Emerald Ash Borer Confirmed in Nebraska 

The Nebraska Department of Agriculture (NDA) confirmed the first find in the state of emerald ash borer (EAB), an invasive beetle that attacks and kills all species of ash trees, in a tree located in Pulaski Park in Omaha. Nebraska will be the 27th state to confirm the presence of the pest since 2002.

EAB is a small, metallic-green beetle that is about ½ inch long. The larvae of this wood-boring insect tunnel under the bark of ash trees, disrupting the flow of water and nutrients, ultimately causing the tree to die. EAB infested ash trees will exhibit thinning or dying branches in the top of the tree, S-shaped larval galleries under bark, D-shaped exit holes and suckers (along the trunk and main branches).

The Nebraska EAB working groups offers the following suggestions to help prevent the human-assisted spread of the pest:

  • Use locally sourced firewood, burning it in the same county where you purchased it. Firewood is a transportation vessel for the pest.
  • Only high value ash tress located within 15 miles of a known infestation should be considered for treatment. Trees that are experiencing declining health should be considered for removal.
  •  If you feel you have located an EAB infestation, please report it to the Nebraska Department of Agriculture at (402) 471-2351, the Nebraska Forest Service at (402) 472-2944 or your local USDA office at (402) 434-2345.
