Started in 1979, Cascade quickly became known for the efficiency, quality and dependability of its pest control service. It’s founders, Kurt Treftz and Diana Sheridan, both native to the Pacific Northwest, have always held a high value for Washington’s abundant natural environment, the welfare of its people and the healthy lifestyle available to us. As a result Cascade Pest Control pioneered various approaches to solving pest control needs, particularly in providing Green Pest Control. Cascade has grown in both stature and experience, developing pest control programs for both residential and commercial environments.
