“General Environmental Services did a wonderful job. They did pest control. They were on time and cleaned up after themselves. I would grade them an A, and I have already recommended them to others.”
“They were excellent. They did pest control for me. They showed up when they said they were going to, and they did their job. The gentleman that performed the service was very informative and helpful, and he resolved the issue. I would give them an A.”
“They were very efficient. They came out quickly after I called them. They've been very good about leaving information every time they have been here. I would grade them an A+.”
“General Environmental did mass extermination. I would grade them an A+, and I've already recommended them.”
“I love those guys. They have done work for me in the past. They sprayed for ants at my house. They have also looked for termites for some of my clients, and they have had a positive experience as well. I refer all my clients to them. I would grade them an A+.”
“They were doing work for a client for a home inspection for pest control. I liked the timeliness of their response as well as the professionalism of their written report. General knowledge base and a good ability to convey the information to the consumer as well as set it up with me to get to the house were pluses. I would grade them an A. I couldn't say enough good things about them, and it was a positive experience throughout. It is highly likely that I would recommend them.”
“It was pest control. I followed the worker around the house, and he was very thorough. I asked him how long the product would last. He was a nice guy, the job got done, and we haven't had any problems from anybody. I would grade them an A+. I would definitely recommend them to someone.”
“They did pest control. They were knowledgeable and effective. I would grade them an A+”
“They did pest control. They showed up when they said they were going to, and I would grade them an A+.”
“They did general pest control, and I felt very comfortable with them. They were very informative, and they did what they said they would do. We signed an ongoing contract with them. I would grade them an A+.”
“It was a good experience. They did cockroach treatment two or three times. It's better now. I called them back, so they followed up, and they did exactly what I told them. They didn't spray the house the first time, but when I called them back they followed up and did exactly what I recommended. I would grade them an A+ for the good experience I had with them. I didn't have any problems. I would recommend them.”
“It was a very positive pest control experience. The people were nice and their treatment was successful. I would grade them an A+.”
“It was pest control for some kind of teeny, tiny ant. They guaranteed it for three months, and we haven't seen it since. I would say they were all very good, and I would grade them an A+.”
“They did a great job. I asked them what I needed to do to get rid of the pest problem. They came on time, and they did a great job. Everything was clear and gone. They were very nice and very honest. I really liked them very much. I would grade them an A+.”
“They did pest control for me. I called when I saw a mouse and they came the same day. They came multiple times to help me as I kept seeing them and needing to get more holes filled in my apartment. They were pleasant, polite, and responsive, which I appreciated. I would grade them an A.”
“We had some termites. They came right away and did what they were supposed to do when they were supposed to do it. They are good people. I would grade them an A.”
“They did pest control for mice. They were efficient, on time, and I've seen good results. Overall, I just think it was a good experience. The customer service was good. They explained everything that was going on and what they needed to do. I would grade them an A. I would very likely recommend them.”
“I first called them for a problem on the Friday afternoon of the holiday weekend, and they were very responsive. They didn't end up having to come out, but were able to set me at ease. It was very nice. I would grade them an A-.”
“They got rid of the stuff in my buildings. They were there on time and did what they said they were going to do. I was happy with them. I would grade them an A.”
“It was very nice. There was nothing in particular that stood out, but they were good. I would grade them an A.”
“They only did pest control. There were no issues, so it was good.”
“They were just doing pest control. They were nice, on time, and did what they were supposed to do. I would grade them an A.”
“They were doing pest control. They came on time, were thorough, and did not mess around. It was just a very efficient and thorough process. I would grade them an A.”
“We were just scoping out a rodent problem. I didn't sign up for any services, but I had the guy come out and do a brief inspection, which was more than I needed, I guess. It wasn't really any work, just looking things over for an inspection. He had good advice. He looked around and didn't see any trouble spots. I would grade them an A-.”
“They were great, and the mice were gone. I would grade them an A.”
“They did some exterminating of yellow jackets. Nothing stood out that I could say, but I would grade them an A. Because the season hasn't come yet, I'm not really going to be able to totally know whether the job was done until the weather gets warmer. Until now, it's been winter, and there are no yellow jackets around here in Massachusetts at this time. It's one of those things where in another month, if there are yellow jackets, I'm not going to be too happy because it didn't work.”
