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! read more

Greenhouse was the only company of those who responded to my inquiry and offered to give a quote and recommendations after seeing my property. The quote was a little above my budget, but they were friendly and knowledgeable and answered all my questions. i would consider and recommend them for their integrity and honesty. read more

Easy to communicate with. Came by the house for a free evaluation and gave us some great tips on how to deal with millipedes, although the action to take was about landscaping which is out of scope for their services. read more

Donna, your office manager, is always so friendly, and very helpful. She makes me feel valued as a customer. And Danny, our technician in Marshfield, knows his business well, and is always extremely kind and professional. In an industry where there is always competition, Greenhow rises above. read more

Denis the termite expert did a very thorough inspection of my home. He's very professional, knowledgeable, and very nice too. I am so grateful that this company was recommended to me, and I recommend them as well. read more

I messaged GreenHow about some (what we thought were at the time) wasps and they came out a few days later to take a look. Ross on the team was so friendly and explained that they were actually ground bees and were non-aggressive pollinators. We're going to follow their advice and discourage them from nesting where they are instead of spraying. I just wanted to thank them for being so friendly and professional and I would most definitely call them again with any other pest issue we encounter. read more

Denis came to check for termites. He was on time, wore a mask, told me he was vaccinated and did a thorough inspection, all the time telling me what he was looking for and why he was looking in certain places. He clearly knows what he is doing and is very professional and personable. Happily, he found no instance of termites. I mentioned that I had been getting some mouse activity in my bulkhead and he did another thorough inspection in the basement, kitchen and attic. No inside activity and Denis showed me where I needed to fill some gaps in my bulkhead. The inspections were free and no treatment is needed. If anything does develop, Greenhow and Denis will be my first call! It is so refreshing to find a company that isn't just a hard sell and is dedicated to excellent customer service! You can trust this company. read more

I was having work done on the exterior of my home. Turns out we had quite the infestation of wasps. GreenHow was able to squeeze me in. They were at my house the next morning taking care of the problem. I was very happy with how reasonable the cost was and the quick response. Definitely recommend. read more

Great quick service and very responsive. Would use again and recommend to others. Thank you!

They are responsive and give you good options at the initial visit. They recommended an initial service and they come back monthly for our rodent problem. Don't have any issues with them. read more

The employee that came by, I believe his name was William was amazing. He was helpful, thorough in explaining what he was going to do and made our wedding night one where I didn't see a single bug the entire night when normally they're all around. Our field was about a football field size plus another acre so I was not expecting nearly as awesome a result as we got. I can't explain how happy we were with the service and would recommend it to anyone. Their spraying is organic so it's safe for pets and children as well which was really important to us. I couldn't be more pleased and we will be using your service next year to help deal with the mosquitoes around here for sure as I haven't seen one since the spraying two weeks ago. We are thrilled. read more

I just had Danny around to sort out a wasp problem I had. They were quick to respond to my contact-us form on their website last night and came out the next day. They were able to treat the area and gave me really good advice about an unrelated question. I liked the explaination of what they were doing and why, will definitely use again :) read more

GreenHow definitely surpassed my expectations. They were quick to respond and made everything super easy. William was sent over for my pest problem and was super helpful and very informative. On top of all that the pricing was very reasonable. All in all I was very happy with my experience. read more

Sean is great. Sent message via yelp and he responded immediately. Sent his crew for free inspection. The guys sent a quote immediately, we scheduled them to come out and install the system and the did. The office support is really nice as well. read more

I have been using their services for years. There's a tribe of bees that comes back like clockwork, even though we've had carpenters to plug up all the places they used to live. One treatment from Greehhow in May solves the problem until the next Spring. But what I really like about them is that everyone, from the person answering the phone to the technicians to the management has always been intelligent, knowledgeable, helpful and friendly. read more

Greenhow was recommended by a relative to look into a problem I had with moths. The gentleman who came (on time) was professional, knowledgeable and very helpful with our problem. I would definitely recommend Greenhow to anyone looking for solid professional help in this area. read more

Professional, incredibly quick - they treated the same day they came out to their free estimate! Nicest people too! Very knowledgeable

We have a rodent problem and so far we have been very happy with their service. they came recommended by a good friend of mine in the same town. Donna and Sabrina in the office are very helpful and personable, and Danny who comes out to the house Is great. He found all the entry points were the rodents were getting in and set traps all around the house. We definitely saw a decrease in activity as I have a "rat cam" checking in on where they are. Danny is polite, professional, and is very patient in answering all of my many questions! Highly recommend. read more

