Interstate Pest Management is a family-owned, environmentally-friendly pest control company proudly serving communities throughout Cowlitz County, WA including the city of Castle Rock. We have been exceeding our customers’ expectations since 1963, and our proactive approach to pest control was born out of a commitment to the region we love.

The city of Castle Rock, WA is named for a 190-foot-high volcanic rock on the south side of the city resembling a castle. It was a geographic landmark for both the Cowlitz Indians and Hudson’s Bay Company traders, and today it’s the location of The Rock Community Park. The park includes a historical marker, hiking trails, and picnic tables.

The Mount St. Helens Visitor Center is located in Castle Rock and is connected to the city by the Spirit Lake Memorial Highway aka State Route 504. You can also take this route to the Spirit Lake recreation area, Seaquest State Park, and Silver Lake. Castle Rock is the closest city to the Mount St. Helens National Volcanic Monument, a U.S. National Monument that includes the area around the volcano.
