We have only had our first service but so far we are very pleased. I was able to get an appointment in a very reasonable timeframe and we saw an improvement in the big situations we were experiencing almost immediately. The tech who worked at our house was efficient and answered all my questions and gave me a few tips and tricks as well.
Lee, NH
I was very happy with Anthony S. who came to do the semiannual service this year. He came to the door to introduce himself and let me know he was here. He answered a question that I had and then went to work. I also have had good customer support from my sales/customer service rep Joe Oleski, for a big project last year and my service contract this year. Thank you.

Our service person comes, checks in with us, does his job, and leaves for our son's house where he repeats the process. No complaints here.
Mr. Hewitt.
Dover, NH
We are very pleased with the pest control maintenance provided by Colonial Pest Control.
Starting from the assistance from the office staff and right thru including the service technician.
We needed authorization from our condo association to have our own pest control service and we requested assistance from the office staff to provide information in order to obtain the approval. Joe was extremely patient and helpful in obtaining the needed specifications. Also the service technician answered all my questions, provided information, and was very professional both in performing the maintenance service and communications with me.
I highly recommend Colonial Pest Control.

Excellent service!
Londonderry, NH
Service was great, had sprayed for carpenter ants a week ago and there are lots of dead ants all over the place, so I’d say it’s working well. Look forward to having yearly service done.
New Ipswich, NH
Colonial has been our pest company for over 20 years. I have been absolutely 100% happy with their performance during that entire time. They just did our semi-annual prevention treatment and as always, this technician was just as professional, thorough and careful as all the others over the years. I recommend them to family and friends and many use their services now. I continue to be a loyal customer and continue to give them my highest recommendation. Thank you Colonial Pest for all you’ve done to protect my home throughout the years.

East Kingston, NH
I was experiencing a LOT of ants recently. I contacted Colonial Pest Control and Scott came out the following week. He was extremely thorough, personable and was very respectful of my property. In addition to the spraying and fumigation, he provided me good advice going forward to eliminate this problem. I have not seen one ant ANYWHERE since Scott left. I am VERY pleased for choosing Colonial Pest Control.
