Household Casebearer moth larva

Commonly found inside homes in humid climates, often on walls or in corners

The larva feeds on spider webs and natural fibers like wool and hair

The larva builds a protective silk case covered in sand, dust, and debris. It can pull its head and legs into either end of the case to hide or move.

They are considered minor household pests because they can damage silk or wool fabrics, but they do not pose any health risks to humans.
