Carpet beetle

Natural Habitat

Indoors, commonly found in homes, museums, and warehouses where they feed on natural fibers, animal products, and dry food.

Diet & Feeding

Larvae feed on natural fibers such as wool, silk, fur, feathers, leather, pet hair, dried animal remains, and sometimes dry food products. Adult carpet beetles feed on pollen and nectar outdoors but do not feed on household items.

Behavior Patterns

The most damaging stage is the larval stage, which feeds and causes damage. Larvae are typically slow-moving and covered in bristles. Adults are attracted to light and often found near windows. They undergo complete metamorphosis.

Risks & Benefits

Potential risks include damage to clothing, carpets, upholstery, and stored foods. Some people may experience skin irritation or allergic reactions from bristles shed by the larvae. No known significant benefits in a household setting, though outdoors they can act as scavengers.
