Carpet Beetle Larva
Scientific Name: Anthrenus verbasci (typically for the Varied Carpet Beetle, a common household species)
Order & Family: Order: Coleoptera (Beetles), Family: Dermestidae (Skin Beetles)
Size: Larvae grow up to 4-5 mm (about 3/16 inch) in length.
Natural Habitat
Typically found indoors in dark, undisturbed areas such as under carpets, in closets, behind loose baseboards, and in stored natural fabric materials. Outdoors, they occupy bird nests or animal dens.
Diet & Feeding
Larvae feed on natural animal fibers and organic debris, including wool, silk, fur, feathers, hair, dead insects, pet dander, and dry food products.
Behavior Patterns
The larvae avoid light and move slowly, often found feeding on the surface of fabrics or burrowing into materials. They leave behind shed skins (molts) which are often mistaken for the live insect. The adult beetles are attracted to light and feed on pollen.
Risks & Benefits
Risks: Major household pest; larvae can cause significant damage to carpets, clothing, upholstery, and taxidermy. Some people may experience allergic skin reactions (dermatitis) upon contact with the larva's bristly hairs. Benefits: In nature, they act as decomposers, breaking down dead animal matter.
