Carpet Beetle Larva

Natural Habitat

Found indoors in homes, warehouses, and museums, typically in dark, undisturbed areas such as under carpets, in closets, or within upholstered furniture.

Diet & Feeding

Scavengers that feed on natural fibers and animal products including wool, silk, fur, feathers, hair, dead insects, and dried pet food.

Behavior Patterns

The larvae are slowly moving and avoid light. They undergo a complete metamorphosis (egg, larva, pupa, adult). The larval stage is the most destructive, lasting from several months to a year depending on food availability and temperature.

Risks & Benefits

They do not bite or transmit disease, but they are common household pests that damage clothing and textiles. Some people may experience 'carpet beetle dermatitis,' an allergic reaction to the larval hairs (setae) which can cause itchy welts or raspy skin.
