Survey and Treatment Projects

Japanese beetle eradication project

The Oregon Department of Agriculture is in the third year of treatment to battle the Japanese beetle—the 2019 project started in April. 

Acelepryn G, a granular larvicide, is the same product that has been used for all three years of the project. 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

To comply with the quarantine to prevent the spread of both Japanese beetle adults and larvae, all residents, landscapers, and waste managers that work in the yard debris quarantine area must follow the steps below. 

  • Residential yard debris including grass clippings, plants with soil, and sod must be contained and delivered to Northwest Landscape Services (details below). 
  • Compost and transfer facilities ARE NOT ALLOWED to accept yard debris from the quarantine area in order to prevent the spread of Japanese beetle. 
  • If possible, keep yard debris at the property or use a standard curbside yard debris bin.
  • If yard debris must be removed from the property, bag and cover the load and take it directly to Northwest Landscape Services.
