Plaster Bagworm

Humid indoor environments, often found on walls, under furniture, or in closets

Larvae feed on spider webs, wool, human hair, and silk fibers

The larva constructs a silken case covered in sand or dust and drags it along while feeding; it can move from both ends of the spindle-shaped case

A nuisance pest in homes that can damage fabrics made of natural fibers; poses no direct health risk to humans
