Amityville, NY
The technician was professional, courteous,informative and explained everything. Thanks.
Southold, NY
Mike was informative and respectful throughout the appointment.
Nevertheless, the same number of yellow jackets were flying after treatment.
We’re not in Southold now to check for improvement.

We have been a customer since Knock Out took over our contract from the former company CMC.
$380 is excessive considering we are loyal customers. Please accommodate us on this fee.

Business Owner's Reply · 6 days ago (Oct 14)
Good morning,

Thank you for the feedback- We original serviced you for the first time on 10/01/2021 and we told you to give the products at least 14 days to work. You called us after 3 and 8 days and we set up an additional service for the 15th of October.
Our products do not make the problem worse but they do take time to become fully affective.

Thank you.

Roosevelt, NY
Danny i believe his name was,he was very polite, and had proper etiquette. but now as far as treatment i would say it worked about 97% because i still see bees/wasp. about 3 a day but im not sure where they are coming from but they are being affected by the treatment because when i do see them they seem to be stunted and struggling to function. so thats why i gave 4/5. i dont like to be annoying but i just might have to call you guys back again to figure out where the remaining bees are coming from and how they are getting in.

Glen Oaks, NY
We’re pleased with all the people who we dealt with from Knockout Pest Control regarding our ant problem. We waited for 2 weeks and our problem wasn’t gone. We had another technician come here this morning, he used a different solution to stop the ants from invading our house. We surely hope this second treatment will rid us of our ants!
