Wherever you find Japanese beetles here in the United States, you find extensive damage to plants. Many areas of the United States are infested with Japanese beetle. Above you can see a clear picture of the devastation caused by these infestations that we do not want in the Pacific Northwest.
The issue is that the beetle likes many of the plants that we like to eat and grow in Oregon. The small breeding population of Japanese beetle in Washington County threatens Oregon’s agricultural economy and natural ecosystems. In order to prevent a population explosion of Japanese beetle, Oregon Department of Agriculture proposes to treat the affected areas in the spring of 2018, continuing with annual treatments until 2021 if necessary.
The Oregon Department of Agriculture has been lucky to learn from experts and invasive species managers from around the world who have a long history of combatting Japanese beetle. Find out about the unique proposed plan for treatment in Oregon, here: www.japanesebeetlepdx.info/treatment