“The exterminator tech was good, and he did a good job.”
“They came out right away and they told me they would start the next day and were there that day. They followed up a week later to make sure everything was going right and put out more bait. Everything was above and beyond. He told me other things I could do to address problems, although there was no problem at that time. I would grade them an A.”
“I would recommend them, and I had no complaints.”
“They do my pest control. General Environmental Services has always been a great company to work with.”
“They are very diligent, and they are very competent in what they do. I was able to get some results.”
“They were responsive and always booked the work ahead of time. They showed up when they were supposed to and reported the work they did. If I ever had work out of the ordinary and asked them to come in, they would make an additional service call.”
“They do spring outside-the-house work. They're right on time, and they have no hesitation about coming back out if we have rain or if we don't think the pesticide is working the best it could. We put in the call, and they come right out and do it again for us. We wouldn't use anybody else. We had them in our last house, and when we moved from our last house to our new house, we took them with us. I would give them an A+.”
“It was great. We had no problem with them whatsoever. We had an additional problem last year, so they came back out and did some further work, and they took care of us. They were terrific. We had a lot of ants, and they kept coming back even after the first application. They came back out and took care of it. I would give the company an A rating.”
“It was a positive experience.”
“They came on time, as scheduled, and provided the service that was requested. We haven't seen any ants, and that's pretty good. I would give them an A rating.”
“They came, did what they had to do, and did it well. They did ant spray. I would give them an A rating.”
“They've just been a great service. They're reliable, they always show up on time, and we actually don't even have to be home for it, so I don't really have to deal with them. They do ticks and mosquitoes for me. I chose them because my mother had used them before. I would give them an A rating.”
“They're reliable, and it seems to be effective. They spray for ticks and mosquitoes. It's routine—about once a month. I chose the company because a neighbor was using them. I would give them an A rating.”
“They did what they said they would do and came when they said they would come. It's a yearly contract—a yearly spraying. I would recommend them to a friend or neighbor, and I would grade them an A.”
“When I sold my house, I had a termite inspection, and they treated for termites. That was a little over a year ago, but I sold the property. Everything was satisfactory. The job was done, and there were no problems. I moved out of the house, so I was unable to follow up on anything, but whoever came to the house was professional, and they did a good job. I would give them an A.”
“They're just easy to schedule and to deal with, easy to pay, and very clear. They handle their service appropriately. I haven't even been home when they've been there, and they come, they take care of things with my wife, and they leave. They just do pest control for carpenter ants. They come out once a year. I would rate them as an A.”
“They came efficiently when I called them. They focused on termites. I chose them because they were recommended. I would give them an A rating.”
“I like them. They're fine. I like one of the guys—he's an on-the-ball guy. They did termite pest control. I've had them around for a long, long time. I paid the initial expense when they drilled into my foundation and put in all kinds of pesticide. I've been happy with them. I would give them an A rating.”
“We had an ant problem a few weeks back. They were very professional and prompt, they did the job promptly, and it worked. There are no ants today. We used to go through another company, but they merged. I would recommend this company to family and friends, and I would grade them as an A.”
“I just think they did a good job.”
“They worked with me the year before last. They were prompt and did what they said they were going to do, and I was very happy with them. I had termites originally when I bought the place in 2010; I think I had them in that year, and then I had them in the next couple of years, but since then, the porch was taken down, and that's why I haven't had them. I have no complaints; I would recommend them. I would grade them as an A.”
“They showed up when they said they would show up, and they do follow-ups to make sure we stay on a schedule. Mostly ants were our biggest issue. We haven't had any issues since they started. I would recommend them. I would give them an A.”
“Everything was fine. He did his job, and he did it thoroughly. This is just a general quarterly service; they mainly take care of ants and set traps for mice. I used the company before it was called General Environmental Services. I would recommend them. It was a good job; it was fine.”
“I've worked with both the service and the personnel. They took care of general pests, including rodents and ants. I'd recommend them to family and friends. They're an A.”
“They were great. They show up on time, and they do like you ask them to do. They take care of mice and spray for carpenter ants. In fact, I'm going to call them tomorrow because I need a wasp's nest removed. I would give them an A.”
