Household Casebearer

Commonly found inside homes, on walls, and in corners where dust and silk accumulate.

The larvae feed on spider webs, wool, hair, silk, and organic debris.

The larvae live inside a flattened, spindle-shaped case made of silk and debris, poking their heads out of either end to move or feed.

Harmless to humans but can be a minor pest of natural fabrics like silk or wool. They help clean up organic debris but are generally considered unwanted indoors.
