Plaster Bagworm (or Case-bearing Clothes Moth larva)

Typically found inside residential homes, garages, and sheds, often on walls, ceilings, and in corners under furniture.

Larvae feed on natural fibers such as wool, silk, hair, fur, and spider webs; they can also scavenge on dead insects.

The larva builds a flattened, spindle-shaped case from silk and debris. It can emerge from either end of the case to feed or crawl. They undergo a complete metamorphosis inside this protective silken home.

They are considered a minor domestic pest because they can damage clothing and fabrics made of natural fibers. They do not bite or sting humans and pose no direct health risk.
