So far so good. Lots of dead bugs on the floor, but still see some flying around.
Garden City, NY
From start to finish Knockout was awesome. We had in ground wasps and I was nervous for my small child and dog. Knockout came out within a few hours. Curtis -the technician-was awesome, quick and efficient. We were quickly and comfortably wasp free.

New Rochelle, NY
The jury is still out as they just started a month ago. I called them because I had a mouse due to construction next door. The man came and sprayed the counter and put some granules around the base of the house. Man never went into the basement and then told me to get steel wool and spray foam to put around the microwave soffit myself. Yesterday I found a bunch of ants in my kitchen. Hmmmmm. Shouldn't that have been be included in the annual protection?

Knockout Pest Control is the BEST! I had an emergency at my house with yellow jackets and they showed up within the hour.. Michael was the BEST! He was so professional and knowledgeable and did such a great job! We are very grateful for his service and will only use this company from now on!! Thank you for all you did to help us in this very scary situation..

The second vist did the trick. A different chemical was used to kill the bees. Thank you.

I used Knockout for a bedbug infestation. Dee was very helpful, explaining all my options and the process, and very patient answering my many questions. They were able to schedule a canine inspection the same day, and the treatment two days after. I opted for the heat treatment with spraying. While it was expensive, it worked! The technicians were very professional, and one very kindly helped me put on a mattress and boxspring cover (while in a very hot room!) which was above and beyond. We had another canine inspection one month later and I'm very happy to report that the bedbug problem is gone! I would highly recommend Knockout Pest Control for bedbug treatment. - Liz.

Ronkonkoma, NY
I would recommend knockout pest control.
They booked me an appt. the next day, were here early and took care of a yellow jacket nest around the window flashing.
It has only been 3 days but, I haven't seen a single yellow jacket around that area!!!
Optimal results, 14 days are needed but, so far so good.

I was not here for the service itself, so I cannot speak to that. But the customer service on the phone was excellent. Whether it was effective or not remains to be seen.

We are very pleased with the knowledgeable and efficient way our pest problems were handled.
Port Jefferson, NY
I have had two different technicians and both were great. They take the time to look for all entry points and do whatever they can to prevent bugs from coming in. I had a big issue with carpenter ants and earwigs and the results were almost immediate. I quickly called to get on a yearly contract and it's money well spent. Techs are very nice and knowledgeable and calm the fears of this bug phobic lady 👍.
New Hyde Park, NY

Hicksville, NY
Technician Curtis was prompt and professional and I appreciated his suggestions.
Long Beach, NY
Still having issues with fleas. They came yesterday and the fleas are worse today. They won"t come back until Tuesday. Rather than admit they possibly missed the side of the house and make this right sooner, they try to mansplain exterminating to me and how it couldn"t possibly be their fault.

Then, since they know the conversation didn"t go well, oddly I don"t get a request to review them any longer. So strange.
Elmont, NY
Anyone searching out pest control combined with excellence in actually listening to the customers needs/concerns
KNOCKOUT IS FOR YOU! Sean took my initial call, I explained my need for pet safety & green products.He sent Michael who was thorough & professional, this company is premier from start to finish. Thanks Knockout! Its been 3 weeks since treatment that I'm writing this review complete confidence in their integrity & service.

Long Beach, NY
I had an issue with the business and posted a one star review. Within hours of my initial communication they ensured me that my contract would be honored. Five stars all the way.
Long Beach, NY
I signed a one year contract based on the information I was given that if I had to retreat for fleas it would be 95.00 per treatment. Knock out, unlike other companies, requires the full year contract paid up front (other companies are month-to-month) which I paid. Today, I called to have a second treatment for the fleas as they are back on the side of my house (less than a month later) and I was quoted $150, a fifty percent increase in price.
I was happy to pay the $95, as that’s what I was told I would pay every time when I signed the contract, but to increase the price after the contract has been signed for a full year is abhorrent. I was told they would honor the price this time but if I need it again (which I might because the fleas are die to an animal that died under my house) they would charge the $150. I would have never signed a contract with them if this was the case, because it’s more cost effective at that point to use a company that charges more for the contract but includes fleas. I have 11 months left, but unless something changes, I will not be signing another one, nor will I recommend them to anyone I know.

As we discussed we will honor the price that you were given at the time you signed up for the KO12 contract. The price will be in effect for the length of your contract. Thank You for your business- Knockout Pest Control
