I called about issues with bees in my house. Within hour someone was here to address issue. Joshua who was here is awesome. He explained what he was going to do and said he would follow up with me in two weeks. I highly recommend Cornerstone Pest Control.
Epping, NH
Sydney in the office was an absolute pleasure and was able to get someone out to our ground wasp problem the same day. Amazing!!! Joshua who took care of the problem was just about the nicest guy in the world. The price was very fair and the stinging squatter were gone the same day. I definitely reccomend and will use this wonderful business again.

Josh was everything you would want in a service man. He was knowledgeable, friendly, on time, explained everything well. So much happier with Cornerstone than Pest End. Julie Vaux.

We couldn’t be more satisfied with the service from Cornerstone! The technician arrived promptly, was extremely professional and handled our wasp problem beyond our expectations! I would highly recommend Cornerstone to anyone needing pest services!!!!
Raymond, NH
Josh was amazing. The pricing is awesome. Came right and gave me a quote and hired on the spot. I loved that they gave me a contract and explained everything right away. I've used other companies that didn't send a contract and would inform you over the phone of things not included in your pest control and then charge you. They should learn from cornerstone!

So far, so good with the issue of the black ants. Activity was greatly slowed within a couple of days. We've only seen a few ants outside and no live ants in the basement.

Wilmington, MA
We had an excellent experience for mosquito/tick spraying. Our property abuts woods, and other companies we have used just did a typical perimeter spray, and then we would have to call them back once the mosquitoes inevitably came out from the woods. The tech that came to our property recently spent WAY more time tending to our land than other companies have in the past, and he even went a good 20-30 feet past the wood line to spray the brush and trees in the woods. We appreciate the thoroughness of the work!
