Emerald Ash Borer Treatment

An Emerald Ash Borer (EAB) infestation was confirmed in Vadnais Heights in the summer of 2019 by the MN Department of Agriculture. 

What is Emerald Ash Borer?


The Emerald Ash Borer (EAB) is an invasive beetle from Asia that was discovered in the United States during the summer of 2002 near Detroit, Michigan. EAB larvae feed on the inner bark of ash trees and disrupt the tree‘s ability to transport water and nutrients, killing the tree. Once an ash tree is infested, it has almost zero chance of survival unless it is treated in time. EAB populations can grow exponentially each year because the beetle has few natural predators and our ash trees have limited natural defenses.  When EAB is not managed, annual ash tree deaths can quickly overwhelm the ability to remove dead and dying trees.

Management Program

As the city considers any potential action regarding EAB, updates will be posted to this page.
