Carpet Beetle (larva)

Natural Habitat

Indoors, especially in undisturbed areas where food sources (fibers, animal products) are present: carpets, rugs, upholstered furniture, closets, attics, museums, and food storage areas.

Diet & Feeding

Keratin-containing materials (wool, silk, leather, feathers, furs), animal products (dried meat, pet food), dried plants, and stored food products. They do not feed on synthetic fibers.

Behavior Patterns

Larvae are the damaging stage, feeding on natural fibers and animal products. They are often found in dark, undisturbed places. Adults are typically attracted to light and are often found near windows. The larvae are slow-moving and often curl up when disturbed. They undergo complete metamorphosis.

Risks & Benefits

Risks: Can cause significant damage to natural fiber textiles, carpets, clothing, museum specimens, and stored foods. Some people may experience skin irritation or allergic reactions from bristles shed by larvae. Benefits: In nature, some species play a role as scavengers, breaking down organic materials. However, indoors, they are considered pests.
