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.
