Tinea pellionella (Case-bearing Clothes Moth larva)

Found indoors in residential homes, warehouses, and locations with stored natural fibers like wool, silk, or fur.

Larvae feed on keratin-containing materials such as wool, feathers, fur, hair, and sometimes synthetic fibers blended with natural ones.

Larvae construct and live inside a portable silken case incorporating debris and fibers. They move by extending their heads and legs to drag the case along. They prefer dark, undisturbed areas.

They are serious household pests that cause damage to clothing, upholstery, and carpets. They offer no direct benefits to humans but serve as decomposers in natural ecosystems by breaking down animal remains.
