal nests or dead insects may be present. Outdoors, adults are found on flowering plants.
Diet & Feeding
Larvae feed on natural fibers such as wool, silk, fur, feathers, leather, and sometimes synthetic fibers if mixed with natural ones. They also consume pet hair, lint, and dead insects. Adult carpet beetles typically feed on pollen and nectar outdoors.
Behavior Patterns
Carpet beetles undergo complete metamorphosis with four life stages: egg, larva, pupa, and adult. The larval stage is responsible for most of the damage as they feed on natural fibers. They are often found in dark, undisturbed areas. Adults are winged and can fly, often found near windows as they are attracted to light.
Risks & Benefits
Risks: Carpet beetles can be significant indoor pests, causing damage to textiles, clothing, and other natural fiber products. Some people may develop allergic reactions or skin irritation from contact with larval hairs. Benefits: In nature, they play a role in decomposition by consuming animal remains and shed fur/feathers.
