The Oregon Department of Agriculture will begin the fourth year of treatment against Japanese beetle in April of 2020.
Areas with lawns and ornamental planting beds within the treatment boundary are scheduled to receive up to two treatments for Japanese beetle control in April, May, June, or July 2020. Treatment consists of one treatment of a granular larvicide applied to all grass lawns and/or ornamental planting beds in areas where beetles were detected in 2019. In areas with high beetle densities a second supplementary foliar application is scheduled. For more information: visit the Japanese Beetle Project website.
Thank you for your continued support and cooperation to keep this invasive pest out of Oregon.
