The adults are small (1/16 to 1/8-inch), oval-shaped beetles ranging in color from black- to various 'mottled' patterns of white, brown, yellow and orange. Adult carpet beetles feed on flower pollen and do not damage woolens and other fabrics.
They are a common species, often considered a pest of domestic houses and, particularly, natural history museums, where the larvae may damage natural fibers and can damage carpets, furniture and clothing.
Adult beetles usually lay their eggs in air ducts, in closets, under furniture, or under baseboards. Once hatched and until they pupate into adults, the larvae hide in dark, undisturbed areas and feed on organic material.
