Loads of fall leaves DO NOT need to be taken to the Japanese beetle yard debris drop off site in Hillsboro. Loads of fallen leaves are not a risk to spread Japanese beetle and are not part of the quarantined material. Please see the list below for material that falls within the quarantine.
The yard debris quarantine is intended to prevent the spread of Japanese beetle in Oregon and to ensure the success of the current eradication program. The quarantine went into effect in Summer of 2017 and is still active through 2018. The boundary of the quarantine was expanded because of increased Japanese beetle detections in the county in 2017.
The Oregon Department of Agriculture is asking all residents, landscapers, and waste managers that work in the yard debris quarantine area to adhere to the information below in order to comply with the quarantine to prevent the spread of both Japanese beetle adults and larvae:

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.

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
