Carpet Beetle Larva (Anthrenus species likely)

Natural Habitat

Indoors, commonly found in homes, museums, warehouses. Prefers dark, undisturbed areas like under carpets, in closets, behind baseboards, and within upholstered furniture. Also found in nests of birds and mammals.

Diet & Feeding

Keratin-rich materials such as wool, silk, feathers, fur, leather, animal bristles, dead insects, pet hair, and occasionally synthetic fibers contaminated with protein. They are scavengers.

Behavior Patterns

Larvae are the damaging stage, often moving slowly and remaining hidden. They are sensitive to light and will retreat to dark areas. They molt several times, leaving behind shed skins covered in bristles, which can be mistaken for live insects. Adults are typically outdoor pollinators, feeding on nectar and pollen.

Risks & Benefits

Potential risks include significant damage to textiles, clothing, carpets, upholstered furniture, and museum collections. Some people may develop allergic reactions (dermatitis or respiratory issues) to their bristles. They are generally not considered beneficial in human dwellings, but in natural environments, they contribute to decomposition.
