Case-making Clothes Moth

Natural Habitat

Commonly found indoors in dark, undisturbed areas where natural fibers are stored, such as closets, attics, storage chests, and behind furniture. Infestations often occur in infrequently used garments, carpets, tapestries, or upholstered furniture.

Diet & Feeding

The larvae of case-making clothes moths feed on natural fibers, particularly those of animal origin such as wool, silk, fur, feathers, and felt. They can also feed on blended fabrics and sometimes on stored food products if suitable natural fibers are present.

Behavior Patterns

Case-making clothes moths are known for the silken case they spin around themselves, which they carry with them as they feed and grow. The larvae are sluggish and often feed in concealed locations. Adults are poor fliers and tend to flutter rather than fly purposefully. They are attracted to dark, undisturbed areas where they can lay eggs on suitable food sources.

Risks & Benefits

Risks: Case-making clothes moths are significant household pests, causing damage to clothing, carpets, and other textile items made of natural fibers. They do not bite or transmit diseases to humans. Benefits: None in a household pest context; in nature, moths contribute to the food chain and decomposition of natural materials.
