Carpet Beetle Larva (most likely)

Natural Habitat

Indoors: particularly in dark, undisturbed areas such as under carpets, in closets, drawers, and attics. They feed on natural fibers, animal products, and stored foods.

Diet & Feeding

Animal-derived products, including wool, silk, feathers, fur, natural bristles, dried meat, dead insects, museum specimens, and sometimes synthetic fibers if soiled with food or perspiration.

Behavior Patterns

Larvae are the damaging stage, often found in hidden areas. They are slow-moving and prefer darker environments. They undergo complete metamorphosis (egg, larva, pupa, adult). Adult beetles are typically harmless and often found near windows as they are attracted to light.

Risks & Benefits

Risks: Significant pests of stored products and natural fiber textiles, causing damage to clothing, carpets, upholstered furniture, and museum collections. They can also occasionally cause skin irritation or allergic reactions in sensitive individuals due to their bristly hairs. Benefits: In nature, they act as scavengers, breaking down organic matter like dead animals and insects.
