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

Natural Habitat

Indoors, commonly found in homes, museums, warehouses, and other structures where animal products (wool, fur, feathers, leather, dried food) are stored or present. They often inhabit cracks, crevices, under carpets, in closets, and pantries.

Diet & Feeding

Larvae are scavengers that feed on a wide variety of animal and plant products, including natural fibers (wool, silk, fur, feathers, leather), dried meat, pet food, cereals, museum specimens, dead insects, and lint. Adults primarily feed on pollen and nectar outdoors but do not feed on household items.

Behavior Patterns

Adult carpet beetles are often attracted to light and may be found near windows. Larvae are typically found in dark, undisturbed areas where their food sources are abundant. They are known for remaining hidden and can cause significant damage before their presence is noticed. Females lay eggs in clusters on food sources. The larval stage is the most damaging, as it is when they feed and grow. They have multiple instars and shed their skins, leaving behind distinctive empty casings. The life cycle can range from several months to a year, depending on conditions.

Risks & Benefits

Risks: Carpet beetles are significant household pests, causing damage to textiles, clothing, carpets, furniture, and stored food products. While they do not bite humans, some people may experience skin irritation or allergic reactions from contact with their shed larval skins or hairs. Benefits: In nature, dermestid beetles play a role as decomposers, breaking down organic matter, including dead animals.
