Very professional and easy to work with. Came out and gave me a free quote to do the work. Not only did they get rid of the carpenter bees but they were able to remedy the problem so they won’t come back.

My husband and I, both, have run over underground yellow jacket nests while mowing the lawn. And both have suffered the consequences! Each time though, Colonial Pest Control comes to the rescue. They arrive in a timely manner and completely remove the nest. Couldn't be happier! Thanks. The Merciers.

Epping, NH
After using Colonial Pest Control one time for mice (which they did a wonderful job; never saw one again), we decided to sign up for the quarterly program. We just had our first visit and the technician was wonderful, friendly, knowledgeable, and explained everything he would be doing for ants, wasps, hornets, etc. Since he has left days ago, we have not seen a single ant or wasp, etc. I would (will) recommend them to all my friends and family!

Weare, NH
Not pleased at all - just received bill for first annual treatment $195, copied the following right off the invoice;
Time In: 6/27/19 9:07 AM Time Out: 6/27/19 9:18 AM
You have got to be kidding me, exterior treatment and supposedly inspection in 11 minutes, oh and by the way the issue with the small 'sugar' ants was not cured by the pellets that you supposedly applied around the exterior foundation. A week and a half later they are just as active as they were when we pointed this out to your employee that was at my residence. Look forward to hearing from you!
Exeter, NH
We are happy with Colonial Pest Control service treatment for carpenter ants. Our service technician (Justin) was very knowledgeable and professional. He clearly communicated what the treatment plan was and was able to find and treat the exterior nest. Since the treatment, we have not seen signs of ant activity in the usual areas. Would definitely recommend and will use them again in the future.
Barrington, NH
I can’t leave a review until you finish the work!! The outside never got sprayed because it was raining and no attempt has been made to schedule it.
Hampstead, NH
I've been a customer in both Hudson and Hampstead. Both locations were pest-free once Colonial took control. Always courteous and professional. 5* all the way.
Nashua, NH

Bow, NH
I used Colonial for about 10 years from 2003-2013 but took a break from all pest control while I raised bees. I was completely satisfied with their service and had no insect issues over the years they treated our home. I began using them again this spring. The technician, Russ, was very informative and helpful, but it is too soon to comment on the results. I like that I received a summary of the chemicals used with my receipt.
Nashua, NH
I'm always pleased with your service. Please apologize to the person who came to our house on Thursday. When he said he would move his truck so I could get out of the garage I didn't realize he was waiting in the truck for me to leave! Sorry if I kept him waiting.
Durham, NH
The gentleman who serviced us was cordial, on time, and explained the process of eliminating our pest problem.
He also discussed our options for future service (which we signed up for). I would recommend Colonial Pest Service without hesitation.
Chester, NH
Very pleased with your service. Techs are always great.
Pembroke, NH
The technician explained the inspection process in detail which was appreciated. He also tended to trouble spots and areas of high insect activity in a thorough manner. We are very pleased with the service we received and will not hesitate to recommend Colonial.
