The Emerald ash borer, or EAB, an ash tree-killing insect, has now been confirmed in all of Iowa’s 99 counties, with positive confirmation coming from the last county, Emmet County.
EAB was unknown for North America until its discovery in southeast Michigan in 2002.
The invasive, tree-killing insect from Asia has now been found in 37 states.
In 2010, EAB was first discovered in Iowa in Allamakee County.
