Emerald Ash Borer

How PPL is responding

The Emerald Ash Borer, a destructive metallic-green insect that likely hitchhiked to America on wooden packing and shipping crates from halfway across the world, is poised to eradicate ash trees along the East Coast. The insect destroys water- and nutrient-carrying tissues under the ash tree bark and kills the tree over a period of years.


The Emerald Ash Borer is poised to eradicate Pennsylvania's estimated 300 million ash trees.