I love everything about Greenhow. When I suspected termites in our home, I called and they sent someone right out to inspect. The employee was thoughtful, thorough, and patient with me and my questions. This has been my experience with everyone I've spoken with at Greenhow- they are kind, informative, thorough, professional, timely, and easy to book (Donna who does the bookings is a gem over the phone). Not only that, but after signing on with them for termite and pest treatment (for which there are very reasonable prices), they sent a handwritten card in the mail thanking us for being a customer. Could not recommend them more! Great experience so far and no doubt it is the standard. read more

These guys are awesome. I had what I thought was a cockroach problem- Triple Yuck. They sent someone out to look, and instead of them trying to sell me something they identified it as a different kind of bug that will die on its own and not take hold in the house. 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. Never thought I'd have a go-to exterminator, but now I do. read more

We used GreenHow in Nov '20 and they didn't do very much. For $359, they inspected the house, inside and outside, and placed about 12 traps in "high traffic" areas. The traps didn't catch anything in one month so we canceled their monthly service (extra $79 a month). In my unit, the traps didn't catch a mouse until a few months ago. Meanwhile, the unit below me is having lots of mice, and the upstairs unit has seen mice too. We were really disappointed because of all the great reviews. A bunch of people said that they had small holes filled in. We didn't have any interior holes (around the radiators, appliances, pipes, etc.) or exterior holes (in our fill stone foundation) filled. We've just now contracted another pest control company that charges $375 to inspect, set traps, and fill all small interior and exterior holes, including behind the refrigerator and stove -- plus a 3 month warranty. They are also pet-friendly. Anyways, we feel cheated by GreenHow and don't understand why we got subpar service. The tech did not look at all the potential entry points into the unit and offered no suggestion or help in sealing them. read more

They came out on time, are professional and courteous. They helped us to get rid of the wasps that had moved into the vents in our house too. read more

Glad we found these guys. Organized, knowledgeable and they seem to hit that sweet spot of not over or under doing it.

We are truly grateful to have found this incredible local business! Matt and the entire team at GreenHow Inc are knowledgeable, super responsive and provided exceptional service resolving our mouse issue. We recommend them highly... 5 stars do not seem enough! They are truly first-rate, always pick up the phone (no waiting days for messages to be returned) and take time to listen to issues and explain solutions. Thanks Greenhow team! read more

After calling many firms who would not come on short notice or make an appointment for a certain time, I turned to yelp for recommendations. I was not disappointed. Sean was able to come out within a short time frame and was very knowledgable. The inspection was very thorough, and his knowledge went beyond pest-control, and included general house and home owner recommendations. He left us with a thorough report and we will have him back to take implement the recommendations soon. read more

Everytime I contact GreenHow about my needs for pest control they take care of everything quickly and make it easy on me. I've asked for their help (and I mean rescue) with hornets, mice AND rats! I also subscribe to their termite prevention program since I own a 125 year old house, and there have been zero signs of termite damage since they began 6 years ago. As someone with pets and child visitors, I truly appreciate the safety measures taken by the GreenHow team. I've recommended their services to many friends in the Boston area. read more

These guys were really determined to provide great service. They called to follow up and came back to fix a problem. I recommend this company. read more

"As good as it gets" is exactly what Greenhow deserves. Prompt 100% of the time. Proactive 100% of the time. Trustworthy...100%! Knowledgeable 100% of the time. And really great people to boot! My lawn looks great......and when it doesn't, due to our wonderful weather, Sean sends a technician out immediately. Thanks Greenhow! read more

Prompt, reliable, intelligent, easy to work with, responsive to concerns. And my grass looks AMAZING. Having cared for it myself over the years, and more recently with another lawn service, GreenHow really knows their business. read more

We have been extremely satisfied with GreenHow- their work and their outstanding customer service. Donna in the office is incredibly helpful. You never get a phone menu, she always answers, is friendly, and gets you whatever you need right away. Their employees are excellent- the same person comes regularly, he knows our house, the issues, etc. (With a previous company we used it was a different person every single time and we had to go over everything with them from the start each time.) If you do have a mouse, they'll even come to retrieve it free as soon as possible. They also do an eco-friendly spray for your yard ticks/mosquitos that I think worked really well. After they come you receive a summary of their work via email within 10 minutes usually. Just an all around reliable great company that truly cares about their customers. read more

Incredible. Sean was super helpful with my questions and was able mitigate my fear and concern of an infestation. Did not try to sell me anything, just answered my questions/concern in a very well educated and professional manner. I think we dodged a bullet, but if I ever need pest control, GreenHow will be my selection! THANK YOU SEAN! read more

