Carpet Beetle Larva (Shed skin or debris)
Scientific Name: Anthrenus verbasci (specifically the cast skin or exuviae)
Order & Family: Order: Coleoptera, Family: Dermestidae
Size: Larvae are typically 4-5 mm in length; the shed skins are similar in size.
Natural Habitat
Found indoors, typically in dark, secluded areas like closets, under furniture, in carpets, woolen fabrics, and collections of dried specimens.
Diet & Feeding
Larvae feed on natural fibers (wool, silk, fur, feathers), dried plant/animal products, dead insects, and pet hair.
Behavior Patterns
Larvae molt throughout their development, leaving behind hollow, translucent, hairy skins that look like the living insect. They shy away from light and move slowly.
Risks & Benefits
Risks: Larvae can cause significant damage to carpets, clothing, and upholstered furniture. The tiny hairs on shed skins can cause allergic dermatitis or skin irritation in some people (carpet beetle dermatitis). Benefits: They decompose dead organic matter in nature.
