Knockout responded quickly to my call and had a technician at my house at a time that was convenient for me. The technician called to let me know when he would be arriving and described each step of what he would do to manage the pest problem. I regularly recommend Knockout Pest Control.

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!
