Carpet Beetle Larva (possibly Black Carpet Beetle or Varied Carpet Beetle)

Natural Habitat

Indoors, especially in undisturbed areas under carpets, rugs, upholstered furniture, in closets, pantries, and attics. They feed on natural fibers.

Diet & Feeding

Keratin-based products (wool, silk, fur, feathers), dried animal products, stored dry goods, dead insects (e.g., in insect collections), and sometimes synthetic fibers if soiled with food.

Behavior Patterns

Larvae are typically slow-moving and avoid light. They feed voraciously on a variety of organic materials. They can be found in groups or individually. The image shows a larva, which is the destructive stage. Adults are active flyers and feed on pollen and nectar outdoors.

Risks & Benefits

Potential risks: Significant pests of stored products and natural fiber textiles, causing damage to clothing, carpets, furniture, and insect collections. They do not bite or sting humans, but some people may experience allergic reactions to their shed skin or hairs. Benefits: In nature, they are detritivores, helping to break down organic matter like animal carcasses and insect remains.
