Japanese Beetle
Japanese beetles (Popillia japonica) are highly invasive pests of more than 300 plants, including roses, grapes, and hops. The adults feed on leaves, buds, flowers, and fruit of plants. Their larvae are found in soil. They can be moved in field or yard waste, purchased plants, infested turf/sod, gardening soil, and more.
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.
The Japanese beetle eradicaiton program is a multiyear project. Together, WSDA, community members, landowners, and growers can win the fight against this invasive pest.
