Emerald Ash Borer

Emerald Ash Borer

Emerald Ash Borer (EAB) is an invasive insect from Asia. The larvae eat the wood under the ash tree’s bark, preventing the tree from moving water and nutrients between the tree’s roots and leaves – killing the tree within two to four years.  EAB has killed tens of millions of ash trees in North America since its discovery in 2002.  Emerald Ash Borer has now reached several counties within Iowa. Within the year, urban forestry professionals expect to find more trees infested with EAB.


A statewide quarantine is now in place due to EAB. For residents, if your ash tree is cut down and you plan to use it for firewood, please burn it on site or within your county. All unprocessed ash, such as hardwood firewood, wood chips, ash logs and ash trees for planting, are not permitted to leave the quarantine area. Do not transport the firewood to other areas. Moving it outside Iowa to un-infested states is illegal.
