ST. PAUL — The Minnesota Department of Agriculture (MDA) has identified an emerald ash borer (EAB) infestation in Chisago County along the Washington County border near Manning Trail.

Two EAB adults were found on a purple EAB survey trap, and a follow-up visit discovered tunneling consistent with invasive pest in a nearby tree.

Because this is the first time that EAB has been identified in Chisago County, specimens have also been sent to USDA for confirmation.

Pending confirmation, the MDA and USDA will work closely to determine appropriate follow-up actions.

Chisago County will likely be put under an emergency quarantine in the next week and eventually join Anoka, Dakota, Fillmore, Hennepin, Houston, Olmsted, Ramsey and Winona counties in a state and federal quarantine.

The invasive insect was first discovered in Minnesota in 2009. The last county to be quarantined for EAB was Fillmore in April 2015.

There are three easy steps Minnesotans can take to keep EAB from spreading:

•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.
