Natural Habitat

Indoors, especially dark, warm, humid areas such as cupboards, attics, pantries, and wall voids; also found in bird or rodent nests.

Diet & Feeding

Larvae feed on dried plant and animal materials, including wool, feathers, hair, grain, seeds, and moldy organic debris. Adults generally do not feed or consume only liquids.

Behavior Patterns

Adults are nocturnal and weak fliers, often resting on walls near infested materials. Larvae spin silken cases or galleries and can persist for months in undisturbed areas.

Risks & Benefits

Larvae may damage woolens, stored food, textiles, and taxidermy materials, though infestations are usually minor. They recycle organic debris and serve as prey for spiders and parasitoids.
