Windham, NH
We are new clients of the Colonial Pest Control. We recently received our first treatment and thus far, we have not seen any little rascals around the foundation or inside the house, and that's good news. We are happy to say if the service and the results continue to be this good, we will continue using Colonial Pest Control in the future. Thank you for a job well done!
Hampton, NH
I’ve been a loyal Colonial Pest Control customer for 22 years and two houses. They are serious about taking care of our home and whatever pests we experience. I like their new policy of calling/texting before treatment to ensure we have a chance to voice any concerns and they are responsive and professional.

The treatment is working, but the carpenter ants are more lively. I must have a large infestation and feel I need you to come back when-ever you think is the best time sooner
or later? Please leave a message on E-mail or call 603 474 2111. Thankyou!

Manchester, NH
Technician came unprepared not knowing what he needed to do inspection was not thorough I am still seeing carpenter ants all over the yard porch deck and fence there was no inspection done for anything other than the ants that were mentioned on the phone despite the conversation when I started and initiated the appointment that there would be a thorough inspection for All types I’ve home pest. I am looking for an immediate before of the service.
Pembroke, NH
Great customer setvice.
Hampton, NH
Every year we seem to be more & more delayed with the semi-annual service. What used to happen in early spring now happens in summer - a bit frustrating when you receive a postcard alerting you to the service and it takes 4-6 weeks to happen. The individual who came this year announced his arrival and indicated he would call before he left the premises which he did not so we were unable to discuss the ant problem we had called earlier about. Time will tell what happens in the fall with the next spray.
Nottingham, NH
We are still having the ant problem.
Somersworth, NH
So far so good. Thank you for prompt service. Queen carpenter bees appear to be taken care of and dropped within days as your technician claimed they would. I see occasional bees flying around the back deck (attached to the house) so not sure if they are the male bees looking for the females. I will keep my eye out for them. Thank you again.
Newmarket, NH
It’s been a complete year since I changed from Terminex to Colonial and and am very happy not to have any bugs in my home. Not even ants....
Mont Vernon, NH
Excellent and very professional service. Fair prices too.
Hampton, NH
We had our inspection yesterday and wanted to let you know how impressed we are with the service. We LOVED Mark McKenna, boy does he know his stuff! He was so understanding of our questions and made us feel very comfortable. His knowledge of different kinds of pests impressed us. In no time, he found the spot where the mice were coming in and made suggestions on fixing a couple of things to help stop them from entering the house, which I will do.

I have to tell you the service from the beginning with you and then the actual "hands on" getting us pest free has been nothing less than spectacular, We are looking forward to being your customer.
Hooksett, NH
Hi - We have had Colonial Pest Control for several years and are quite happy. It is nice to have the continuity of the same specialist. Russ, we love you!

It took a couple of weeks for our ants to be completely gone. Over all we were very happy with the results.

Manchester, NH
Hi, I have been a customer for many years, 2 houses. I called on Friday, June 12, 2020 because I saw a mouse in my house in Manchester, NH. I am very unhappy that you can not address this for 2 weeks; June 25.
So, no I am not happy.
Manchester, NH
We had a nasty hornet population prior to colonial pest treating. They were flying by the dozen and daily. Now we have not seen all but maybe the occasional bumble bee here and there. We also had a terrible ant colony on our patio area that they treated and its like new again! No pesky ants! Thanks colonial!
Manchester, NH
Very professional; on time and explained what they were doing and all about the type of bees we had.
Weare, NH
Great job. Insects and hornets dramatically reduced.
Hooksett, NH
Very thorough in making sure everything is covered.
Exeter, NH
Assessed and treated carpenter bees and ants in one call. Awesome! I hate when a company charges you just to come out and tell you what you already know. Really appreciate the time/money saved.
Hollis, NH
Colonial has been doing annual spring and fall treatments on our house since 1990, and we've always been happy with them.

Occasionally ants get into the house anyway and Colonial has always been very prompt at responding, but strangely this year when it happened the earliest the appointment could be scheduled was more than two weeks in the future. We were afraid carpenter ants might gain an inside foothold in that time, so I had to do a perimeter walk of the house to see if I could find where they were getting in. Couldn't find it, will try another perimeter walk soon.
Tuftonboro, NH
Very fine company and excellent service. No complaints.
Hooksett, NH
The tech you sent is the best.i had an other crew working on the day he came
He held a meeting with them to make sure that they would be safe.
Exeter, NH
Colonial Pest Control has good service overall. They call, then email a photo of your technician before treatment, and the tech texts on arrival. Service is effective. My only complaint this year is that after their initial contact in April, they had to re-schedule twice because of rain (no problem there), but they didn't set another appointment after the second cancellation. If I hadn't called a month later, would they have come?
Hollis, NH
Fabulous experience! They were very quick to schedule, easy to communicate with, very attentive to our safety and our pets' safety, and the treatment worked! Would recommend and use them again without hesitation.
Salem, NH
Excellent service! Would recommend Colonial Pest to Everyone.
Portsmouth, NH
