To all first-time site visitors: welcome! And thank you for reading more about this important project to protect Oregon’s agricultural economy and natural resources.
Here is a quick update on decisions made in the last few months
In the summer of 2018, Oregon Department of Agriculture (ODA)’s traps caught over 17,000 Japanese beetles. Treatments in 2017 reduced the 2018 Japanese beetle populations by approximately 34%. In response, this past winter the Japanese beetle project team has been busy analyzing the detections and meeting with partners to create a strategy for 2019. The beetle battle is in high gear! Based on the information collected, the project is moving in the right direction with a lot of work ahead. A third year of treatment is proposed for 2019 with an expanded boundary to treat new areas where beetles have been found. The treatment will happen in March, April, and May using the same larvicide, Acelepryn G. Acelepryn G will be broadcast in the form of small granules over irrigated turf grass and ornamental beds of all properties in the designated treatment area in Washington County. In areas where the largest concentration of beetles were found last year, ODA may need to do a smaller targeted application of Acelepryn later in the summer to increase effectiveness of the treatment. Note: if you are in the area identified as needing an additional treatment, you will receive official notice by mail.
How to help
This is the state’s largest Japanese beetle eradication effort. There are multiple ways that you can help.

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.
