text: try setting off bug bombs, be sure to open all closet and cabinet doors, dresser drawers, medicine chests etc... this will result in having to do alot of laundry and dishes, but living roach free will be worth it. Also, keeping dishes done, and food crumbs and spills cleaned up will help keep them from returning. You could also set out boaric acid, it kills roaches too.  If after all this you still have roaches, you may have to call a professional. Good Luck, I hate roaches.
