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.

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.
