Farmingville, NY
I couldn't be happier with the service we received. The technician, Christian, was so friendly and courteous. We had a wasp nest that was very active. He made sure no one got stung and offered advice for us to follow to make sure we didn't get stung after he left. I would highly recommend Knockout to all!

I was recommended to Knockout by a friend who knows the owner. I was torn on making my decision about which company to choose for my first treatment at a new home; I am so happy I went with Knockout because they’re service was stellar from the initial phone call w Erin to our first home visit w Andre ... they were courteous, friendly & most of all competent! Seems too hard to find that combo these days.

I talked to Dee. She was very helpful and informative. Helped me make the right choice of how to proceed in getting rid of bed bugs. First suggested that I have a specially trained dog come in to find out exactly where the bugs are. Fortunately the infestation was confined to just one bedroom (had recently gotten a new mattress !). I decided to go with the one time only HEAT treatment. Portable heater/fans are brought in to heat the ambient air temperature of the room to @ 130 degrees for over 2 hours (the bugs and eggs are literally dried up!). In addition they also applied a bed bud residual chemical treatment to all rooms. Saf, the exterminating technician, arrived exactly on time (7 a.m.) and was very friendly, polite and professional. He was very knowledgeable and well trained. He clearly explained what he would do and what to expect. In order to run multiple heaters, many power sources (some 220 volt) have to be tapped. Saf was well versed in how to safely and efficiently find the necessary power. After three weeks since this treatment, I am happy to report that all bed bugs have truly been "knocked out" of my condo !

I was very happy with the gentleman who came to the house. So much that I signed the full
year package. I was not happy with the customer service person when I called 5 days later for a respray because I saw some more carpenter ants. He told me that I would have to wait
2 weeks for another application-that didn't happen the last time I used your service.
