Nesconset, NY
My initial review of Knockout, from the first call somehow got messed up, and apparently something negative was checked off. NOTHING could be further from the truth. The phone call, the help, the scheduling, and the actual service were all perfect. I'm so sorry if something else was inadvertantly checked.
Quogue, NY
Joe was very knowledgeable, courteous and professional. I would highly recommend him and Knockout Pest Control.
New York, NY
I only had your service once. I'd been seeing some bugs in my kitchen and. the exterminator for our building was not effective. I called you and one hour later a lovely guy came here and treated everything and I have not seen a bug since. I am thrilled. I'm just trying to decide how often to use your service.
Uniondale, NY
Great service.
Roosevelt, NY
I have a mice problem and it's been day 5 since the company came to administer treatment and there is still no results. It's so scary to still see those creatures running around inside my house as if they own it. My biggest concern is that I just had my baby and I don't want them messing around with my baby's things. I even caught them running on the kitchen counter tops more than once. These are the main reasons why I called in the professionals to get rid of them but still no improvement!
New York, NY
Yes we are very satisfied with your services.
Stony Brook, NY

I have been using Knockout for several years to deal with a termite problem. Since starting to use their service I have been termite free. I recently called about another insect related problem and they had someone here within 24 hours. The service people are professional and always do their best not to disturb me or my household.

Astoria, NY
I’m very pleased with the service of knockout pest control. The technician was very pleasant, very professional, very nice and helpful. I definitely got some peace of mind as a result of his visit. I do not currently have an infestation but I still signed up for the annual contract as a preventative. It’s worth the price to know that my home is protected.

Hewlett, NY
We have been using your company since the 1970's and have always been very happy and satisfied with your service. The last service we had was for ants in the kitchen and the service man who came was Edgar. He was knowledgeable, courteous, wore his protective gear and was extremely pleasant to have in the house and outside the house.
