DUBUQUE (KWWL) -

The Iowa Department of Agriculture says emerald ash borer has been found in Dubuque County.

The emerald ash borer is a highly destructive insect that chews into the layer of wood just under the bark and cuts the flow of water and nutrients to the tree, eventually causing it to die.

Emerald ash borer, a small, metallic-green beetle, was first discovered in Michigan in 2002 and has spread to 25 states. The insect has killed tens of millions of trees across the country.

Dubuque County is the 28th county in Iowa where EAB has been discovered. Larvae was discovered in the southern part of the county along with a location just south of the city limits.

“Iowa now has seven counties bordering the Mississippi River that have turned up positive for EAB,” Mike Kintner, Iowa Department of Agriculture and Land Stewardship EAB and gypsy moth coordinator, said in a written statement. “Unfortunate as it is, I wouldn’t be surprised to see the remaining three counties declared positive within a year.”
