Meet The Owner
STL Pest Control is proudly led by Rick Isenmann and his son, Zach Isenmann — a family-operated business built on hard work, integrity, and a genuine commitment to taking care of people.
Rick Isenmann founded STL Pest Control in the metro St. Louis area in 1989 after investing his own savings to start a small pest control company out of his home. From the very beginning, Rick focused on doing things the right way — providing honest service, dependable results, and treating every customer like family. Over time, his dedication and reputation for quality work led to a strong base of loyal customers who regularly referred his services to friends and family.
While growing STL Pest Control, Rick also maintained a full-time career in the offset printing industry for more than 29 years. During that time, he balanced two careers while raising three children with his wife, Nancy. As the pest control business continued to grow, it became clear that Rick’s true passion was serving customers in the pest control industry, and he made the decision to move into the business full-time.
Rick enjoys working directly with customers on a daily basis. Whether it’s inspecting attics, treating crawl spaces, or providing routine pest and termite control, he believes in putting the customer first. His philosophy has always been simple: work hard, do right by people, and the rest will fall into place.
To support that mission, Rick carefully handpicked some of the best professionals in the pest control field to build a first-class organization. Today, STL Pest Control has a full office staff dedicated to answering questions and scheduling appointments, along with 14 full-time service technicians. We proudly service all pest control needs — from wildlife control and termites to everything in between.
Family has always played an important role in the company’s foundation. Rick’s father, Bob, was instrumental in shaping STL Pest Control during its early years. Bob brought a wealth of knowledge to the business, but more importantly, he emphasized the importance of taking care of the customer. He was also Rick’s first full-time termite technician, working side by side with him and enjoying every opportunity to serve customers together. Even at 85 years old, Bob was known for rolling up his sleeves and getting the job done. Although he is deeply missed, his dedication and customer-first mindset continue to guide how the company operates today.
In 2020, Rick’s son Zach Isenmann joined the organization to help carry on the family tradition of doing pest control the right way and helping people. Zach now serves as General Manager, overseeing the day-to-day operations of the company and ensuring that every customer receives the same level of care, professionalism, and attention that the business was built on.
Both Rick and Zach serve on the Board of Directors of the Greater St. Louis Pest Control Association, with Rick currently serving as President. Through their involvement, they help set higher standards for the industry, support continuing education for pest control professionals, and actively participate in fundraising efforts for disabled veterans and other community causes.
Thanks to decades of hard work, long hours, and a dedicated team, STL Pest Control has grown into a trusted and successful company. We continue to set new standards in the pest control industry by focusing on exceptional customer service while maintaining fair and affordable pricing.
