Case-bearing Clothes Moth

Natural Habitat

Indoors in dark, undisturbed areas such as closets, attics, storage chests, and behind furniture. Infests natural fibers.

Diet & Feeding

Larvae feed on natural fibers, including wool, fur, feathers, silk, felt, and other animal products. They can also feed on cotton and synthetic fibers if blended with natural ones, or if soiled with food or perspiration.

Behavior Patterns

The most distinctive behavior of the larvae is their construction of a portable silken case, which they carry with them and enlarge as they grow. Adults are poor fliers and tend to run or hop; they are often found in dark areas. They are primarily active at night and are attracted to light but typically stay hidden.

Risks & Benefits

Potential risks include significant damage to textiles, clothing, carpets, and other items made of natural fibers. They do not bite or transmit diseases. There are no known benefits as they are considered pests in human environments.
