Tinea pellionella (Case-bearing clothes moth)

Indoors in homes, warehouses, and locations containing animal-based textiles, as well as bird nests outdoors.

Larvae consume keratin-based materials such as wool, fur, feathers, hair, and silk, as well as some stored spice products.

Larvae live inside a portable silken case they build and carry with them, incorporating fibers from their food source. They are most active in dark, undisturbed areas.

Risks: Significant pest that causes permanent damage to clothing, upholstery, and carpets. Benefits: Minimal, though they contribute to the decomposition of natural animal remains in the wild.
