Household casebearer

Found indoors on walls, ceilings, and in dark, undisturbed areas like closets.

Feeds on spider webs, dust, hair, feathers, and occasionally wool or cotton fabrics.

Larvae construct a portable, flattened silken case incorporating debris and drag it everywhere. Adult females are wingless and remain in the case, while males are tiny, weak-flying moths.

They cause minor cosmetic damage to walls and can chew holes in natural fiber fabrics. However, they are not venomous, do not bite, and pose no direct health risks to humans.
