Northwood, NH
The tech came here while I was working from home. Just asked that I close the first floor windows while he did the treatment. He did his work and left without causing me interruption. Your techs always do a great job.
Northwood, NH
The technicians and the products are excellent. Your billing process, however, is lacking. I was told that someone would contact me before the new contract started. I asked if there was going to be a charge for this service yesterday since I hadn't heard from anyone and was told no. So, I was a little surprised when I got a bill for $225 with no indication of what this covered, only that it was semi annual, but not what part of the year it covered.
Barrington, NH
He was professional. Arrived on time and did a thorough job of spraying.
Dover, NH
We've been happy with the service. The only negative is that we will get a postcard announcing that they will come by 'soon', and they don't come for weeks or months. We have to call to schedule, usually after we see activity inside the house.
Amherst, NH
Outstanding. Colonial worked around our rainy weather. Very thorough in application of pesticides. Craig, was very helpful with his information and knowledge sharing. We are pleased with the early results. We will be vigilant in watching for seasonal activity and utilize Colonial's services to deal with any re-emergence issues. Your technician, service and assistance were all excellent. Please note the technician that serviced our home was Craig, based out of Nashua, NH. Job well done! Thank you.
Middleton, NH
Thourough and explained what he was doing. One time for our appointment. As always great service!

Very expensive for a quick spray. Terminex is much more reasonable. We like to support local business people but this wasn't worth it.

Bedford, NH
This is the first time we've used Colonial Pest Control. Bill, our technician, was extraordinarily helpful and proficient. He explained the entire process of dealing with carpenter ants and put our minds at rest regarding the safety of the chemicals and the chosen application process. Bill was able to quickly identify the carpenter ant nest which was located in the surrounding area of our home. Bill took the time to treat all necessary areas carefully. It's only been a couple of days since the appointment but we are 100% convinced that we made the right decision choosing Colonial Pest Control.
Highly recommended company. Bill was phenomenal.

Manchester, NH
As always the appointment went very well. My concerns were listen too and actions taken with to try and eliminate those pesky bugs. Very satisfied with my appt
Thank you.
Rye, NH
we called you out to handle the mice control and hornets and wasp, the technician was not confident if he was able to secure against mice and did not cover all of the hornets and wasp, he said the nests were too high up, if the nest were low I would of handled them on my own. I am not confident that I got value for the $500+ that I spend on the services.
Windham, NH
The technician was very knowledgeable and helpful.

Pelham, NH
My first appt was rescheduled due to heavy rain but I was rescheduled within a week. Lance was great. He explained everything, answered all my questions and was friendly and professional.
Goffstown, NH
Kera was very nice and was just finishing up when we got there. However, we're disappointed your team got to us so late into the spring as we've already started having ant issues which we've never had before. We'll be expecting you earlier in the spring if you want to keep our business going forward.
