I reached out to ATC with a bee problem and they took care of so much more than just this. Staff members (Chris and Ian) had obvious expertise in pest control and responded immediately with care, patience, competent, and professional service. The price was more than fair and the service was comprehensive. They even showed up early!
I'd recommend ATC to anyone in need of efficient and effective pest control services from a company that cares and does an excellent job!

I have two properties that ATC inspects on an annual basis. The inspectors are always on time and are very polite and knowledgeable. They do a very detailed inspection for signs of termites plus ants, centipedes, spiders, etc and have successfully treated areas as needed. I would highly recommend this company for any bug problems.

ATC has taken great care of the pest control needs for our property for several years now! I do think their prices could come down a bit (we received essentially the same services from another company for half the price when we lived in Pittsburgh, which is a similar COL area), but I have no complaints regarding effectiveness of their techniques or customer service. Every employee we've been in contact with has been professional and kind. Their response time to our needs has consistently been reasonable. We are pleased to be ATC customers and will continue to support their business!

I have always had great service with ATC. My technician is usually Ian and he is always very thorough and informs me of what he sees and how he is treating a problem! He has also been flexible with timing when Im on his service since Im usually coming from another location to get to the home he is treating. Also love that this company will come back and retreat if problem/issue reoccurs without an extra charge. Weve been with ATC for 3+ years now.

Was able to get an emergency appointment to eliminate a wasp nest that was forming under the siding above our front door. Technician was on site less than 24 hours later and was able to remove the nest. Emergency appointment was expensive, but worth it since it might have been even more expensive to have to replace drywall if the wasps went unchecked for another week or two.
Moreover I must express my appreciation for how quickly they were able to make this happen; they had to have move mountains to make it possible, and at no point were we made to feel as though we were inconveniencing them even though we knew we were. Everyone involved was completely professional and friendly. As a result, we will definitely be making use of ATC's services in the future should the need arise.
