Carpet beetle larvae feed on animal and plant substances such as wool, fur, feather, hair, seeds, grain, cereals, flour, dog and cat food, leather, dead insects and bird and rodent nests. The larvae live behind baseboards and moldings, in heating system air ducts, dresser drawers, carpets, clothing and furniture. Adult beetles fly in May and June. Four species are common in Maine, the three pictured below and the common carpet beetle, Anthrenus scrophulariae, which looks similar to both the furniture and varied carpet beetle.
