Carpet Beetle (likely Varied Carpet Beetle or Black Carpet Beetle)

Natural Habitat

Indoors, commonly found in homes on carpets, rugs, upholstered furniture, clothing, museums, attics, and often near natural fibers or stored food products. Outdoors, they can be found in nests of birds, rodents, and insects.

Diet & Feeding

Larvae feed on a wide variety of animal and plant products, including wool, silk, fur, feathers, leather, dried meat, dried fish, pet food, stored grains, and dead insects. Adults primarily feed on pollen and nectar from flowers outdoors.

Behavior Patterns

Larvae are the damaging stage, causing irregular holes in fabrics. They prefer dark, undisturbed areas. Adults are winged and often fly to lights or windows. They undergo complete metamorphosis (egg, larva, pupa, adult). Females lay eggs in suitable larval food sources. They can be found year-round indoors.

Risks & Benefits

Risks: Can cause significant damage to natural fiber textiles, stored food products, and museum collections. Some people may experience allergic reactions to larval hairs. Benefits: In nature, they play a role as scavengers, breaking down organic matter like dead insects and animal remains. However, their presence indoors is generally considered a pest.
