MUSCATINE, Iowa — Officials with the Iowa Department of Natural Resources say the larva of an invasive beetle has been found in Muscatine County.

That brings the total of Iowa counties the Emerald Ash Borer has been confirmed in to 11. The larva was found in a residential tree in Muscatine and collected by the Iowa EAB Team.

“The Iowa EAB team continues to respond to reports of suspected infestations as we work to monitor its movement and hopefully slow the spread. Iowans are again reminded to not move firewood as that is the quickest way to start a new infestation,” says State Entomologist Robin Pruisner.

The larva of the Emerald Ash Borer digs its way under the bark of Ash trees and eventually kills them.

The destructive pest has already been located in Allamakee, Des Moines, Black Hawk, Bremer, Cedar, Henry, Jasper, Jefferson, Union and Wapello counties.

If you are worried you may have an infestation, you can contact the EAB Team and they will investigate. Learn more here
