PLEASE NOTE: THIS POST IS AN ARCHIVE FROM 2017. People should expect to see an abundance of Japanese beetles in the quarantine area this summer. As adult beetles begin to emerge from the turf, you can see them feeding on the leaves of a variety of garden and landscape plants. In the weeks to come, adult beetles will lay eggs in areas treated by Oregon Department of Agriculture (ODA). Grubs that hatch deep into treated turf will ingest the granular insecticide Acelepryn applied over the 1,000-acre area and not survive to complete another generational cycle. It is anticipated that subsequent annual treatments will become smaller until the entire population of Japanese beetle in the area is eradicated.
If you see the adult Japanese beetle within the treatment area then the Oregon Department of Agriculture advises that you dispose of them in a container of soapy water. If beetles are observed outside the treatment area please put the specimen in a container or bag and email or call ODA at the contact information provided below.
