A neighbor has a large, dedicated garden area with three raised beds, plus a flat area for other options/plants, etc. in the Cedar Mill area. She has no plans to use it and wonders if there are neighbors that would love to have a garden but don’t have space. She says, “I would require them to keep it managed at all times. The entrance is locked because I have a dog. I will not give anyone the key, but will always be here for when they want to come in.”

Japanese beetle eradication project

The Oregon Department of Agriculture began the seventh year of treatment against Japanese beetle in April of 2023. Areas with lawns and ornamental planting beds within the treatment boundary were scheduled to receive up to two treatments for ​Japanese beetle control in April, May, June, or July 2023. 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 2022. In areas with high beetle densities a second supplementary foliar application is scheduled. For more information: visit the Japanese Beetle Project website.​

Yard debris quarantine​

Due to budget constraints the Oregon Department of Agriculture (ODA) cannot offer free yard debris collection and disposal services for residents living in the Japanese beetle yard quarantine. So instead, ODA is prioritizing pesticide application and trapping in infested areas. In addition, to help monitor any possible spread, ODA will increase the number of traps placed for detecting Japanese beetle in areas where yard debris waste is brought for disposal.

Lawmakers will allocate agency budgets for the next biennium (2023-2025) by the end of June. At that time, ODA will reassess costs and the ability to pay for yard debris collection and waste management in 2024 and beyond.

Thank you to those who have supported the quarantine over the past six years. ODA asks for the public’s continued support. The best way to help limit the spread of Japanese beetle currently is to ensure you are not moving any plant material, including outdoor potted plants, to new locations outside of Washington County. Also, please refrain from participating in any plant swaps if you are within the treatment area. To see if you are within the treatment area please visit (The area has changed somewhat because some previous traps collected no beetles!) Residents in Washington County can continue to use their curbside yard debris bins as usual.

For more information on where to take your yard debris material (for those within a treatment area), please consult this list of participating disposal sites: Yard Debris Waste Disposal Sites in Washington County
