Carpet Beetle (Larva)

Natural Habitat

Indoors, commonly found in homes, museums, and warehouses. They prefer dark, undisturbed areas such as under carpets, in closets, pantries, and behind baseboards, feeding on natural fibers and dried animal products.

Diet & Feeding

Keratin-containing materials (wool, silk, leather, feathers), dried animal products (pet food, dead insects, museum specimens), and some plant-based materials (cereals, spices).

Behavior Patterns

Larvae are slow-moving and tend to avoid light. They feed secretly, often causing damage before they are noticed. They undergo several molts as they grow. Adults are typically attracted to light and are often found near windows, but they do not cause damage; they feed on nectar and pollen.

Risks & Benefits

Risks: Can cause significant damage to natural fiber textiles (carpets, clothing, upholstery), museum specimens, and stored dry goods. Some people may experience skin irritation from their bristly larval hairs. Benefits: In nature, they are detritivores, playing a role in decomposition, though this is less recognized in an indoor pest context.
