Interstate Pest Management is a family-owned, environmentally-friendly pest control company proudly serving the twin cities of Centralia and Chehalis, WA, and select areas of Lewis County. We have been exceeding our customers’ expectations since 1963. Our proactive approach to pest control was born out of a commitment to the region we love.

Centralia and Chehalis are twin cities located in western Lewis County, WA, both centrally located between Seattle to the north and Portland to the south. Residents like that the capital city of Olympia is only a short commute away, yet you’re surrounded by forests and farmlands. Though they are referred to as twin cities, each offers its own unique activities and personality.

Chehalis is the Lewis County seat. It began as a logging and railroad town and today the city is home to the Chehalis Centralia Railroad & Museum. The city has several distinct historical areas and has 11 locations on the list of the National Register of Historic Places including Claquato Church, the oldest standing church building in the state of Washington.

Centralia was founded by a different George Washington, a Black pioneer who migrated from the South to the Pacific Northwest in the 1850s. George Washington Park sits in the center of the city. Centralia began as a railroad town, and the city first received its name because it was the midway point between Tacoma and Kalama, WA along the former Northern Pacific Railway (NP). Thanks to the construction of I-5, the name continues to make sense as the city is located minutes off Interstate, between the cities of Portland and Seattle.

Interstate Pest Management serves both cities and the surrounding communities in Lewis County, WA. We are committed to providing green, eco-friendly pest services.
