We spent over a year trying eradicate our bed bugs using traditional chemical methods because, frankly, it is much cheaper. I found out why: $1200 dollars and 3 treatments later, we still had bed bugs, my wife and I were at our wits ends, and I was starting to develop serious concerns about the amount of chemicals we had put in our house. Take it from me, who has been down that road multiple times: chemical treatments just do not work. They reduce the problem but they do not eliminate the problem.
(Also, I can tell you horror stories about how, with chemical treatments, you have to be used as live bait to draw the bed bugs into your chemically treated bed so, for weeks following the chemical treatment, you are still getting bit. Good luck getting any sleep.)
We finally turned to heat treatment and called K9 Bed Bug Detectives. Granted, it is more expensive but, after only one treatment, the bed bugs are completely gone. No being used as live bait. No waiting 3 weeks to see if there has been improvement (like chemical treatments). With K9 Bed Bug Detectives, one treatment and the bed bugs are just gone.
I know how your are feeling right now. I've been there. Do yourself a favor and call K9 Bed Bug Detectives.
