If possible get your treatment from a local outlet like Home Depot, a hardware store or an agricultural/farm supply store. If you can afford it get one of those steam mops like Shark has. It comes with a unit designed for hand steam treatments of the bed and the hot steam will kill the bugs. You will also need it if you have to treat carpeting. Professionals use a combination of treatments and you will too in order to be successful. Good luck!
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
