New Ipswich, NH
I’ve been a customer since 2001-ish. I have lived in 3 different houses since that time and Colonial has services every house. They have taken care of much, ants, bees, bats and flying squirrels. I have recommended them to family members and friends who have chosen to use them and also been happy. Thank you Colonial.
Hooksett, NH
We have been very happy as first time customers. The technician who came to our house was more than accommodating and even offered to take my dog out before application since I was on crutches with a broken leg! Great customer service and hardly noticed he was there at all (which is a good thing).

I was very please with your tech person. In addition to knowing exactly what to do, he explained what he was doing and why. He was friendly and courteous while also being very professional.
Nashua, NH
The technician for my first appointment showed up ten minutes early and was extremely polite and thorough. Since my house was treated, the spiders have nearly vanished, and I've only had one or two hornets that have managed to sneak in. I look forward to my next appointment in the fall!
Manchester, NH
Had my first mouse problem this past winter since living in this house for the past five years. One phone call and a day later they were out to bait and set traps at no charge because I am a seasonal customer. Other providers wanted upto $350.00 to do the same job. Six weeks later they were back out to re-bait the traps and removed the old nests. Completely satisfied!
Hollis, NH
We have never had any problems and we recommend your company to everyone we know.
Goffstown, NH
Colonial has been extremely sensitive to our needs. For years we attempted to battle Carpenter Ants in and around our home to no avail. Now I leave that to Colonial as they have done a tremendous job. My wife is also extremely allergic to bee stings. Colonial has promptly taken care of any nests that we have identified around the home. They always lets us know in advance when they are coming to the area and leave detailed notes of their treatments. I am very satisfied with this company and would recommend them to anyone.

Hudson, NH
The service tech was very professional! And , a diligent worker. Yet , I'm still seeing black ants ,spiders , flies , bees and other small insects on my desk. I'm surprised they are still energetic and don't seem affected by the treatment.

Very happy with work. Installer was very knowledgeable and pleasant.
Nashua, NH
We are new to Colonial Pest Control. Colonial listened to us and came up with a solution we are very happy with. Thank you to Joe, who talked with us on the phone, and to Russ who came out to the house, listened to our concerns, visually assessed the situation, clearly described what he was going to do and then applied the treatment. Our experience could not have been better.

Derry, NH
I have been using your service for over 10 years and I must say that there has never been an insect problem inside or out. I cannot remember the last time I saw an ant anywhere near the foundation. Doing around the pool house is an added bonus. Twice a year is the way to go.

Tech was very good. She is a keeper.

They came about a month ago for an ant infestation. Haven't seen an ant since. I've also had them take care of yellow jacket nests in the past. A+ service.

Amherst, NH
Ultimately, we thank you for a consistently bug-free home but also for your friendly and courteous service. We've been using your services for many years and enjoy the comfort of knowing there are no (other) rent-free residents. Do you have a potion to abate the kids? JK!
Raymond, NH
as of right now we are still getting a lot of ants but you said to give it a month. It has only been 2 weeks.
Nashua, NH
The semi-annual service has made all the difference for us, preventing what was an annual ant attack in our house. It also has eliminated wasps we had outside near our deck in the roof soffit vents. When we had a mouse problem, Colonial came and treated it quickly and effectively as a service call included in the semi-annual plan. Excellent service and technicians over the past 12 years!
