Carpet Beetle Larva

Natural Habitat

Indoors, commonly found in undisturbed areas like carpets, rugs, woolen items, upholstered furniture, attics, and around baseboards where dust and lint accumulate. Can also be found in pantries feeding on dry goods.

Diet & Feeding

Keratin-based materials (wool, silk, feathers, leather, fur), natural fibers, dried plant products, pet food, crumbs, and sometimes dead insects.

Behavior Patterns

Larvae are scavenging pests, moving slowly and often preferring dark, undisturbed areas. They are known for 'grazing' on surfaces, causing damage to textiles. The larval stage can last for several months, and they shed their skins multiple times, leaving behind 'cast skins' which are often more noticeable than the larvae themselves. Adults are small, oval beetles that are attracted to light and often found near windows during warmer months.

Risks & Benefits

Risks: Primarily a household pest, causing damage to natural fibers in carpets, clothing, and other textiles. They can also infest dried food products. Does not bite or spread disease to humans. Benefits: In nature, they are detritivores, playing a role in breaking down organic matter like animal remains and discarded plant material.
