Encasement
The key to killing and preventing beg bugs from infesting is to isolate them with encasement. Once you have heated or vacuumed all clothing or bedding, try to cover them up with suitable items. Many zipper sheets are specially designed for this purpose. They can cover hiding areas to keep bed bugs from penetrating or coming outside. Ideally, you should leave these items encased for at least 6 to 12 months to prevent infestation. [8]
