Residential Pest Control Services in Southern NH and Northern MA


Our Home Protection Program is a residential pest control service that provides year-round protection and peace of mind from mice, rats, rodents, wasps, ants, spiders, and other pests that can find their way into your home or attach themselves to your residence.

Here’s how our Home Protection Program works:

Step One

A Cornerstone Pest Control Professional will visit your home for an inspection. We’ll locate all points of entry and create a custom plan to seal them off.

Step Two

We’ll schedule a time for our expert to put that plan into action, sealing off all points of entry, and taking additional precautions where necessary. We’ll also perform periodic treatments to help keep rodents AWAY

Step Three

After, we’re on-call for one full year. If intruders make their way into your home, call us. We’ll come out and perform any action necessary to keep them out.

Cornerstone Pest Control finds the source of every in-home infestation and puts a protection plan into action for peace of mind. We will work to prevent pest problems from recurring, so you can keep your home pest-free all year round.
