Household Casebearer

Indoor environments, particularly in humid tropical or subtropical climates, found on walls or under furniture.

The larvae feed on spider webs and natural fibers such as wool, fur, hair, and even lint or dead insects.

The larva constructs a protective silk case covered in sand, soil, and dust. It can poke its head out from either end of the spindle-shaped case to move and feed. They eventually pupate inside this case.

They are considered minor household pests because they can damage clothing or upholstery made of natural fibers, but they are harmless to humans and do not bite or sting.
