Natural Habitat

Indoor environments, particularly in closets, drawers, and carpets where natural fibers are present.

Diet & Feeding

The larva constructs a protective silken case or 'sleeve' covered in fiber fragments and drags it along while feeding. They are photophobic and prefer dark, undisturbed locations.

Risks & Benefits
