About Pest Stop

More Than Pest Control — It’s Peace of Mind.

At Pest Stop, we believe pest control is about far more than eliminating insects and rodents. It’s about protecting the health, comfort, and peace of mind of every family, pet, and community we serve. That belief has guided us through more than five decades of service in Western Washington — and it’s more central to who we are today than ever before.

Ours is a story of family, science, and an unwavering commitment to doing things right.

A Family Legacy — Rooted in 1956

The story of Pest Stop begins not in Olympia, but in Memphis, Tennessee, in 1956 — when Chuck Sullivan’s great uncle Joe began his career with Bruce Terminix. Pest control was in the family’s blood from the start.

By 1960, Chuck’s father Quitman had joined his uncle in California, quickly rising through the ranks to manage the San Jose office by 1964. Pest control wasn’t just a job in the Sullivan household — it was dinner table conversation, a family trade, and a source of deep professional pride.

Chuck Sullivan grew up immersed in that world. By the age of 17, he was working alongside his father — becoming one of the youngest certified pest control operators in California. Over the years, Chuck worked his way from route technician to managing Terminix in Tacoma, and ultimately to founding his own company: Chuck Sullivan Exterminators.

In 2000, Chuck and his wife Karla renamed the company Pest Stop — a name that better reflected their vision for the future and their growing presence across Western Washington. What followed were decades of trusted service, thousands of satisfied customers, and a reputation built on integrity, reliability, and genuine care for the communities they called home.

Chuck and Karla didn’t just build a business. They built something worth passing on.

A New Generation — The Same Commitment, Elevated

In 2025, Chuck and Karla proudly passed the torch to their son, Billy Olesen, who now leads Pest Stop as President and Owner. Billy didn’t simply inherit a company — he grew up inside one, learning the trade from the ground up before carving out a distinguished path of his own. Billy’s career mirrors his family’s tradition of starting at the roots. He has served as a Route Manager at Mathis Exterminators and as a Training Manager at Sunrise Pest Management — roles that gave him firsthand understanding of field service, technician development, and the customer experience that defines a great pest control company. He knows what it means to be the person at the door, doing the work, earning the trust. 

But Billy brought something new to the family legacy: science.

Led by an Entomologist — Backed by Science

Billy Olesen is an Associate Certified Entomologist — a credential that sets Pest Stop apart from virtually every other local pest control company in the Pacific Northwest. Where others see bugs, Billy sees biology. Where others apply products, Billy applies knowledge.

In 2022, Billy was honored with the Entomological Society of America’s ACE Professionalism Award — one of the most respected recognitions in the entomology field. It reflects not just technical expertise, but the professional character and ethical standards that define how Billy approaches every aspect of this business.
Under Billy’s leadership, Pest Stop operates on the principles of Integrated Pest Management (IPM) — a science-based approach that prioritizes targeted, justified treatments over blanket applications. Every service recommendation is grounded in pest biology, treatment thresholds, and the least impactful effective solution. This isn’t just policy. It’s how Billy was trained to think, and it’s the standard he holds his entire team to.

At Pest Stop, our technicians are educators first, applicators second. We explain the problem, the plan, and the expected outcome — clearly and honestly — every time.

Shaping the Industry — Not Just Serving It

Billy’s influence extends well beyond Pest Stop’s service area. As the State Policy Affairs Representative (SPAR) for the Washington State Pest Management Association (WSPMA), he serves as a direct bridge between the pest control industry and state government — advocating for responsible, science-based pesticide policy on behalf of professionals and communities across Washington.

He is also a member of the Washington Commission on Integrated Pest Management and the Washington State Pollinator Health Task Force — two bodies that shape how pest control intersects with environmental stewardship, agriculture, and public health at the state level. Additionally, Billy serves on the Board of Washington Friends of Farms and Forest, and previously chaired the Kitsap County Noxious Weed Control Board.

When you hire Pest Stop, you’re not just hiring a local pest company. You’re hiring a team led by someone who is actively helping define what responsible pest management looks like across the entire state.
 

Safe for Your Family — Every Member of It

We understand that your home isn’t just where you live — it’s where your family lives. And for most of our customers, that family includes pets. At Pest Stop, the safety of children, animals, and sensitive individuals is never an afterthought. It’s built into every treatment decision we make.

We also care deeply about the broader environment we work in. Billy’s involvement with the Pollinator Health Task Force reflects a genuine commitment to protecting bees, beneficial insects, and non-target organisms — not just meeting compliance minimums, but doing right by the ecosystems that sustain our communities.

In the Pacific Northwest, we don’t take that responsibility lightly. And neither does Pest Stop.

Community Is Why We Do This

Pest control, at its core, is a public health service. Pests spread disease, damage homes, and disrupt quality of life. Doing this work well — responsibly, scientifically, and with genuine care — matters to the health of the communities we serve.

From Olympia to Portland, Pest Stop has been protecting Western Washington and Oregon homes and businesses for over five decades. We are proud recipients of the Best of the South Sound award — a recognition voted on by the very neighbors and customers we serve every day.

We are grateful for every customer who has trusted us into their home. That trust is not something we take for granted — it’s something we earn, every single visit.

More Than Pest Control — It’s Peace of Mind.
