Household Casebearer

Found inside buildings, particularly in humid or damp areas like bathrooms and closets

Larvae feed on spider webs, wool, hair, and various biological remains

The larva builds a flattened, spindle-shaped protective case out of silk and dust/debris; it can emerge from either end to move or feed

Generally considered a minor household pest; they do not bite humans but can cause damage to natural fiber textiles or fabrics
