The adult carpet beetle is small (about 1/8 inch long), and has a varied color pattern. The larvae are about ¼ inch long, light brown and with long brown hairs extending from the sides and tail end. Irregular holes in carpets, blankets, and clothing is caused by the larval feeding.

(Attagenus spp.) The larvae of carpet beetles feed on products of animal origin, including wool, leather, and fur. The larvae of some species feed on stored food. Adults usually live outdoors and feed on the nectar and pollen of plants. The larvae may require 2-3 months to complete development and during this time may shed their skin several times. They may move around the house seeking new feeding sites.
