Carpet Beetle Larva
Scientific Name: Anthrenus verbasci (typically for the Varied Carpet Beetle, but could be other Anthrenus species)
Order & Family: Order: Coleoptera (Beetles), Family: Dermestidae (Skin Beetles)
Size: 3 mm to 5 mm in length
Natural Habitat
Commonly found indoors in dark, undisturbed areas such as under furniture, in closets, behind baseboards, and in attics. They are attracted to natural fibers like wool, silk, and leather.
Diet & Feeding
They feed on natural animal fibers and organic debris, including wool, fur, silk, feathers, dead insects, pet hair, and lint. They do not eat synthetic fabrics unless they are soiled with food or sweat.
Behavior Patterns
The larvae avoid light and move slowly. This is the destructive stage of the insect's life cycle. They molt several times creating shed skins that can accumulate. Adults eventually emerge to feed on pollen and nectar outdoors but come inside to lay eggs.
Risks & Benefits
Risks: They are a major household pest that can damage clothing, carpets, upholstered furniture, and museum specimens. Some people may develop dermatitis or allergic reactions to the bristly hairs of the larvae. Benefits: In nature, they act as decomposers of dead organic matter.
