Webbing clothes moths spin a silken web to form feeding tubes that they attach to the item being eaten. As they mature, they shed their skins, which look like living larvae. Carpet beetles crawl from place to place as they eat, but may be found in areas that do not provide any food. Fecal pellets are found where beetles have been feeding. The life cycle of the carpet beetle.
Carpet beetles undergo complete metamorphosis.
The adult lives 20 to 60 days and lays 30 to 100 eggs, which hatch in 6 to 20 days. The larva lasts 60 to 325 days. Both the larval and adult stages damage fabric. Clothes moth and carpet beetle larvae feed in quiet, dark areas closets, attics, bureau drawers, storage trunks or boxes. Items that are stored for long periods are especially at risk.
