It was an easy process- I sent pictures, he confirmed that it was yellow jackets, and in under a day, literally 20 hours later they had come and treated the problem. I cannot recommend them enough! Personable! Professional! Affordable! Fast! LOCAL. And a family business I'd support if I ever have a pest issue again. (Which I will, this is rural New England lol)

Well we are now dealing with bats and mice with no knowledge of where they are getting in because he said he didn't see any points of ingress. Luckily we were referred to someone new who is taking care of it. I bet he's great at pest control for insects but if you have mice and bats look elsewhere for services.

The guy who came out looked around and saw some dead ants, and checkked my sills in trhe basement. He said to give the Spectracide a few days to do it's thing and if I saw ants in a couple weeks to call. No charge. That's pretty awesome service. He didn't charge me because I had done the job hahaha. Now I've got ants that Spectracide won't reach, and guess who I'm gonna call? Groton Pest Control.

We have put everything food away into bins and we are very careful about what we're leaving out. Even down to the food for the dog has to be put away. You definitely do not get what you are wanting with this company. If you want dollar traps from the dollar store then you have come to the right place. Every single one of our traps has broken and the mouse is able to get out. They say they will be back. They don't come back for weeks and they don't even bring the stuff. We have never had a problem with an exterminator before but this one is something else. If you have dogs they don't really care because they'll leave those traps everywhere

This is not a company you can rely on…read more We spent over $10K getting bait stations and squirrel guard installed which went well. They were supposed to come once a month to check for pests and deal with them. Unfortunately, they do not seem to have enough techs to service all their customers. They "cancelled" the second monthly service without informing us. When we asked when they would be out to spray for ants they said we were not covered for ants. This is not what we were told when we spoke to the salesman. For $175 a month you would expect the most destructive pest would be covered. I can't recommend this company.

He guaranteed the spray for 90 days, so if there are any issues within that time frame, he will come out and respray for free. Great find on Yelp! Thanks!!

He is incredibly knowledgeable--not just about mice, ants, bees (including every kind of bee), and even rats--we've unfortunately had them all living near a pond. He takes the time to explain things, and you can tell he genuinely enjoys what he does. He's also just a great person. On his last visit, he had finished up and was heading to his truck when he spotted a stunned baby bird sitting in the middle of the street. Without a second thought, he stopped to help. We moved it somewhere safe and gave it a little water, and before long its parents came back for it. It had nothing to do with pest control, but it said everything about John.
