Plaster Bagworm

Typically found inside residential buildings, attached to walls, under furniture, and in corners where dust and silk accumulate.

Larvae feed on spider webs, wool, human hair, fur, and natural fibers like silk.

The larva constructs a protective, flattened silk case covered in debris and sand. It can emerge from either end of the case to feed or move. As it grows, it enlarges the case.

They are nuisance pests that can damage clothing or carpets made of natural fibers. They do not bite or pose direct health risks to humans or pets.
