Carpet Beetle (likely Varied Carpet Beetle or Black Carpet Beetle larva)
Anthrenus verbasci (Varied Carpet Beetle) or Attagenus unicolor (Black Carpet Beetle)
- Order & Family
- Order: Coleoptera, Family: Dermestidae
- Size
- Larvae typically 2.5-5 mm (0.1-0.2 inches) long.
Natural Habitat
Indoors, commonly found in homes, museums, and warehouses. Outdoors, they can be found in nests of birds, rodents, and insects, as well as on carrion or dried plants.
Diet & Feeding
The larvae are scavengers, feeding on a wide variety of organic materials including wool, silk, feathers, leather, fur, pet hair, dead insects, museum specimens, and sometimes dried foods like cereal or pet food.
Behavior Patterns
Carpet beetle larvae are typically slow-moving and prefer dark, undisturbed areas. They are known for their destructive feeding habits for natural fibers. Adults feed on pollen and nectar and are found outdoors, entering homes through openings in search of egg-laying sites. They go through complete metamorphosis (egg, larva, pupa, adult).
Risks & Benefits
Risks: Significant pests of stored products and natural fibers, causing damage to clothing, carpets, upholstery, and museum collections. They do not bite humans but can cause allergic reactions (dermatitis) in some sensitive individuals due to their shed hairs. Benefits: In nature, they play a role in decomposition by consuming animal remains and dried organic matter.
