Survey and Treatment Projects

​​​​​Japanese beetle eradication project

The Oregon Department of Agriculture will begin the sixth year of treatment against Japanese beetle in April of 2022.

Areas with lawns and ornamen​tal planting beds within the treatment boundary are scheduled to receive up to two treatments for Japanese beetle control in April, May, June, or July 2022. 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 2021. In areas with high beetle densities a second supplementary foliar application is scheduled.​
