Interstate Pest Management is a family-owned, environmentally-friendly pest control company proudly serving the city of Rainier, OR, and the rest of Columbia County. 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.

Right across the Columbia River from our Kelso, WA headquarters is the city of Rainier, OR. Rainier gets its name from Mount Rainier in Washington State which can be seen from hills above the city. It’s one of seven cities located in Columbia County, OR and is part of the Port of Columbia County, a district spanning 51 miles along the Columbia River.

Rainier City Park sits on the riverfront and provides a great view with river beach access, a playground, sports fields, and a skate park. Trojan Park is a 75-acre park located just south of Rainier on the property at the former Trojan Nuclear Power Plant. It’s a day-use park with facilities for biking, disc golf, fishing, hiking, paddling and picnicking.

Interstate Pest Management’s Kelso branch services the city of Rainier with integrated pest management solutions to help keep your home and property pest free!
