The emerald ash borer is a serious threat to the ash forest in Pennsylvania. Here is a link to Penn State Fact Sheets on Emerald Ash Borer. You should also go to your local Penn State Extension with samples of the insect so they can report to Penn State entomology. You can also read Homeowners Guide to Emerald Ash Borer Treatment
