Use a vacuum and a steamer to kill bed bugs. Get deep into the tufts, seams, cracks including parts of the bed frame where the bugs can hide. Heat your entire home to 135 degrees for several hours to be more certain. These are hard to get rid of. You can use several space heaters on SEPARATE circuits. That's separate circuits not outlets. There is a difference, otherwise you will pop the breakers, blow fuses or start a fire.
