Smow, I really think you need to leave it to the your Pest Controller to eradicate the blighters, mixing chemicals by applying different products could end up with a lethal cocktail, also be aware that you are then sleeping amongst it. Many chemical are not designed to come into contact with your skin.
If you arent getting anywhere with solving this problem, call in a different Pest Controller. Bed bugs can be difficult for pest controllers, I doubt very much that "off the shelf" products will be effective. Controlling bed bugs is very often down to the correct application of these products. Unless you are an experienced pest controller, I doubt any of these other products will work, just puffing or squirting it around will just waste money and could well be a health hazard for years to come.
