Emerald Ash Borer Discovered in Hugo, MN

The Minnesota Department of Agriculture (MDA) has alerted the City of Hugo after emerald ash borer (EAB) was found in an ash tree located inside the City limits.

The MDA was contacted by a Hugo resident after the tree was cut down and EAB larvae were observed.

Although less than 11% of the trees in the City of Hugo are ash, the City is asking residents to educate themselves about EAB and help slow its spread.

“There are several things residents should look for when checking for emerald ash borer.

  1. Be sure you’ve identified an ash tree. This is an important first step since EAB only feeds on ash trees. Ash have opposite branching – meaning branches come off the trunk directly across from each other. On older trees, the bark is in a tight, diamond-shaped pattern. Younger trees have a relatively smooth bark.
  2. Look for woodpecker damage. Woodpeckers like EAB larvae and woodpecker holes may indicate the presence of EAB.
  3. Check for bark cracks. EAB larvae tunneling under the bark can cause the bark to split open, revealing the larval (S-shaped) tunnels underneath.
  4. Contact a professional. Tree professionals that are licensed by the MDA are educated in the proper identification and handling of ash trees.  For a list of these contractors please visit: http://www2.mda.state.mn.us/webapp/lis/default.jsp

Emerald ash borer 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. The invasive insect was first discovered in Minnesota in 2009 and is now found in 30 states.  Minnesotans can also help stop the spread of EAB by burning firewood where you buy it and not transporting it. Look for wood that is MDA certified as heat-treated to ensure it is pest-free.