“They were great.”
“It was good. I haven't dealt with them in a long time. They took care of termites, I think. I would recommend them, and I would give them an A.”
“They did a good job, and I was happy with it. I would give them an A grade.”
“We just signed up with them. I have no complaints. They're personable, they seem to care, and they come on time. They're just professional. ”
“I think they were here last year; I think they just resolved our issues. We had chipmunks in our basement. I would recommend them—I would give them an A.”
“They do a yearly inspection for pests. They're just easy to get along with, and they come at whatever time is appropriate for us. I probably chose them because they also do the place where I work—that's where I first met them. I thought they did a good job there, so that was enough referral for me. I would give them an A.”
“They did insect and rodent control. I like them because I don't have mice or bugs. I would give them an A.”
“I absolutely had a positive experience. I would use them again—still use them all the time.”
“I think I'm expecting them to come back in the next month or so for a follow-up. I think they took care of the problem—they took care of carpenter ants. They were recommended by a friend. They were fine. I have no complaints, so I guess that's an A.”
“They're very responsive, they get out here exactly when I want them to get out here, and they take care of the problem. They do everything—they do rodents, they do bats, and they do bugs. I chose them over a different pest company because they're local. ”
“The guy from GES is wonderful. We like his personality and his thoroughness. We're very happy. We have them come back every year. He sprays for ants, and we haven't had any issues with ants since they started working for us. They've earned an A grade.”
“I'm very happy with them. I've used them for over 20 years. They are very thorough and very forthright with the evaluations, and they go from top to bottom with whatever needs to be done. They've done preventive work and some outside work for ants. I'd highly recommend them, and I'd absolutely rate them as an A.”
“Team GES has a very friendly staff. They're timely and very good at their jobs. The folks who do the work are very nice, and anyone I've ever spoken with at the office has been very helpful and kind. They do mosquito control—A+.”
“General Environmental Services has always been wonderful.”
“The guy who came out was excellent. He ran me through the whole process, explained everything very clearly and really quickly, and simply did a good job. He took care of ants for me; he just did spraying around the foundation and that kind of thing. There are no ants now. It's excellent, and we are in good shape here. I'd grade them as an A.”
“Team GES was great. I would highly recommend them, and we'd give them high marks.”
“I've probably been doing business with them since the early '90s. It's nice that they come on a regular schedule—I like that. They were here for ants, although I've also had problems with bees, silverfish, and spiders this year, and I have a lot of earwigs. I had some sugar ants. He sprayed, and I haven't seen anything since—A+.”
“I always have a positive experience with GES. I've used them for years. I have a year-round maintenance program, so they come four times a year. They're very friendly, they know exactly what to do, and I don't have to follow them around the house. They do the outside as well as the interior, the attic, and the garage. They're an A+ company.”
“We've been using them for a few years. They bought a company that was local and took over that service. They're pretty good; I have no problems with them. They said they would keep the bugs away, and they did so. They did pest control inside and outside the house. They take care of all the typical insects that you get in a rural environment without causing any harm to wildlife, such as birds. So far, they get an A from me.”
“I've used them a couple of times, and I've had a very good experience. They were responsive, and they did exactly what they said they were going to do. I had a termite problem, and they took care of it. I'd rate them as an A.”
“I've had the same guy for several years, and he's always done a good job. He just seems competent. He seems to know what he is doing, and he is very agreeable when I tell him what I'm looking for. He's satisfied all of my needs. Every year, he does my home, and I've had him do my granddaughter's home, too, mainly for ants. He sprays the inside and the outside. I would give them an A.”
“I've been with Team GES for a little while. The same gentleman comes, and he does a good job. The consistency works out well. He takes care of mice and ants. If somebody asked me about the company, I would recommend them. They should get an A.”
“We have a contract where they come out three times a year and check for critters. We don't have any critters, so I'm happy. I don't like to have strangers in my house, but it's been the same person. I guess it rotates depending on who's in the area, but it was the same two guys before they merged with somebody else. We used to use another company that was bought out by or merged with them. We like the consistency of having the same people. I would say they're an A.”
“Everything was great with General Environmental Services. I have no problem with them at all—they're great people.”
