Ardsley, NY
Easy to schedule with. Ant problem improving but not 100% yet - but was told could take 2-3 weeks.
Brooklyn, NY
I called 5 exterminators and Knockout stood as out as thorough and clear on the phone. They provided the most information, and were calming and supportive. Everyone I spoke with on the phone, as well as the 2 professionals who came to the house, left me feeling completely competent with their services. I fully recommend them and would use them again.
Middle Village, NY
From the outset of our disasterous situation, Erin was readily available to guide us through the infestation remediation process. In addition to being knowledgeable on the subject, she was kind, caring and professional.
Sav, our technician was equally knowledgeable and comforting. He keep me informed with timely and accurate updated throughout the procedure.
Start to finish, infestation was discovered on a Thursday night and totally gone (hopefully) by Tuesday night.
The quality of service rendered by the staff at Knockout Pest is definitely commendable. At no point during this process did I feel like I was being taken advantage of due to the unfortunate issue of having a bed bug infestation in one's home.
Many thanks to all :-)

Oceanside, NY
I am extremely pleased with the service that I was provided. Our technician, Edwin, was knowledgeable, professional, friendly, and best of all did an amazing job. He told us what needed to be done and accomplished all of the necessary steps to ensure that we would not have any unpleasant visitors (pests). In addition, his advice was so valuable that we decided to sign up for the KO-12 in order to continue to get this high quality protection. I am making sure that in the future we request to have Edwin because a great work ethic like his is hard to come by. Best of all, it was a wonderful surprise to see him place on his shoes, booties when he was in my house. It is nice to see that there are still people in this world that care and respect the property of others. How often do we see workers come into your house and in fixing one thing cause damage to other areas. I prefer not to take two steps back for every step forward. I look forward to having Knockout continue to protect my house from termites as well as other unwanted critters.

Excellent! Christian (not Garfield) was my technician. He knew what he was doing and got right to work. He explained everything to me, made suggestions to me, and listened to what i said. We have a cat and he was very careful when he opened the door.

Extremely professional and helpful. I needed service prior to the schedule appointment and they came right away.
Oceanside, NY
I was very happy with my service. Edwin came and listened to me, and was able to explain what he was going to do in a clear manner. He was very polite, and thorough. I was seeing ants everyday before knockout, and now it's been almost 5 days, and not one ant in sight. I bought a year contract, so I hope the future appointments go well too.
Brooklyn, NY
Knockout were very good at helping us sort our our problem. The technician worked from 7 am until 6.30 pm to treat our home. Great service. Thank you.
Holtsville, NY
I had a contract with Knockout since I moved into this house 31 years ago. Not sure when it was transferred over to the new owners.. I kept up the yearly payments.. the one time I called them they said I was not covered and had to pay $364 to help solve a problem I should have been covered for. They gave me a discounted price but should have told me in advance that I was not covered. Was very unhappy about it.
East Atlantic Beach, NY
Edwin was fantastic - he did a great job and I would request Edwin again - he was great- thank you sending Edwin to do the work- Tom Burke.

Oceanside, NY
Have always been happy with Knockout, was customer for 17 years in prior home. Came to our new home today. George is the absolute best, very thorough, and a sweetheart! A pleasure!
Bedford, NY
Did not show up during the time window scheduled. Technician called and left message way after the scheduled time to let us know he is late. The customer service agent blamed me (I) for not being there to answer the call when it was past the scheduled time and I had to leave for work and (I) for not calling to inquire why the technician was late. For this reason we are not using this firm anymore.
Business Owner's Reply · 2 months ago (Jun 29)
I am sorry we did not live up to your standards. We had an appointment between 8 and 11. Our technician was delayed by traffic tied up with an accident. We did call to say we were running late and got to your home just after 11.

We do our best to accommodate our clients and when we fall short, as we did today, we all feel disappointed. This is not the normal for us.
Roosevelt, NY
Technician was good seemed knowledgeable. Left a million traps inside the house.

Terrence was a very nice gentleman. I have a toddler in the house and my wife is expecting, so he politely informed us that it's better if they weren't in the house while he was spraying. Very considerate.
