Japanese Beetle Industry Webinar Recording available
Japanese beetle can impact farmers, growers, nurseries, and landscaping companies. If you work in Yakima, Benton, or Franklin counties you’ll want to prevent the spread of this invasive beetle. You may also need to learn how to follow the newly expanded and amended WAC 16-470 Japanese beetle quarantine. This webinar shared about Japanese beetle trapping, compliance agreements, and treatment consultation if necessary. Learn how you can help eradicate Japanese beetle and watch this webinar.
The Rule
The Japanese beetle quarantine is a rule. The rule prohibits movement of plants, soil, plant waste, and other items out of the quarantine area. This impacts parts of Yakima and Benton counties. Learn more about chapter 16-470 WAC.
Prevent the spread
The invasive pest can be destructive in multiple life stages. As an adult, it feeds on leaves, flowers, and buds of plants. As a young grub, or larvae it lives in the soil and feeds on roots of grasses and other plants. If you move plants and soil you can spread Japanese beetle. They can move in potted plants, soil, yard debris, cut flowers, and other things.
Restrictions
The larvae live in soil, so moving dirt can transport them to new areas where they will emerge as adults. Adults feed on vegetative material, so it is important to leave that on sight, or treat it prior to moving.
See the table below for affected items
ALWAYS PROHIBITED | PROHIBITED MAY 15 - OCT 15 | NEVER PROHIBITED |

There are additional steps you can take to not move beetles
- Self-inspect vehicles for beetles prior to leaving areas where Japanese beetles have been found.
- Tarp or cover trucks or shipments to prevent Japanese beetles from hitchhiking
- Yard waste should be taken to a Yard Debris Drop-Off.
Compliance Agreement
If your operation moves items outside of the quarantine area, you are required to prove items are free of beetles BEFORE movement. Growers should work with WSDA to create operational agreements called compliance agreements.
- Contact WSDA to place and monitor traps from May 15 - October 15 when adult beetles are active. If no beetles are present in WSDA-placed and monitored traps some articles may be moved without treatment.
- Use an approved treatment process prior to movement. Treatment records detailing the application of an approved insecticide may be needed.
To learn more and to create an agreement contact Plant Services by emailing plantservices@agr.wa.gov or calling 360-902-1922 or 360-902-1874.
If your operation is outside of the quarantine area you can still monitor for Japanese beetles. Learn more on our detections and trapping webpage.

CONSULTING
WSDA is working on a multi-year project to eradicate Japanese beetle, but it will take cooperation between growers, industry, and residents.