I called and was able to get a same-day appointment for an ant problem in our dining/living room. Mike and Mike were fantastic; very knowledgeable and answered all my questions. They checked the rest of the house too which I would not have even thought of. Best of all, the ants are gone! Customer service was great, Donna too in the office. Would highly recommend. read more

I am SO satisfied with the service I received from Greenhow. Sean on the phone first, and then Steven in person, were so professional, thorough, and helpful. They took the time to educate me and talk through what a clothing moth infestation would look like (turns out, I don't have one, even though another company was quick to tell me there was a problem and it would be expensive to fix it). Their in-person careful inspection was free. The initial consulting on the phone and the email follow-up, all free, and responsive, and thorough. If we ever have any sort of pest problem again, I will call them first and only. Thank you! read more

I heard about GreenHow from someone online, and after calling a few different places, I was pleased to hear that they would 1) come out and look at my condo without requiring an entire condo account, AND 2) that they would look behind my stove to patch holes (a few other places said they refused to move gas stoves - um, not helpful if the gas pipe has a big gap around it!). Good news is that Sean came out within 3 hours! He was on time, friendly, and very informative. He was also quite sensitive to my ridiculous mouse phobia and prevented my seeing dead mice under my stove. GreenHow uses 'green' techniques to keep mice/pests out, and Sean has a few kids, so understands that pest control needs to be safe. I learned that in addition to mice, I have some sort of moth larvae growing in my kitchen and hallway ceiling edges, and that there are roaches. Wow, loving this new place we're living in. UGH. Sean listened to my melodramatic mouse history, explained how recent renovations could have made the situation better/worse, and checked out the basement. He then informed me that it looked like a professional had laid traps in the basement. Later, we found more traps in the kitchen (old ones and with lots of nast attached) that confirmed that another exterminator had already been in the unit. Being the good guy he is, Sean suggested I call this other exterminator and see if the condo has an active account. Which I did and we do. So...I realized I was basically already paying an (extremely ineffective) exterminator and, despite my prodding, couldn't get Sean to basically sell this other company out and convince me I should hire him. I now want to terminate the account with the other exterminator and hire him EVEN MORE - it is a pretty honest and nice person who won't take advantage of a naive homeowner who is afraid of mice. And, who will come out and clean things up, patch holes, and give a fair quote all for free. Since I have to get the whole building on board, I'm giving the other exterminator a chance, but I fully expect that we'll switch to GreenHow. And hopefully then I won't ever see Sean again because I never have another moth, roach or mouse in my kitchen. read more

Customer service was top-notch at Greenhow. As many times as I called with questions and trying to arrange services with my neighbors, everyone I talked to was very pleasant, friendly and helpful. Henry, who came to look at the trees, was super-nice and knowledgeable. Great overall experience! I hope I never have caterpillar invasion again, but if I do, I know who to call and who will help me get rid of them in a timely manner :) read more

A pleasure to work with. Showed up on time, knowledgable, personable technician. Excellent company.

Great company, great service. I called them to get rid of carpenter ants who had been coming annually into our house. They were prompt, professional, friendly, and cared about the fact that I didn't want pesticides around my kids, offering safe alternatives. Sean and his crew are a class act. read more

I also am very happy with Sean and the whole gang's services. They are very responsive and very tidy. What more could you ask for? I am actually from winchester, but it says I am from ct. read more

From the first telephone contact to the treatment carried out today, our Greenhow experience has been superb. Molly was friendly, polite and efficient on the telephone, and made a next day appointment for an inspection at our newly purchased property, which had some unwelcome sitting tenants in the form of carpenter ants. Megan carried out the inspection on a Thursday and spent at least an hour going around the property and quickly found two nests. I called Molly again, once Megan had finished her inspection, and made an appointment for four days later on the Monday to have the treatment done. The technician, Steve, spent another hour treating the house inside and out and took the time to explain how the product works and how long it should take to do the job. Molly, Megan and Steve were all very thorough, informative and polite and are a credit to Greenhow. Keep up the good work! Thanks to all the Yelpers whose reviews directed us to Greenhow and I hope this review helps someone else. read more

I am not sure of the persons name that came out to fix our problem, but he was amazing! We started having a mice issue and after weeks of begging my husband to call someone for help, he called Greenhow. They came out the next day and inspected the house to see what could be the issue. Traps were set in places my husband never thought of and holes in our foundation were filled. This is the best $ we ever spent! read more
