Household casebearer

Indoors in damp, humid environments, often found on walls, under furniture, or on fabrics in closets.

Larvae feed on natural fibers (wool, silk), spider webs, and organic debris like dead insects or hair.

The larva lives inside a silken case covered in sand or dust; it can turn inside the case to protrude from either end.

They are nuisance pests that can damage clothing and household fabrics; they pose no direct health risk to humans.
