Plaster Bagworm

Typically found inside residential homes, garages, and sheds, specifically on walls and ceilings in humid climates.

In the larval stage, they feed on natural fibers, spider webs, wool, and human hair shed in the home.

The larva constructs a silk case covered in sand, dust, and debris. It is open at both ends, allowing the larva to feed from either side without turning its body around inside the case.

They are considered minor household pests as they can cause slight damage to woolen rugs or clothing, but they are generally harmless to humans and are not known to transmit diseases.
