Survey and Treatment Projects

​​​​​​​​​​​Japanese beetle eradication project

The Oregon Department of Agriculture will begin the seventh year of treatment against Japanese beetle in April of 2024.

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 2024. 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 2023. 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.  

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.

Thank you to those who supported the quarantine from 2017 to 2022. 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 oda.direct/jbmap. 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 

Cuarentena de desechos de jardín

Debido a las limitaciones presupuestarias, el Departamento de Agricultura de Oregon (ODA, por sus siglas en inglés) no puede ofrecer servicios gratuitos de recolección y eliminación de desechos de jardín a los residentes que viven en la zona de cuarentena del escarabajo japonés. Por ello, el ODA está priorizando la aplicación de pesticidas y la captura en las zonas infestadas. Además, para ayudar a controlar cualquier posible propagación, el ODA aumentará el número de trampas colocadas para la detección del escarabajo japonés en las zonas donde se lleven desechos de jardín para su eliminación.

Gracias a quienes apoyaron la cuarentena del 2017 al 2022. El ODA pide el apoyo continuo del público. La mejor manera de ayudar a limitar la propagación del escarabajo japonés en la actualidad es asegurarse de que no está trasladando ningún material vegetal, incluyendo plantas de exterior en macetas, a nuevos lugares fuera del condado de Washington. Asimismo, le rogamos abstenerse de participar en intercambios de plantas si se encuentra en la zona de tratamiento. Para saber si se encuentra en la zona de tratamiento, visite oda.direct/jbmap. Los residentes del condado de Washington pueden seguir utilizando sus contenedores de residuos de jardín en la acera como de costumbre.

Para obtener más información sobre dónde llevar los desechos de jardín (en el caso de las zonas de tratamiento), por favor consulte esta lista de vertederos participantes: ​Vertederos de desechos de jardín en el condado de Washington
