Justin was wonderful and told me everything he was doing. I moved stuff in the garage for him and went back inside. After he left I went back to garage and everything was put away. It put a smile on my face. Thanks.
Brentwood, NH
I was happy with Mark the technician that came to my house. He was thorough and explained things he was doing to eradicate mice in the attic and wherever. However, after his visit that night I heard unbelievable banging on the ceiling of my bedroom which was quite disconcerting. Although I am aware that we need some time to accomplish that, I just had one question for him the following day and requested he call me briefly. He did not.
As a new customer and one who will try not to be a bother, I would have thought that a call would have been nice. Not happy with the fact that I got no call or even a return text. And I signed up for a full year of service for $460. Hope I made the right choice for an exterminator.

Exeter, NH
The job was well done with all internal and external places checked out for signs of unwanted critters. None were found and no signs of rodents. Have time to listen and verify that all is tight with no entrances. The tech explained the protocol. He closed doors and turned off lights as he left each area. Nicely done. Thanks.
Pelham, NH
Russ was very knowledgeable about our problem and it appears he has solved it. He was easy to talk to and showed me what he was doing to solve the situation. I felt he did what he was suppose to do and will call them again in the future should they be needed.
Thank you for solving my problem.
Manchester, NH
My technician was very thorough. He listened to my story and asked questions to help him diagnose my issue. He examined my garage, basement, outside perimeter, and attic, even though I only mentioned an attic problem. He explained his thought process and solicited my opinion before we jointly landed on a solution. Once he completed his treatment he explained what I should expect going forward and the timeline to expect results. This was everything I could have expected.

Good. Very pleased with process.
Henniker, NH
My rating would have been five stars if you would tell your computer to actually get my name right.
But I was completely happy with your Quality manager’s visit and very complete explanations about how the trapping process works. He was informative, knowledgeable, and helpful. He encouraged my questions about what I can expect from that, as well as issues with the construction of my home that create a challenge to the goal of eliminating the rodent population. I appreciated his kind honesty, and I feel a lot better now about what your company can do for me.

Sandown, NH
From start to finish this was a great experience. The customer service was perfect as Joe listened to my situation and explained clearly what needed to be done. On the day of service, there was clear communication during all phases of the work. The exterminator was professional, knowledgeable, and walked through the house with me to understand the problem. I never felt rushed.

Lance is great! Thorough, takes time to explain the process and value of the service. Then gets down to business! Addressed a rodent issue in our detached garage and reviewed the entire property for potential pest entry points.
Nashua, NH
Scott was very thorough & confident that he took care of any openings where mice were getting in. We hope he has as well. 😀.
Deerfield, NH
Very impressed so far. Russ was very professional and explained exactly what he was going to do to eliminate the carpenter ants and ever since his treatment we have not seen any ants in the house. I like that he uses a needle probe to get into the areas of most concern without drilling holes or just fogging the whole house. I am so impressed that I plan on signing up for the annual prevention treatments.
Manchester, NH
Dana was my technician. Super helpful explaining the process. He even helped with explaining a different problem I was having even though his company didn’t provide those services. Would totally recommend this company.
