“Used before and found to be very good. I got a bed bug kit with a smoke bomb, pesticide spray and a powder too which seem to work very well. Just prep the room well, open drawers, turn tables, chairs up side down, break down the bed and so on and then set the smoke bomb off (I put on a baking tray and left overnight) Close windows, vents, bedroom door. Follow up with spray and then powder on cracks and electrical sockets. Got rid off the bed bugs. I did throw out old mattress and get a new one alongside new wooden slats but I kept my original bed frame. This is an effective piece of kit and much cheaper than using a pest control company!”
