We used Greenhow to deal with a large wasp nest in our back yard. We already use Greenhow for lawn treatment, which has been very effective. Luis was on time, courteous and seemed very expert in his work killing the yellow jacket nest.. He explained patiently and clearly what he was doing, what product he was using and what to expect over the next 24 hours. He also surveyed the whole back yard to see if there were any other nests or issues. We appreciated this very professional service.

Thank you so much for this — and for being a Greenhow lawn customer as well! It's always great when we can take care of multiple needs for the same household.
Yellow jacket nests can be a serious situation, and I'm glad Luis handled it the right way. I like to hear he was on time, thorough in his explanation, and proactive enough to survey the rest of the yard for anything else that might have been out there.
I really appreciate you taking the time to share your experience, it helps us learn and grow, and look forward to continuing to take care of your property!
Pest wishes, Sean Greenhow
Our lawn was all dried out and filled with weeds last year. This year it looks great. Ross has been super helpful and is very knowledgeable. I've also used Greenhow for wasp nest removal. Everyone there is friendly, knowledgeable, and professional. Highly recommend!

Thank you! Going from a dried-out, weed-filled lawn to one you're proud of in a single season is the kind of turnaround we work hard to achieve.
Ross is a tremendous asset and the leader of our lawn care team. His knowledge and personal investment in each customer's property make the difference,
Glad our team was able to take care of the wasp situation too! We appreciate the nice review, my business depends on them to grow, and look forward to keeping things looking great this season and beyond.

I cannot recommend this company enough! I discovered yellow jackets flying around my roof and property and called GreenHow out for treatment. From start to finish, their customer service was top-tier—professional, responsive, and incredibly thorough. What impressed me most was the technician, Rob Ronan, extensive knowledge. He didn't just spray randomly; he walked around the property with me and precisely identified and treated four separate yellow jacket nests that were working their way into the house through the siding. He used a specialized crack and crevice dust application combined with a targeted residual spray on the entryways and landing areas to make sure the job was done right the first time. On top of that, they located, treated, and completely removed a small bald-faced hornet nest hidden in the bushes in my backyard. It is rare to find a company that combines this level of advanced pest knowledge with genuine care for the customer. If you have any bee, wasp, or hornet issues, look no further!

Thank you so much Kim for the feedback on Rob. He is a great part of our team and I am happy to hear his work met your expectations. I appreciate your business and your review!
Highly recommended. We were noticing frass on our back porch but couldn't determine the cause. We were worried that it might impact the structural integrity of our porch of our multi-family building. Thank you to technician Wesley for coming out, investigating the problem, providing advice, and not making a hard sell. Wesley's honesty and straightforward approach makes me want to do business with Greenhow now and in the future.
Response from the owner · 3 months ago
Thank you so much for the kind words! Frass can definitely be alarming, especially on a multi-family property. I'm glad Wesley was able to get out there, investigate thoroughly, and give you an honest assessment. That no-pressure approach what I want to hear. Wes and I would rather earn your trust with straight answers. It means a lot to hear you appreciate it. We look forward to being your go-to when you're ready! Welcome to the Greenhow family! - Sean Greenhow
Moving from California to Boston, termites were not something I thought I’d have to continue worrying about. I was wrong!
We scheduled an exterior service about a month or so ago. Alexis went above and beyond in his inspection of the property. Unfortunately he discovered termites but fortunately we then knew we have to deal with the situation.
In the follow up Termite inspection Wes confirmed Alexis’ findings and did an extensive search for more evidence of termites. Fortunately it seems like they have not made their way into the house. Wes returned to install the termite prevention system and did a fantastic job including a very thorough overview of everything that was being done and why.
We are so happy that we are in such good hands. Everyone we have dealt with at Greenhow affirms the decision to work with them. While this is not necessarily a fun thing to deal with the experiences we’ve had to date have been confidence inspiring.

Joshua, thank you so much for taking the time to share! Welcome to New England! You're right that termites are not something most people moving from California expect to encounter here, but unfortunately they are a real concern in our area.
I'm really glad Alexis caught the activity during his initial inspection, and that Wes was able to confirm the findings, complete a thorough follow-up, and get the prevention system installed. That's exactly the kind of careful, communicative work we expect from our team, and it's genuinely rewarding to hear that it came through that way for you.
We're happy to have you as a customer and look forward to keeping your home protected for years to come.

We were outside working in the yard when we saw a tons of termites swarming on our basement window.
We knew we were in trouble. Our first call to GreenHow; we called them because a year ago we had trouble with mice and they gave us some helpful advice for free.
They came out that same morning and did an inspection, finding signs of termite infestation in the basement that I had missed. Sam explained everything in detail and we signed up for service.
Two days later Wesley came out to install the termite bait. He clearly knew what he was doing and was super friendly, letting me tag along while he installed the bait, explaining everything as he went and answering all my questions in detail. As a homeowner that expertise and willingness to explain makes a huge difference.
Having termites stinks, but our experience with GreenHow has been great!

Thank you so much for taking the time to share this — and for trusting us with your home, twice now! I am so glad the advice we offered during your mice issue last year earned that first call when the termites showed up. Discovering a swarm is never a good day, so we made it a priority to get out to you that same morning.
I will pass your kind words along to Sam and Wesley. Taking the time to walk homeowners through an inspection and explain every step of a bait installation is exactly the standard we hold ourselves to — your home is a big investment, and you deserve to understand what's happening with it and why.
You're right, having termites stinks! But we're grateful we could turn a stressful situation into a positive experience. We'll be keeping a close eye on those bait stations, and if you ever have questions along the way, don't hesitate to reach out. Thank you again for the opportunity to help you take care of your property. - Sean Greenhow
Robert was fantastic! He recently serviced our home and went above and beyond to make sure everything was taken care of.
He removed webs and debris around the perimeter, treated the foundation for carpenter ants and other insects, applied granular bait to the front yard, and safely removed both a yellow jacket nest and a bald-faced hornet nest from the side of our house.
What stood out most was Robert's professionalism, attention to detail, and friendly attitude. He took the time to explain what he was doing and made sure we were comfortable with the treatment plan.
We couldn't be happier with the service and highly recommend Robert and the GreenHow team!

Thank you so much for your thoughtful review. We’re so glad to hear Robert provided such thorough and professional service during his visit. His actions: taking the time to explain the treatment plan, address the issues around your home, and make sure everything was handled carefully is exactly the level of service we strive for. I (and Rob) truly appreciate your kind words and your recommendation of Robert and the Greenhow team.
Only wonderful things to say about Denis. He is kind, respectful and responsible. On his first visit he explained the world of termites and patiently answered all of my questions while searching for the source. His second visit was equally as pleasant, doing exactly as he said he would, further explaining and answering questions and making a frustrating situation as easy as possible. Many thanks and appreciation!

Thank you very much for the great review and the feedback on Denis! It means a lot that you take your time to let us know what we are doing well. I am excited to share this with Denis.
Ever since we started working with Greenhow we no longer have a pesky mice problem. My Greenhow tech Luis is great at his job, efficient, and very kind. Always happy to have him service our home. Thanks!
