Case-bearing Clothes Moth

Natural Habitat

Indoors, especially in undisturbed areas like closets, attics, and storage areas. Larvae create a silk case and carry it with them.

Diet & Feeding

Larvae feed on natural animal fibers like wool, fur, feathers, silk, felt, and sometimes blends containing these materials. Adults do not feed.

Behavior Patterns

Adults are weak fliers and prefer darkness. They are often found scurrying. They lay eggs on suitable food sources. Larvae build and live within a silk case covered with bits of the material they are eating; they drag this case with them as they move and feed. The pupa also develops inside this case.

Risks & Benefits

Risks: Can cause significant damage to clothing, carpets, upholstery, and stored textiles made of animal fibers. Benefits: No known direct benefits to humans or the ecosystem, primarily considered a pest in human environments.
