Household Casebearer

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

Feeds on spider webs, dust, hair, shed skin, and animal-based fibers like wool.

Larvae construct a portable, flat, flask-shaped silk case encrusted with debris, dragging it along surfaces.

Causes minor aesthetic damage to textiles and woolens, but poses no direct health risk to humans.
