Black carpet beetle

The black carpet beetle is a common dermestid beetle species, scientifically known as Attagenus unicolor.

The black carpet beetle (Attagenus unicolor) is a common dermestid beetle species found throughout North America, including Canada. Its larvae are household pests that feed on natural materials such as wool, fur, feathers, leather, and other keratin-containing products, causing damage to carpets, clothing, and stored goods.

Description

Black carpet beetles are small, oval beetles with adults measuring about 3–5 mm in length. The larval stage is the one most often associated with damage to household materials.

Habitat and distribution

The species occurs across North America, including the United States, Canada, and Mexico. It is commonly found indoors in closets, cupboards, carpets, and other areas where suitable food sources are present.

Feeding and damage

Adults feed on pollen and other plant material, but larvae feed on animal-derived substances such as wool, silk, fur, feathers, hair, and leather. They can also feed on dried insects, dried meat, and some stored plant products, including grains, flour, and cereals.

Control and prevention

Prevention focuses on sanitation, vacuuming, removing lint and hair, and protecting stored textiles. Heat treatments such as hot laundering or drying can kill eggs and larvae.
