FYI there are only a few companies that actually do fumigation. Notice that you do not see a bunch of different companies’ trucks driving around with bottles of fumigation gas on them. You hire a pest control company and the company that actually does the fumigation is a subcontractor. Thus many of the companies that you actually deal with are simply fronts, middlemen, for the guys who actually do the work. My guess is only a few companies have passed the regulatory and liability hurdles to do gas fumigation. Thus it matters very little (really only price) who you hire for the fumigation.
Spot treatment and control of subterranean termites is a whole other ball.
