Carpet Beetle (larva)

Natural Habitat

Indoors, especially in areas with natural fibers like carpets, rugs, upholstered furniture, woolens, furs, and pet hair. Also found in attics, wall voids, and sometimes nests of birds or insects.

Diet & Feeding

Keratin-rich materials such as wool, silk, fur, feathers, leather, dead insects, pet dander, and occasionally stored food products.

Behavior Patterns

Larvae are the damaging stage, often found in dark, undisturbed areas. They are slow-moving and tend to roll up when disturbed. Adults are winged and are attracted to light, often found near windows; they feed on pollen and nectar outdoors.

Risks & Benefits

Risks: Can cause significant damage to household goods made of natural fibers, including clothing, carpets, and museum specimens. Some people may develop skin irritations or allergic reactions from bristles shed by larvae. Benefits: Play a role in decomposition in natural environments, but are primarily considered pests in household settings.
