Household Casebearer moth larva

Found inside homes, particularly in high humidity areas like bathrooms and kitchens, or on walls and under furniture.

Scavenges on organic debris including spider webs, hair, wool, and silk fibers.

The larva constructs a spindle-shaped silk case covered in dust and sand. It can turn around inside the case to protrude from either end.

Generally harmless to humans but considered a nuisance pest; can occasionally damage natural fiber textiles or wool rugs if present in large numbers.
