Webbing Clothes Moth Larva (specifically the casing)

Dark, quiet areas within homes such as closets, drawers, storage chests, and under carpets where natural fibers (wool, silk, fur) are stored.

They feed on keratin-rich natural fibers, including wool, fur, silk, leather, feathers, and occasionally cotton or linen if soiled with food stains or sweat.

The larvae spin silken tubes or cases (like the one pictured) for protection, blending in with the fabric they are eating. They avoid light and are rarely seen unless disturbed.

They are a significant household pest that causes irreversible damage to expensive clothing, rugs, and upholstery. They pose no direct health threat to humans (they do not bite or sting) but can destroy valuable property.
