Case-Bearing Clothes Moth

Natural Habitat

Indoors, particularly in dark, undisturbed areas where natural fibers are stored, such as closets, attics, storage chests, and under furniture. They prefer humid conditions but can tolerate dry environments.

Diet & Feeding

Larvae primarily feed on natural fibers, including wool, silk, fur, feathers, and other animal products. They can also consume synthetic blends if natural fibers are present. Adults do not feed.

Behavior Patterns

Case-bearing clothes moths are known for their larvae building a silk case that they carry around and enlarge as they grow. The larvae are the destructive stage, feeding on natural fibers. Adults are not destructive as they do not feed; their sole purpose is reproduction. They are typically nocturnal or active in dim light and are poor fliers, often seen crawling or making short flights.

Risks & Benefits

Potential Risks: Significant pest of textiles, causing damage to clothing, carpets, upholstery, and stored items made of natural fibers. They do not bite humans or transmit diseases. Benefits: None significant in a domestic setting; in natural ecosystems, they play a minor role in decomposition of animal remains.
