The Minnesota Department of Agriculture (MDA) last Friday identified emerald ash borer (EAB) in the city of Duluth (St. Louis County). Finding EAB in Duluth is not a surprise as Superior, Wisconsin, just across the state border from Duluth, confirmed EAB in August, 2013.
MDA staff found EAB larvae in an ash trees on Park Point. The find was discovered as part of a three-year

Because this is the first time that EAB has been identified in St. Louis County, the specimen have been sent to the United States Department of Agriculture (USDA) for confirmation, which is expected within days.
MDA will be implementing an emergency state quarantine of Park Point in Duluth. A quarantine is designed to help prevent EAB from spreading outside of a known infested area by limiting the movement of any items that may harbor EAB, including ash trees and ash tree limbs, as well as all hardwood firewood.
St. Louis County becomes the 12th county in Minnesota to verify EAB. EAB was also confirmed in 2015 for the first time in Scott, Chisago, Fillmore, Anoka, and Washington Counties. This invasive beetle has also been found in Hennepin, Houston, Olmstead, Ramsey, and Winona counties. These counties are all under quarantine.
The biggest risk of spreading EAB comes from people unknowingly moving firewood or other ash products harboring larvae. Take these steps to minimize spreading EAB:
- Don’t transport firewood. Buy firewood locally from approved vendors, and burn it where you buy it.
- Be aware of the quarantine restrictions. If you live in a quarantined county, be aware of the restrictions on movement of products such as ash trees, wood chips, and firewood.
- Watch your ash trees for infestation. If you think your ash tree is infested, go to www.mda.state.mn.us/eab and use the “Do I Have Emerald Ash Borer?” guide.
