An invasive pest that destroys Ash trees has been found in a third Iowa county.
Iowa officials say the Emerald Ash Borer has been discovered in a residential tree in Jefferson County, in the city of Fairfield.
The larvae of the Emerald Ash Borer beetle kills ash trees by burrowing below the bark and eating the actively growing layers of the tree. Officials say the insect is one of the most destructive tree pests ever seen in North America.
A multicounty quarantine will be issued shortly in southeast Iowa, preventing hardwood firewood, ash logs, and wood chips from being moved out of counties without a permit.
Officials caution Iowans to not transport firewood across county or state lines because that is how the infestation spreads.
Emerald Ash Borers have previously been discovered in Allamakee County and Des Moines County.
