After battling bedbugs for four months, after I brought them home from my hotel, I called this Company. Wow! My bug problem was solved within 24 hours!
Prior to, I tried home remedies one on the web and spent about $200 in products spent 500 and getting the house sprayed and bombed and poisoned, and they were still here. People! Use this company they are more affordable than any other company out there and Scott does overkill on your house he’s very detailed you will get a follow up call and he will check your preparation of the house prior to your service. My only issue is that I wish I would have done this at the very beginning it would have saved many sleepless nights and a lot of cash. This treatment was worth every penny and it is a lifesaver don’t dally call them!

Not many people know about or are educated on bed bugs. me and my son had been bit and had no idea until when began to have rashes. When I called Gateway Thermal Solutions I was at my wits end. I stayed in an apartment complex with 5 other tenants and not knowing where the bugs were coming from left me and my son up many of nights. After a late call to Gateway Thermal Solution they came out the next day to check it out and spent about 30 to 45 minutes educating us on these little critters. I felt not only comfortable with their service but the process as well. They took their time and I did not feel rushed at all and they made themselves available to answer any and all of my questions without limit. I recommend their services to anyone who think they have bed bugs or if you just need a course on these tiny nuisances. Thank you to David and Scott.

Owner/Operator showed up same day to give a quote. He was polite, professional and honest. Which, was huge since he was the third quote of the day and the only one that was up front about the odds of the heat treatment working. Managed to move scheduling around to help us out with our bed bug problem.

Day of heat treatment, he showed up early and was on-site the entire time, even watched our house while we had to step out to take care of prior engagements. 10/10 would recommend to anyone that finds themselves plagued by the little blood sucking pests. Bed bugs were gone and all that was left was to clean up the husks.

We were so impressed by Scott McDonald's integrity and work ethic. He carefully looked at every room of our 4300 square foot house and told us in his professional opinion the bed bugs had been contained to one room. He was honest and didn't suggest a costly treatment. We would use him again and recommend him . Thank you

Great service! Fully explained everything that the treatment was going to do and answered all of my questions. I was even able to go inside during the treatment and see exactly what was happening. No more problems post treatment. Really nice guy.
