Things You'll Need
Instructions
Look for bagworm cases on the bottoms of chairs and bookshelves, and along baseboards and bottom edges of walls. Remove bagworm cases.
Clean and vacuum the house thoroughly. Take extra care to remove all spider webs because bagworms feed on them.
Place mothballs in airtight spaces to ward off bagworms. Mothballs are pesticides and must be used carefully. Follow the directions and only place them in spots listed on the label.
Treat indoor cracks and crevices with boric acid dust or other insecticides designed for clothes moths or bagworms if the house is infested.
Contact a pest control company to fumigate the house for severe infestations. Home products for fumigation are not currently available for plaster bagworms.
