varied carpet beetle larvae

Anthrenus verbasci


The larval form of A. verbasci are roughly 4–5 millimetres (0.16–0.20 in) in length. The body is covered in a pattern of alternating light- and dark-brown stripes. The body is usually wider at the back than at the front and also bears 3 pairs of hair tufts along its rear abdomen that can be used for self-defense


The larvae of A. verbasci is a common household pest. Adult beetles usually lay their eggs in air ducts, in closets, under furniture, or under baseboards. Once hatched and until they pupate into adults, the larvae hide in dark, undisturbed areas and feed on organic material. The larvae are thus responsible for the damage of various items, such as furniture, clothing, blankets, furs, and carpets. Collections of specimens, especially of insects, are also vulnerable to attack, making A. verbasci a common pest in museums. Infestations can be prevented by regular vacuum cleaning, dry cleaning or airing clothing outside, placing naphthalene balls in closets, and removing abandoned bird and insect nests attached to the building. Signs of an infestation include the presence of damaged articles, molted larval skins in dark areas, and an abundance of adult beetles near windows. Deterring or killing A. verbasci can be accomplished using insecticides, oxygen deprivation, freezing, and pheromone and scent traps.


The varied carpet beetle (Anthrenus verbasci) is a 3 mm–long beetle that can be a serious household pest. It feeds on natural fibers and can damage carpets, furniture and clothing. The larval form is known as a woolly bear, a name it shares with the larvae of Arctia caja and many other moths of the family Arctiidae (over the years i have seen several specimen from this little creatures, but always only the larvae)
