Emerald Ash Borer Found in McLeod County

Emergency quarantine on wood movement put in place for McLeod County

St. Paul, MN: The Minnesota Department of Agriculture (MDA) has confirmed the presence of emerald ash borer (EAB) in McLeod County for the first time. There are now 42 counties in the state, including McLeod, with EAB.

An MDA employee noticed ash trees several miles east of Hutchinson with suspected signs of EAB. The employee was able to find EAB larvae and collect samples. Federal identification confirmed emerald ash borer.

EAB was first discovered in Minnesota in 2009. The insect larvae kill ash trees by tunneling under the bark and feeding on the part of the tree that moves nutrients up and down the trunk. Often, the trees show several signs of infestation because of this. Woodpeckers like to feed on EAB larvae, and woodpecker holes may indicate the presence of emerald ash borer. Also, EAB tunneling can cause the bark to split open, revealing characteristic S-shaped galleries underneath.

Because this is the first time EAB has been identified in McLeod County, the MDA is enacting an emergency quarantine of the county, which limits the movement of firewood and ash material out of the area.

The MDA issues quarantines for all areas known to have EAB to reduce the risk of further spreading the tree-killing insect.

A virtual informational meeting for residents and tree care professionals in McLeod County will be held on September 12, 2023, from 10 a.m. ? 11 a.m. Experts from the MDA will give a brief presentation followed by a question-and-answer session.
