WINONA, Minn. (WXOW) -- With the spring thaw underway, state officials are urging people in or near Winona and Houston Counties to check their ash trees for signs of the Emerald Ash Borer.
Mark Abrahamson, an entomologist with the Minnesota Dept. of Agriculture, says it's the perfect time of year for homeowners in quarantined areas to inspect for damage. He says one good way is to look for woodpecker damage, because woodpeckers like ash borer larvae, so woodpecker holes may be a sign of an EAB infestation.
Things to look for: check for cracks in the tree bark, and S-shaped EAB larvae "tunneling" under the bark.
State officials urge homeowners who suspect EAB damage to contact a tree service, a city forester, or the Minnesota Dept. of Agriculture so action can be taken to limit the spread of the insects.
