My construction laborer recommended me to use WD-40. I guess they were using it long time ago to get rid of bed bugs in their labor camp rooms. It's been three days since I sparyed a can in my place. I never had any skin bites since then. Use it underneath your bed, in the corners and at the ceiling where my neighbor's bedbugs went through. You can get it at the grocery stores or hardware shops. The smell of WD-40 is gone now but I think its the grease of the liquid that bedbugs hate. Goodluck and pleasant dreams.
