We got bedbugs from a hotel we stayed at in Kincardine, Ontario. Because it was a relatively recent infestation, GreenTech recommended that we try the chemical treatment instead of the heat treatment. They said it would most likely eradicate the problem and was much cheaper than the heat treatment. We had two visits from Dan, the owner of the company. Unfortunately, the problem still persisted in one bedroom. Dan promised us that he would get rid of the problem, no matter what it took and at no further cost for more chemical treatments, but we were fed up at this point. We asked to have the heat treatment done, and Dan arranged that for us at much less than the regular cost, plus he credited us for the amount we had paid for the failed chemical treatments. Really great company!
