"…the best experience of my life in calling an exterminator. Sean is a great guy. Honest. Avoids toxins. Smart. GreenHow is what you should want to deal with pests."
Max, Cambridge, MA published on greenhow.com, 2026-08-19 Reported
"I have kids and pets so I wanted to avoid the crazy chemicals while still getting rid of the ants that had raided the cat food bowl and then made them selves at home in our bathroom. GreenHow was easy to deal with, prompt, and quickly found the source of my ant problem… and got rid of the ants. They are now my pest control company of choice!"
Michael K., Arlington, MA published on greenhow.com, 2026-08-19 Reported
"Sean Grenhow has without doubt the best of business ethics. He came on time. He was intrepid in finding the problem, did a thorough search, gave me lots of information – and good news- charged me not one penny and left after a good 20-25 minutes. I recommend him and his extremely knowledgeable service wholeheartedly."

These are the Solvo pages that number this company. A page can list the company even when the service-area section above does not, because the two lists answer different questions.
