Black Carpet Beetle

Natural Habitat

Commonly found indoors in homes, warehouses, and museums. Larvae live in dark, secluded places such as under carpets, in closets, or within upholstered furniture. Adults are often found near windows, as they are attracted to light.

Diet & Feeding

The larvae feed on natural fibers like wool, silk, fur, feathers, and leather, as well as dead insects, pet hair, and stored food products (e.g., cereals, flour). Adult beetles primarily feed on flower pollen and nectar outdoors.

Behavior Patterns

Adults are active in spring and early summer and are good fliers, often entering homes from outdoors. Females lay eggs in suitable larval food sources. The larval stage is responsible for all the damage. Larvae are slow-moving, avoid light, and can live for several months to over a year depending on conditions.

Risks & Benefits

Risks: A common and destructive household pest. Larvae can cause significant damage to carpets, clothing, upholstery, and other items made of animal-based materials. The bristly hairs shed by the larvae can also cause allergic reactions or skin irritation in some individuals. Benefits: In nature, they act as decomposers, cleaning up carcasses and other organic debris.
