Natural Habitat

Indoors in dark, undisturbed areas such as closets, attics, storage chests, and behind furniture. They are found wherever natural fibers are present.

Diet & Feeding

Primarily feeds on natural fibers, including wool, fur, feathers, felt, pet hair, and lint. They can damage clothing, carpets, upholstered furniture, and stored textiles.

Behavior Patterns

Case-bearing clothes moth larvae build and carry a silk case, often incorporating fibers from their food source. They are secretive and avoid light, preferring dark, undisturbed areas. Adults are poor fliers and are attracted to light.

Risks & Benefits

Risks: Can cause significant damage to natural fiber textiles, leading to economic loss. Does not bite or transmit diseases. Benefits: None apparent directly to humans; in natural ecosystems, they act as decomposers of organic matter containing keratin.
