An invasive beetle has been found in a fourth Iowa county and now officials are considering more quarantine efforts.
The Iowa Department of Agriculture says the Emerald Ash Borer was located in a residential tree in Mechanicsville, in northern Cedar County. A resident contacted local officials after noticing declining ash trees. The Iowa EAB team discovered larvae in several trees in the area.
Officials are considering a regionalized quarantine aimed at slowing the accidental movement of the Emerald Ash Borer by humans. It would restrict the movement of ash firewood, logs, and chips out of quarantined counties.
The pest has previously been identified in Allamakee, Des Moines, and Jefferson counties.
State Entomologist Robin Pruisner says most EAB infestations in the U.S. are started by people transporting firewood, nursery plants, or sawmill logs they didn’t know were infested.
