Emerald Ash Borer (EAB)
The Emerald Ash Borer (EAB), confirmed in Milwaukee in 2012, is an invasive wood boring beetle that can kill ash trees within 2-4 years. It is estimated that nearly 50 million ash trees have been killed by EAB in the Midwest since 2002. EAB infestation is extremely difficult to detect and often goes unnoticed until more advanced symptoms such as dead branches, leafy trunk sprouts growing near the base of the tree, or bark flecking caused by woodpecker feeding is noticed. Trees found in this condition are often too infested to save.
To help Milwaukee residents with ash trees on their private property prepare for EAB, the Department of Public Works (DPW) Forestry Division identified and mapped over 15,000 parcels in the city with ash trees at risk for EAB. Milwaukee residents with ash trees on their property are encouraged to consider treatment or removal/replacement options prior to their tree becoming infested.
