The Indiana Department of Natural Resources has confirmed that the emerald ash borer has been found in Evansville.
Evidence of the pest was found in trees near the riverfront in Pigeon Township. The DNR says visible symptoms of infestation in trees is difficult to distinguish from other causes of decline during the first few years. Therefore, the pest has likely been in the riverfront area trees for several years, and ash trees in the surrounding areas are already infested.
Arborist Shawn Dickerson encourages property owners to treat ash trees now. He said if property owners wait until ash trees start to show symptoms of infestation, it will likely be too late to save them. Property owners are also advised to have their ash tree inspected by a professional arborist first to determine if the tree is healthy enough and structurally stable enough to save.
Treatment of trees to prevent them from getting EAB should only be done by an Indiana Licensed Pesticide Applicator, which can be verified with the Indiana State Chemist Office by calling 1-800-893-6637.
