DES MOINES, Iowa (KCRG) - The Emerald Ash Borer (EAB) has been confirmed in Grundy County.
Insect samples on a city-owned tree in Dike were positively identified as EAB by a federal identifier.
The EAB has been found in 65 Iowa counties total.
The adult ash borer is metallic green and measures about one-half inch long. It can be noticed during the summer months.
Infected trees usually lose leaves at the top of the canopy and the die-off spreads downward. Trees usually die within two to four years. A federal quarantine, enforced by the U.S. Department of Agriculture, remains in effect restricting movement of hardwood firewood and ash articles out of Iowa into non-quarantined areas of other states.
Iowans should use only local firewood.
