What you need to know about the Emerald Ash Borer
For the first time, the Emerald Ash Borer has popped up in Rib Mountain. It was found earlier this month.
Dr. Heather Schlesser with the UW-Extension in Marathon County stopped by NewsChannel 7 at Noon Thursday with what we need to know.
She said the metallic wood-boring beetle attacks ash. It usually kills the trees in one to three years.
Symptoms to watch out for include crown die-back, new growth at the base of the tree, vertical splits in the bark and increased woodpecker feeding. Other signs include 'D' shaped exit holes and 'S' shaped patterns under the bark.
