Natural Habitat

Indoors, especially in areas with natural fibers like wool, silk, fur, felt, and feathers. Can be found in closets, attics, storage areas, and under furniture.

Diet & Feeding

Keratin-containing materials, including wool, fur, feathers, silk, felt, upholstered furniture, and carpets. They can also feed on lint, dust, and human hair.

Behavior Patterns

Larvae construct a portable silken case incorporating fibers from their food source. They carry this case with them as they feed and grow. They are slow-moving and prefer dark, undisturbed areas. Adults are poor flyers and are often seen scurrying rather than flying. The larval stage is the damaging stage.

Risks & Benefits

Potential Risks: Significant damage to natural fiber textiles, clothing, carpets, and fur. Can cause considerable economic loss by destroying valuable items. They do not bite or sting humans. Potential Benefits: None known for humans; they are generally considered pests due to their destructive feeding habits.
