Smithtown, NY
Initial service has been very courteous and effective for carpenter ants and other pests. Our technician, Albert, listened to our concerns and treated the indicated areas. We are starting to see some crickets in our downstairs bathroom and may have to call Albert back for a follow-up treatment. However, the communication from Dee, Fred and other office staff is excellent, therefore, I'm confident they'll return if and when it's requested. Thank you!

Mount Sinai, NY
The service was outstanding. Two technicians came for two different services.
The first one for treated our house for all bugs, inside and outside in all the attached structures. It took time but he always explained was he was doing and educated us in detection of primary signs of different insects infestation.
The second technician came, and also did a great job. Explained the type of pest control that was going to be applied. It showed me where this going to be places and how it works.
In addition, was polite, and used all the safety PPE recommended in this days.
Very satisfied with the service.

Seaford, NY
We called on a Sunday during a holiday weekend and during covid. The guy who came on Monday with the k9 pest dog was very knowledge and told/showed us what to look for and two days later, Sav and his partner came, they were friendly and explained what was going to happen. We left for a little and when we came back they talked to us about life and everything going on with the virus. And then left after being at our house almost all day. Before they left, they showed us the rooms and explained it was going to be hot for a little and what to do and if any problems after to let them know. Honestly the house looks the same as before they came. I would defi. use this company again and I would even ask for Sav personally. Thanks again amazing service and no bugs problems since then!

Brooklyn, NY
I've used Knockout Pest Control before so I thought I would use them again. Keep in mind, we are "shelter in home" due to Covid but they were very easy to reach and Mark (who answered the call) was extremely helpful answering my questions about the service. I received a quote and when I said I had a coupon, he said they would honor it no questions asked. I was able to get an appointment easily and I got a call 5 minutes before Andre was scheduled to arrive. Andre was very good about respecting my "no shoes inside" rule and put on/took off shoe covers so that no dirt would be tracked in my home. He was also very helpful in answering my questions. I would definitely use them again. Excellent customer service!
