The service is excellent!!! The exterminator was very knowledgeable and professional

I had a sudden attack of ants - it was like overnight they were everywhere. I tried boric acid and baits, but nothing worked. After one visit from Knockout I saw one ant and absolutely nothing ever again. It was almost like magic

I HIGHLY recommend them !!!

Astoria, NY
After two days there seems to be no signs of bugs. I was very pleased with the customer service I received throughout this experience. The technician was very informative and so was the customer service representative. I would recommend any one with bed bugs to use knockout.
Excellent customer service over the phone by Dee answering all my questions. Great service by tech Christian on day of treatment.
The phone staff - Dee in particular was very helpful and patient. The technician,Christian, was extremely professional. He answered all our questions. We felt very comfortable leaving our home in his hands. We are hopeful that this treatment will solve the problem.
Knockout pest control provided the traps and poisons to kill the mice that are in my apartment. Unfortunately I have not been able to locate the sight of entry for the mice, so they remain a problem! So far one baby mouse has been caught!
Easy to schedule with. Ant problem improving but not 100% yet - but was told could take 2-3 weeks.
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.
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 :-)

Great experience knowledgeable and courteous will definitely recommend.
He was knowledgeable and professional. Good job! Thanks.
Professional and explained what he was doing. Gave us the paperwork associated with the pesticides used.
Extremely satisfied. The technician arrived on schedule and very efficiently took care of my problem.
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.
Junior was very pleasant - came on time - took care of the problem and explained the process..
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.
From the young lady on the phone to the gentlemen that turned up at the door, these people are polite respectful & ever so efficient. I wish there was ten stars. They deserve it.
Edwin was fantastic. Very happy I chose Knockout.
The technician was very courteous and knowledgeable and patient to do the job right.
Unfortunately, we have had to use your service twice, once for termite and now fleas. Fortunately, both experiences accomplished the goal of eliminating the pests. Thanks again.
Extremely professional and helpful. I needed service prior to the schedule appointment and they came right away.
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.
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.
