East Patchogue, NY
This is in response to Knockout"s reply to my review. There were never many people going in and out of my apartment. Before, during, and after the extermination, the only person that came into my apartment was your worker. And by the way, I did not call the police so I don"t know how you can write that they called you. If I had a video, photo, or audio of the theft by your employee, they would have been notified. I would base my life on the fact the your employee STOLE my jewelry!
East Patchogue, NY
The technician stole my jewelry. I had to leave my home on 3 different occasions and did not check my jewelry until a month later. I am basically bedridden and do not usually leave my home. Half of my jewelry was stolen. I called and complained but he claims he did not take anything. I would not allow this company, which was sent by my building management, to ever come in my home again!

There is no evidence to support this review. We did get a call from this tenant. We worked with building management. We suggested she call the police. The police did call us, but never interviewed any of our office or technical staff. There were many other people in her apartment between the time we provided service and the time she reported her jewelry missing. Our technician has been with our company more than 10 years and is an exemplary employee with only accolades from clients as evidence of many reviews on our company web site in addition to Angie’s List reviews.

Farmingdale, NY
I had what I thought was a rotted board in my living room floor and suspected termites. I did not find any evidence of them in my basement but I called Knockout to be sure. Well they found them I did not look near as carefully as they did. I went ahead and got the treatment and hopefully in 2 years the termites will be completely gone. They explained the life cycle of the termites and how their product works to kill the nest. I was very happy with their service and would call them again if need be. TonyF.

Was very happy with the service and all the peo0le i cam in contact with at ‘nockout. Only wish there was some type of warranty or guarantee for the service.
Brooklyn, NY
So far so good! Very professional and friendly, well-dressed pest technician. After about 4 days since treatment, I haven't seen any bug, and I had a pretty bad infestation, much to my surprise. Knockout seems to be quite legit so far, and I would highly recommend them. Their yearly plan is reasonably priced and I plan to continue to use them for my (hopefully decreasing) pest needs.
Hempstead, NY
It’s been three weeks so far so good.
Garden City, NY
Very professional service.
Great Neck, NY
We're very happy with the job your technician did. He was on time and explained what he was going to do to get rid of the bees nest. He came back a second time to re apply and that did the trick. No more bees.
Great Neck, NY
The serviceman who came to take care of our bee infestation was very professional and knowledgeable. Just by looking and listening intently he found the nest (which was in a totally different place than we had assumed) and treated it. Haven't had the problem since.

Merrick, NY
We are very happy with knockout pest control. For years we have used their sentricon system for termite control, but recently we had a wasp infestation outside our front door. Not only did knockout solve our situation at the front door, they checked the entire outside of our house and found a second hive on our roof. They were thorough and very attentive. Thank you.

I have a 130 year old townhouse in NYC and have had various extermination needs over the years. The ONLY people I call are Knockout Pest Control. Their service is fast, thorough, and professional. They fix the problem correctly the first time and are very accommodating with scheduling. I cannot recommend Knockout high enough!

I couldn't be happier with the service we received. The technician, Christian, was so friendly and courteous. We had a wasp nest that was very active. He made sure no one got stung and offered advice for us to follow to make sure we didn't get stung after he left. I would highly recommend Knockout to all!
