Dermestid beetles are in the family Dermestidae and order Coleoptera. These beetles are sometimes called larder beetles or carpet beetles. Adults range from 1 to 12 mm in length and have variable body coloration. In general, they are hairy, dark-colored, elongated, and have clubbed antennae. The larvae are light brown and can be up to 13 mm long. Many larvae have spines, called setae, on the back of the abdomen that are helpful with identification. Dermestid larvae and adults have chewing mouthparts.
