Preventative Pest Control Services For Any Situation

Pest Authority of South Rhode Island is proud to provide the Westerly, Rhode Island community with high-quality, affordable pest control services that really work. We know how frustrating it can be to live in a home that’s infested with pests and trying to get rid of them on your own can feel like fighting a losing battle.

Pest Authority isn’t like other pest control companies in the South Kingstown, Rhode Island area. We have a no contracts and no commitments policy that allows you to cancel any time without penalty, while other companies will make you sign an annual contract before even getting your first treatment. Our 100% satisfaction guarantee means you can trust that we’ll put in the work to get your pest problems solved.

Our incredible Barrier 360 treatment makes comprehensive pest control an affordable option for more of our neighbors. Barrier 360 prevents 13 common pest infestations with the same treatment.

No Contracts. No Commitments. No Pests. Guaranteed.

Instead of treating a single pest like many treatments do, Barrier 360 works for all the following pests:


Carpet Beetles








pill bugs



If pests do get inside your home in between Barrier 360 treatments, Pest Authority will send a technician to your home as soon as possible to perform additional interior treatments at no extra cost. If pests return, so does Pest Authority.

We also handle a range of other pests and problems, including:

Bed Bugs



Wasps & Hornets

We are so proud to serve the Westerly, South Kingstown, and Richmond, Rhode Island communities. You should never feel unsafe or uncomfortable in your own home due to pests, and we’re here to make sure pests never invade your home. If pests do get inside between Pest Authority treatments, simply call, and we’ll retreat your property free of charge. No Contracts. No Commitments. No Pests. Guaranteed.
