Emerald Ash Borer—Where Is It In Nebraska and When Should Tree Owners Treat For It?
By Kathleen Cue

The much-dreaded emerald ash borer (EAB) was identified in Douglas County in 2016. Since that time, EAB has been found in several other locations that holds implications for counties in the eastern part of Nebraska.
Infestations of this insect are known to kill ash trees in a relatively short time period—from 3 to 5 years in most cases. Once an ash tree is dead, the tree quickly becomes brittle and is a threat to nearby homes, vehicles, and yes, people.
