Natural Habitat

Commonly indoors, found on walls, floors, and under furniture where dust and pet hair accumulate.

Diet & Feeding

Larvae scavenge for organic fibers, including human or pet hair, wool, spider webs, and dead insects.

Behavior Patterns

Larvae construct a flattened, silk-lined case covered in debris for protection. They can pull their heads in from either end to change direction. The larva undergoes metamorphosis inside this case.

Risks & Benefits

Generally considered a nuisance pest. They can cause minor damage to woolens or silks, but pose no direct health risk to humans or pets.
