Case-bearing Clothes Moth

Natural Habitat

Indoors, in undisturbed areas such as closets, attics, storage areas, and under furniture where natural fibers are present. They are often found on or under rugs, carpets, and upholstered furniture.

Diet & Feeding

Larvae feed on natural fibers such as wool, fur, silk, feathers, and felt. They can also infest animal products like hair, lint, and dust, particularly if soiled with perspiration or food.

Behavior Patterns

Case-bearing clothes moth larvae construct and live within a silken case, which they enlarge as they grow. They drag this case with them wherever they go. They typically prefer dark, undisturbed areas. Adults are poor fliers and are attracted to lights.

Risks & Benefits

Risks: Can cause significant damage to clothing, carpets, upholstered furniture, and other items made of natural fibers. They do not bite or transmit diseases. Benefits: None significant in a domestic setting; in nature, they contribute to decomposition of animal products.
