Four Generations of Service & Quality

The only reason you would be reading this page is if a) you're considering applying for a job here or b) you're like us - too curious for your own good. In either case, we're glad and welcome you to our story.

The USA Today version is that we've been solving pest problems for just over 90 years. We got started in the '20s and while there's been some rough patches, we've been growing ever since. Pests don't care if there's a recession, war or regulatory changes. They persist and our team has been protecting the health and property of our community all along the way.

We're proud to tell you we're a rarely seen, fourth generation, family-owned business. Strong values, commitment and a work-hard ethic that doesn't quit? Yes, that is us without a doubt. Stodgy, old school and stuck in our ways? That's not us. Not even close.

Here's the official backstory - well, highlight reel - on Sprague Pest Solutions and how we grew from Mr. Sprague, to Bob and Bernie Treleven's kitchen to today, where we serve businesses throughout our great country.

A Legacy

W.B. Sprague established this pest control company in 1926. The company provided pest services throughout the greater Pierce County, WA area.

In 1931, we were purchased by A. H. Treleven, Sr. and incorporated in the great State of Washington. The economic conditions were poor as the nation struggled through the Great Depression. Sprague was able to survive during this period because the services we provided were essential to our community and the businesses that depended on us.

A.H. Treleven, Jr. joined the business in 1937. He eventually purchased his father's interest in the company. Today, sons Lawrence and Alfred H. Treleven III have taken over the operation and ownership of the company. Cousins Ross Treleven, Larry's son, and A.J. Treleven, Alfie's son, now serve in leadership positions within the company. Larry's daughter, Angela Treleven, serves on the board of directors.


Over the years, many people have joined the Sprague Pest Solutions team. Each person contributed ideas and added perspective to the company, strengthening our foundation. We continue to grow through the abilities of those who work at Sprague.

Our company now provides pest solutions throughout the Pacific Northwest and Mountain regions from multiple offices in Washington, Oregon, Idaho, Utah and Colorado. As a partner in Copesan, our services and clientbase also extend throughout North America. Sprague's success stems from a deep commitment to service and an all-in attitude when it comes to solving problems for others. As we enter new markets, our focus will continue to emphasize quality, personal attention to clients and exceptionally skilled employees.

The tradition established by those who founded this company will also endure. Respect for clients, fellow employees and unwavering dedication to delivering quality pest solutions will carry us through the years ahead.

We invite you to visit, ask questions and become of part of the Sprague family. This is, after all, a pretty special place.
