Pest Control Services in Chelmsford, MA


Chelmsford is a growing city with more than 34,000 residents living about 24 miles northwest of Boston. Originally a great farming community in the 1800s, it served a critical role in the Industrial Revolution as it eventually became one of the first large-scale factory towns in the United States.

For centuries after, Chelmsford remained a popular place for many well-known people and buildings. Ralph Waldo Emerson opened a school there in 1825. It was also the birthplace of the first school for the deaf in 1866. Additionally, the Chelmsford Spring Co. opened in Chelmsford in 1901, and was acquired by Canada Dry in 1928.

Chelmsford’s climate is average compared to the northeast, where summers are warm and humid, and winters are cold and windy. However, with this northeastern climate often comes a variety of pests that Chelmsford residents run into throughout the year.  


As natives to the Boston area, Greenhow Pest Control has seen everything when it comes to pests. Whether it’s mosquitos, rodents, or other infesting insects, Greenhow has a safe, comprehensive, and extensive approach to eradicate them from your property—no matter the time of year.

  • Pest Control

    Small pests like insects typically come into homes through small openings, like cracks and crevices found around doorways or foundations. But whether it’s roaches, centipedes, crickets, or something else, Greenhow’s got your back when it comes to controlling pest populations around your property.

  • Lawn Care

    Your front lawn is the first thing you see when you pull into your driveway, so it’s natural to want it to always look its best. But with elements like unwanted pests, harsh weather, and soil issues, it can be hard to keep your lawn healthy year-round.

  • Mosquito & Tick Control

    Summertime is a treasured time for many families: School’s out, the days are longer, and the temperature’s warmer. However, two things can ruin any summer day: mosquitos and ticks. Luckily Greenhow can treat your property with family-safe products so that you don’t have to worry about these annoying pests for the rest of the season.

  • Plant Health Care

    Although beneficial to the environment, pests like beetles and caterpillars are notorious for destroying gardens and plants. Even worse, it can be a challenge to eliminate these pests without harming your plants. The good news is that the pros at Greenhow can safely eradicate these pests and keep your plants looking their best.

  • Rodent Control

    Rats and mice are some of the most problematic rodents that try to find their way inside homes throughout the year. They typically set up a shelter in attic spaces or empty wall spaces. They can cause significant damage by chewing on wires, ruining infrastructure, and leaving bacteria-ridden feces behind.

  • Termite Control

    Termites are some of the worst pests a homeowner can face. They populate into the thousands, and, unfortunately, their infestations often go unnoticed for several years. They can ruin your home’s infrastructure, which could cost thousands of dollars to eradicate and repair.

Boston Local, Cured My Ant Problem

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!

I now have a go-to exterminator!

They came out very quickly (one business day from when I called), were thorough in their investigation, and gave us an incredibly reasonable quote for pest control for other “guests” that we have like carpenter ants.  I was very surprised at their low initial and quarterly costs compared to their high level of service and commitment to using natural products.
– Kathy R., Woburn, MA

Great Service - Super Smart.

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.
– Alexandra H., Newton, MA

Honest and Smart

…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.
