Carpet beetle (larva)

Natural Habitat

Carpet beetle larvae are typically found in dark, undisturbed areas where they can feed on natural fibers. This includes carpets, rugs, upholstered furniture, clothing made of wool, silk, or fur, stored foods, and sometimes even in insect collections or taxidermy. They are often found indoors.

Diet & Feeding

They are scavengers that feed on a wide variety of animal products, including wool, fur, feathers, silk, leather, dried meat, dead insects, pet dander, and other natural fibers containing keratin or protein.

Behavior Patterns

Carpet beetle larvae are slow-moving and avoid light. They feed continuously for several weeks or months, molting multiple times. The larval stage is the damaging stage. They often curl up or play dead when disturbed. Adults feed on pollen and nectar and are often found outdoors or near windows.

Risks & Benefits

Potential risks include damage to household items made of natural fibers such as clothing, carpets, and upholstered furniture. They can also contaminate food products. Some people may experience allergic reactions or skin irritation from contact with their bristles, though this is less common than damage to property. They offer little to no direct benefits in a household setting, though in nature, they play a role as decomposers.
