Case-bearing Clothes Moth (larva)

Indoors in dark, undisturbed areas such as closets, under furniture, or behind baseboards where natural fibers are stored.

Larvae feed on keratins found in natural fibers including wool, silk, fur, feathers, and hair. They do not eat synthetic fabrics.

The larva constructs a protective silken case around its body, often incorporating bits of the fiber it is eating. It carries this case as it moves. They are photophobic (avoid light) and complete their entire life cycle indoors.

They are a household pest that causes significant damage to clothing, carpets, and upholstery made of natural materials. They pose no direct health risk to humans or pets but are economically destructive.
