Emerald Ash Borer Found in Kandiyohi County; emergency quarantine in place

The Minnesota Department of Agriculture (MDA) has confirmed the presence of emerald ash borer (EAB) in Kandiyohi County for the first time. There are now 35 counties in the state, including Kandiyohi, with EAB.

A tree care company contacted the MDA after suspecting a tree on the west side of Nest Lake near Spicer was infested with EAB. MDA staff were able to find live 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 Kandiyohi County, the MDA is enacting an emergency quarantine which limits the movement of firewood and ash material out of the area. The emergency quarantine will cover the northeast corner of the county, from U.S. highways 71 and 12 on the western and southern borders, respectively, and the county line on the northern and eastern borders.

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 Kandiyohi County will be held on Wednesday, June 8, 2022. Experts from the MDA will give a brief presentation followed by a question-and-answer session.

The public will also have an opportunity to provide input on the proposal to add the partial Kandiyohi County emergency quarantine to the state’s formal quarantine. The MDA is taking comments on the proposed formal quarantine now through July 8, 2022, and recommends adopting the quarantine on July 12, 2022. The proposed quarantine language can be found at www.mda.state.mn.us/eab.
