After exhaustive research into companies that provide heating systems for the eradication of bedbugs, I opted to deal with PestPro Thermal. Wonderful people to work with and the system practically runs itself. Like anything else, you'll tweak the procedure to where it works best for you. The on-the-job training by PR Olsen in South Dakota was well worth braving the cold. All in all, the only complaint I have about the system is that I didn't make the move sooner. Thanks Bob, Michael, and Hugh!
