Varied Carpet Beetle
Anthrenus verbasci
- Order & Family
- Order: Coleoptera, Family: Dermestidae
- Size
- Adults typically range from 2 to 3.5 mm (0.08 to 0.14 inches) in length. Larvae can be up to 5 mm (0.2 inches) long.
Natural Habitat
Indoors, they are commonly found in homes, museums, and warehouses, particularly in areas with natural fibers or animal products. Outdoors, adults can be found on flowering plants.
Diet & Feeding
Larvae feed on a wide variety of animal products, including wool, silk, leather, fur, feathers, pet hair, dead insects, museum specimens, and even some dried foods. They are also known to consume natural fibers in carpets, clothing, upholstery, and stored foods. Adults feed on pollen and nectar, often found on outdoor flowers in spring and summer.
Behavior Patterns
Adult carpet beetles are often found near windows as they are attracted to light, or on flowering plants where they feed on pollen and nectar. Larvae are typically found in dark, undisturbed areas where their food sources (keratin-based materials) are abundant, such as under furniture, in closets, or in air ducts. The larvae are the destructive stage, causing damage to natural fibers. They are typically slow-moving.
Risks & Benefits
Risks: Varied carpet beetles are significant household pests. Their larvae can cause considerable damage to natural fiber products such as wool carpets, clothing, furniture, furs, and stored food items. They can also infest museum collections and taxidermy. While they do not bite humans, some individuals may experience skin irritation from contact with the larval hairs. Benefits: In nature, they play a role in decomposition, feeding on dead animals and insects.
