Carpet beetle (likely varied carpet beetle or black carpet beetle)
Anthrenus verbasci (varied carpet beetle) or Attagenus unicolor (black carpet beetle)
- Order & Family
- Coleoptera, Dermestidae
- Size
- 2-5 mm (adults), larvae can be slightly larger
Natural Habitat
Indoors, commonly found in homes, museums, warehouses, and other structures where suitable food sources are available. Outdoors, they can be found in bird nests, animal carcasses, and dried plant matter.
Diet & Feeding
Larvae feed on natural fibers such as wool, silk, fur, feathers, leather, dried animal products, stored dry foods, and insect collections. Adult beetles typically feed on pollen and nectar outdoors.
Behavior Patterns
Carpet beetles undergo complete metamorphosis (egg, larva, pupa, adult). The larvae are the destructive stage, causing damage to fabrics and other materials. They are often found in dark, undisturbed areas. Adults are attracted to light and may be seen near windows. They are slow-moving and generally play dead when disturbed.
Risks & Benefits
Risks: Can cause significant damage to household items, clothing, carpets, and museum specimens made of natural fibers. They do not bite or transmit diseases, but skin contact with larval hairs can cause allergic reactions in some individuals. Benefits: In nature, they act as scavengers, breaking down organic materials, but indoors, they are considered pests.
