Carpet Beetle

The term "Carpet beetle" includes several species of Dermestid beetles that commonly feed on animal-based textile products. They average 2-5 mm long. 

Adults lay eggs on the larval food source, such as furs and woolen fabric or carpets. Eggs hatch in about 2 weeks and the larvae feed for varying periods, depending upon species and environmental conditions. When ready to pupate, the larvae may burrow further into the food or burrow elsewhere. 

These beetles will attack almost any animal-derived material including clothing, tapestries, woolen blankets, upholstered items, furs, feathers, down, pet foods, and even animals carcasses in attics, crawl spaces, and basements.
