Household Casebearer

Found inside residential homes, specifically in bathrooms, bedrooms, and on walls in humid climates.

The larvae feed on wool, silk, hair, and biological debris such as spider webs.

The larva constructs a protective, spindle-shaped silken case covered in dust and sand. It can turn around inside the case to feed from either end. The adult is a small, inconspicuous moth.

They are considered minor household pests because they can damage natural fibers and clothing. They pose no health risk to humans.
