Case-bearing clothes moth (larva)

Natural Habitat

Indoors, commonly found in closets, drawers, or storage areas where natural fibers are present.

Diet & Feeding

Larvae feed on keratin-containing animal products such as wool, fur, feathers, hair, felt, and silk.

Behavior Patterns

Larvae construct a portable silken case incorporating surrounding fibers for camouflage. They drag this case with them as they feed and eventually pupate inside it.

Risks & Benefits

This is a significant household pest that causes physical damage to clothing, upholstery, and carpets. They lack benefits to human environments and can be difficult to eradicate once established.
