quick to sign a contract...then slow to followup. I have a total 6 houses with you and am thinking of cancelling all contracts and starting with another pest control company.

Knockout came right away took care of the problem. Found the source quickly and I was very happy with the results. The gentleman who came to the house to take care of the nest was kind and very helpful.
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.

So far, so good. Mr. Swanson seems to have done a thorough job. No roaches seen, but now we do have what appear to be ants that hop. New to me. (It never ends, right?)

East Norwich, NY
I am new to Knockout Pest Control and signed up for the year plan. I'm learning more about what is and isn't covered but seems to be a good value. I've had two visits. The first tech was nice but didn't explain anything to me about the process. I was looking for information on the plan. The second tech offered more information on the process and what he was doing and also what is include in the plan.

Excellent professional service.
Merrick, NY
Excellent trusted timely service.
Brooklyn, NY
I've used them before and had good luck but this time it has not solved the issue (with ants). I just called them and was told to give it more time- but it's already been 4 days. In the past, it has not taken that long to get results (with other kinds of bugs) All she told me is in two weeks to schedule for them to come back- which she informed me that I would have to pay for again. Nope.
Roslyn, NY
Very satisfied so far. Will see by next week if any problem is resolved.
