The most common carpet beetles are the varied (Anthrenus verbasci) and black (Attagenus megatoma). The adults of both are oval-shaped and 1/8-3/16 inch long. The larvae of both are about 1/4 inch long, elongated and oval, with shorter brownish or black bristles, arranged more in a fan-like position on each side. The carpet beetle is also called the old-fashioned C.B. or “buffalo bug.” The female lays about 100 soft, white eggs in clothing, furniture, cracks, and other concealed places. Eggs will hatch in 8 to 15 days in summer and linger in cool weather. The black carpet beetle will normally have one generation per year while the other carpet beetles have up to four per year.
