Beetles can be moved in yard debris through the removal and movement of items such as sod and grass clippings. The risk of moving beetles is highest over the summer when adult beetles are emerging from the soil and moving around to feed and find mates.
It is very important that beetles are contained within Washington County while treatment takes effect. Containment efforts are ramping up, with a quarantine on all yard debris still in effect and expanding in 2018. Residences will receive electronic notices from Oregon Department of Agriculture, along with other communications planned throughout the summer.
For more information about the quarantine check back on our Prevention page for the most recent information.

Wherever you find Japanese beetles here in the United States, you find extensive damage to plants. Many areas of the United States are infested with Japanese beetle. Above you can see a clear picture of the devastation caused by these infestations that we do not want in the Pacific Northwest.
The issue is that the beetle likes many of the plants that we like to eat and grow in Oregon. The small breeding population of Japanese beetle in Washington County threatens Oregon’s agricultural economy and natural ecosystems. In order to prevent a population explosion of Japanese beetle, Oregon Department of Agriculture proposes to treat the affected areas in the spring of 2018, continuing with annual treatments until 2021 if necessary.
The Oregon Department of Agriculture has been lucky to learn from experts and invasive species managers from around the world who have a long history of combatting Japanese beetle. Find out about the unique proposed plan for treatment in Oregon, here: www.japanesebeetlepdx.info/treatment

After treating the areas of Cedar Mill and Bonny Slope in Washington County this past spring, Oregon Department of Agriculture makes plans for Japanese beetle battle part 2.
A total of just over 23,000 destructive Japanese beetles were caught in Washington County this year. “The threat to Oregon is more imminent now because of the numbers of beetles we are seeing and the fact that we have seen damage to plants within the epicenter of the insect’s population, so it’s not hypothetical, it’s for real,” says ODA’s Burfitt, a veteran of successful Japanese beetle eradication projects in Utah. “However, I’m still optimistic about eradicating our current infestations. As long as the community continues to support the 5-year project, I know we can get this done.” Find out more about the project: Oregon Department of Agriculture will be working with partners and the community throughout the winter and spring to make plans for year two of the proposed eradication project. Read up on year one and what that means for year two: https://wp.me/p52oQB-oP
