EAB found in Chisago County

Jeffrey Hahn, Extension Entomologist

The Minnesota Department of Agriculture (MDA) announced on Thursday, August 6 that emerald ash borer (EAB) was confirmed in Chisago County by the Washington County border near Manning Trail. Two adults were discovered on a purple EAB trap. When a follow up visit was conducted, an ash tree with tunneling consistent with EAB was found adjacent to the trap.

The specimens were sent to the USDA for confirmation (standard procedure when EAB is found in a county for the first time). Assuming the beetles are verified as EAB, Chisago County is likely to be put under quarantine sometime next week. A quarantine helps prevent EAB from spreading outside of a known infested area. It is designed to limit the movement of any items, including ash trees and ash tree limbs, as well as all hardwood firewood, to help reduce the spread of EAB

Chisago County becomes the ninth county in Minnesota to confirm EAB, joining Anoka, Dakota, Fillmore, Hennepin, Olmstead, Ramsey, and Winona counties. For more information about EAB, see Emerald ash borer in Minnesota. See also the MDA news release, MDA identifies emerald ash borer find in Chisago County.
