The emerald ash borer was found in Lincoln this week.
The Nebraska Department of Agriculture announced Wednesday that the tree-destroying insect was recently found in a trap in an undisclosed location in Nebraska’s capital city. The department also said an arborist in Fremont found signs of an infestation there.
There are also confirmed infestations in Douglas and Cass Counties. The emerald ash borer was first found in Nebraska in June 2016.
Arborist Nicole Stoner at the University of Nebraska Extension office in Beatrice says Saline, Gage and Jefferson County don’t need to treat their ash trees yet, but her and other arborists are always on the lookout.
“We’re recommending you wait until the emerald ash borer is found within 15 miles of your tree before treating,” Stoner said. “Gage, Jefferson and Saline (counties), we’re all still out of that treatment area.”
The emerald ash borer gets its name because its larva bore under the bark of ash trees, usually killing them within a few years.
Once the insect arrives, it usually kills 75 percent or more of all ash trees within a decade.
