ought spray, keeping the apartment very clean and clear of clutter and spraying every night all around the bed, the couch, the closets, etc. I finally talked to a friend who had them a few years ago and she said it was absolutely necessary to get professional help. I am now in the process of preparing my apartment for them-- I laundered every piece of clothing, linens, etc. that I own, and wrapped everything else that might be a bed bug haven in plastic. After the exterminators do their thing tomorrow, I'll go around the entire apartment and caulk everything-- where the floor meets the wall, where the radiator pipes are, etc. It's been a really costly and upsetting process.
