Emerald ash borer confirmed in Clarke County

Emerald Ash Borer

CLARKE CO., Iowa –  The invasive emerald ash borer has been positively identified in Osceola, bringing the total confirmation to 39 counties.

The first Iowa detection was in 2010. A native to Asia, the beetle is considered one of the most destructive tree pests ever seen in North America, according to a news release from the Iowa Department of Natural Resources.

The Osceola discovery came after an Iowa EAB Team member observed symptoms of an infestation in a city-owned tree. Further examination of the tree by peeling bark led to the collection of a larva that was confirmed by national identifiers.

On their own, the beetles can fly short distances but can unknowingly spread farther in firewood. The Iowa EAB Team urges residents to use locally sourced firewood, burning it in the same county it was bought.
