The four most important and most common species are the black carpet beetle (Attagenus mezatoma) shown here, the varied carpet beetle (Anthrenus verbasci) , the common carpet beetle (Anthrenus scrophulariae) , and the furniture beetle (Anthrenus flavipes). The adults feed primarily on pollen and nectar and can be found on outdoor plants during the summer. The adult stages of carpet beetles are small, oval insects, usually less than 1/4 inch long. Carpet beetle larvae are usually about the size of the adult beetle, 1/4 inch or less in length but they have dense tufts of long setae (bristles) on their bodies. Black carpet beetle larvae have a long tuft of hair at the end of their bodies. Adult carpet beetles are commonly found indoors at windows. Carpet beetle larvae often wander about the infested location-- from room to room in a house. This behavior results in spreading the infestation throughout the house. Coleoptera: Dermestidae.
