The emerald ash borer (EAB) has now been detected in 64 Iowa counties where it bores into ash trees and feeds on tissues beneath the bark, ultimately killing the tree. Insect samples were collected from Denison (Crawford County), Edgewood (Delaware County) and Clarinda (Page County). Officials with the Animal and Plant Health and Inspection Service of the U.S. Department of Agriculture confirmed these samples positive for EAB.
