Natural Habitat

Found worldwide, commonly indoors in homes, museums, and warehouses. They thrive in dark, undisturbed areas like closets, attics, under rugs, and in air ducts.

Diet & Feeding

Larvae feed on keratin-based natural fibers such as wool, silk, fur, feathers, hair, and leather, as well as dead insects and dried food products (grains, pet food). Adults feed mostly on pollen and nectar.

Behavior Patterns

Adults are attracted to light and are often found near windows. However, the damaging larvae are photophobic (avoid light) and hide deep in fabrics or crevices. This beetle undergoes complete metamorphosis.

Risks & Benefits

Risks: Larvae are destructive pests that damage clothing, carpets, upholstered furniture, and museum specimens. Some people may develop allergic reactions (dermatitis) from the larvae's bristly hairs. Benefits: In nature, they help decompose dead animal matter.
