Chris was absolutely wonderful. In lieu of trying to sell a full contract package he suggested a more accommodating route that suited my needs. He delivered the package, provided instructions and even fixed my door (LOL). He provided a service that fit my needs and my ants are gone! I would recommend ATC to everyone. He didn't push a service I didn't need. Thank you Chris for your honesty & service!

ATC Pest Control honestly and truly gives Outstandingly Great service! We've had a mouse problem, and although it's only been a few days since their visit, we've already seen a large decrease of any indication of the mice! It definitely looks like they're on their way out completely! Chris educated me very much on the phone, and Tyler actually continued with really great info with how to achieve the best results. In fact last year we had a rat problem in our small warehouse, and their convenient little bait stations worked perfectly to eliminate these larger rodents. A very trusted company AND very trustworthy people!

We had a bat problem inside our house and ATC offered a comprehensive plan to combat the problem. The house was inspected for entry points and the gaps and crevices were filled. They were able to pinpoint the attic space where the bats were hanging out. We havent had a bat in the house in weeks. We are very pleased with the service and recommend them highly

ATC performed services for our condo a few years ago and did a wonderful job. They were very patient since there were 5 units/owners that needed to be coordinated with. The staff and service people are extremely knowledgeable, courteous and thorough. I recently had them come back out to do an inspection. Again they were very courteous. Luckily, no trace of termites this time. I highly recommend them.
