Household Casebearer (Plaster Bagworm larva)

Indoor environments, found on walls, floors, and in closets, especially in humid or tropical climates.

Larvae feed on spider webs, woollen fabrics, silk, and human hair shed in the home.

The larva constructs a protective spindle-shaped case from silk, sand, and dust. It can poke its head out from either end to move or feed.

Cosmetic household pest; can occasionally damage silk or wool items. While they don't bite humans, their presence often indicates high indoor humidity or excessive dust/spider webs.
