Somehow, I think paying extra to be a guinea pig might not be the best idea. At least not when we have so many other cheaper and more efficient methods and chemicals to consider, at least at the present. Mainly, soil poisoning. Yes, it takes experience and expertise - so make sure you get someone that's been doing this, on YOUR type of house, for a long time. Best chemical, today, is Termidor.
Premise is almost as good.
Opt out of termite baiting or the application of any chemicals directly to the wood. Some exterminators also push wood treatments of one type or another. I think, in most every case, these are worthless add-ons. You will, of course, be able to find hundreds of exterminators that disagree with me, but I am of the opinion that an exterminator should recommend the cheapest, most effective method for termite control. That method is soil poisoning.
