On July 11, 2022, APHIS confirmed the identification of emerald ash borer in Washington County, Oregon. The Oregon Department of Agriculture believes that the infestation has been in Washington County at least 3-5 years. Regulatory efforts to stop the spread of emerald ash borer were not effective and it has spread through much of the United States. Emerald ash borer is now in 36 States and the District of Columbia.
APHIS encourages the public to be on the lookout and report emerald ash borer, and has outreach materials including videos, photos, factsheets, and online reporting available. You can also sign up to receive the emerald ash borer program report through our Stakeholder Registry [PDF, 135 KB].
