State insect experts say an invasive species is staying put in one Iowa county.
The Emerald Ash Borer began attacking ash trees in Allamakee County in 2010.
A survey completed this year shows the pest hasn’t moved outside of that county and remains in areas near new Albin and Lansing.
Experts say only Iowans within 15 miles of the infected areas should treat their trees. They say it’s not necessary to treat in the rest of the state.
