Plaster Bagworm (or Case-bearing Moth)

Commonly found inside residential homes, attached to walls, under furniture, or on rug fibers in humid climates.

The larvae feed on spider webs, wool, human hair, silk, and shed skin cells.

The larva constructs a protective silk case covered in sand, dust, and debris. It is open at both ends, allowing the larva to turn around and feed from either side.

A household pest that can damage woolen clothing or rugs; they are harmless to humans but may indicate local moisture or humidity issues.
