Keystone Pest Control was formed in 1992 by John Pirrone and Steve Dietrich after working for other pest control companies for many years. Our philosophy was to form a company that would give personalized, effective service to both homes and businesses. Having worked in the Bay Area in pest control for many years, we felt we had a lot to offer our customers in experience and quality.In spite of growing our business over the last twenty years, we still believe in being hands-on in every aspect of our business, managing day-to-day operations and assuring customer satisfaction is always our first priority. Being an independent small company allows us to utilize all new innovations in our industry as they become available. It also allows us to continue to provide the friendly, personal service we are known for.
All of our technicians are licensed by the State of California Structural Pest Control Board and fulfill all continuing education requirements to maintain their licenses. Ongoing in-house education assures our customers receive the best service possible. Our technicians are also required to pass a Department of Justice Live Scan background check and are committed to providing the best pest control service for our customers before being hired.
