From the Clark website “About Us“:
The History of Clark Pest Control
Founded shortly after World War II by returning veterans, Clark Pest Control has since grown to become the West’s largest pest management company with branch offices throughout California and in the Reno, Nevada area. Clark Pest Control currently is one of the largest family-owned and operated pest management companies in the United States. We need you!

Our mission
is to exceed client expectations with the most effective pest control available, which is always done in an ethical, professional, responsive and caring manner.
I would definitely not describe the Clark Pest Control collection methods as “ethical, professional, responsive and caring”.
