Seasonal pest survey sees increase in Japanese beetles
WSDA trappers caught 72,626 Japanese beetles (Popillia japonica) this year, a nearly threefold increase in the number of beetles trapped over 2024 catches, with the majority of beetles trapped in the Grandview area. The areas where the beetles have been detected also expanded slightly. Learn more in the latest press release.
Free yard waste drop-off ends October 31.
Beginning November 1, the free yard-waste drop-off ends for the year. Soil-free yard waste can move out of the quarantine area from October 15 - May 15. Local waste facilities may accept yard waste, but it will be at the expense of the resident.

Japanese beetle (Popillia japonica) is a destructive, invasive insect that feeds on over 300 plants. Adults skeletonize leaves and damage buds, flowers, and fruit. Grubs (larvae) are found in the soil and eat grass and other roots. It is a serious pest for both residents and the agriculture industry in the Eastern U.S. where it is established.
If Japanese beetle were to establish in Washington, it would pose a serious threat to gardens, parks, and farms. Quarantines can start which make it difficult and expensive to move agricultural and nursery products. Together, WSDA, community members, landowners, and growers can protect Washington and support the ongoing eradication project.
