The technician I believe his name was Edwin, was 100% professional explained what he was going to do before the job started, and went through what he did after the job was completed. Explain thoroughly everything that I was signing. Recommend them highly.
Smithtown, NY
The gentleman who came was very nice. I have a mouse problem. He put traps around but I think you should come back sooner than two weeks. I had a lot of mice that is why I called you. I spent $500 and I ran out of supplies almost immediately. I called but had to go out and buy my own supplies before you made an appointment to come back. That was a little disheartening. K.

Levittown, NY
So far so good.
Shirley, NY
I was very happy for the service I received. I would be happier if after 2 weeks and one day I didn’t wake up to more bites. I do feel once you have the bug problem, no matter what anyone does, you’re never relieved of the problem. They did do their job, exactly what we were told, and now I don’t know what more to do.

Brooklyn, NY
We've recently been having a mouse issue. We called Knockout based on its many positive reviews on Angie's List and were able to schedule an appointment for the next day. Our technician, Christian, showed up on time (and even gave us a head's up call on his arrival time). He carefully checked our space (including our cellar and tenant's unit) and place bait and traps throughout. He offered good advice. We have to wait two weeks to see if there's any improvement in our mouse situation but our fingers are crossed!

Rockville Centre, NY
Alin was terrific! He was very professional and went through the entire house very carefully. I'm fact while he was placing glue traps in a small Crawl space he noticed a leak in one of our pipes and suggested we get a Plumber to check it out so the problem didn't get worse. My husband and i were very thankful for that information.

Saint Albans, NY
The technician was courteous and thorough. He explained what he was doing and why. He seemed to enjoy his job and did not seem to be in a rush. Will definitely recommend him.
There was a noticeable effect on the roaches post treatment but as recommended, will wait until the 2 week period has elapsed before I can truly formulate my conclusion.
Great Neck, NY
It is too early to determine how effective the treatment is, but the technician was very thorough in applying the product, wore protective booties while inside my home, and he was very polite. I am hoping to see the crickets will be exterminated. I will give a higher rating for referral, but need to see results first.
