DES MOINES, Iowa — An invasive and destructive beetle has been discovered in another Iowa county.

Officials with the Iowa Department of Agriculture have confirmed the emerald ash borer’s presence in Dubuque County in eastern Iowa. The pest has been found in 28 of Iowa’s 99 counties.

The larvae of the emerald ash borer burrows under the bark of ash trees and causes damage that eventually kills the tree.

“Iowa now has seven counties bordering the Mississippi River that have turned up positive for EAB,” says Mike Kintner, with the Iowa Department of Agriculture. “Unfortunate as it is, I wouldn’t be surprised to see the remaining three counties declared positive within a year.”

A statewide quarantine restricting the movement of hardwood firewood is in place to help halt the spread of EAB.
