Case-bearing Clothes Moth (larva/case)

Found indoors in closets, carpets, and storage areas; naturally occurs in bird nests or animal dens.

Feeds on keratin-rich materials such as wool, fur, silk, feathers, felt, and human hair or lint.

The larva builds and drags a portable, flattened case around with it for protection. It never leaves this case until adulthood. They prefer dark, undisturbed areas.

Pest species. The larvae cause damage by chewing holes in natural fiber textiles like wool sweaters, rugs, and upholstery. No direct health risk to humans (doesn't bite or sting).
