Is this the end of the baseball bat?

The flying beetle can kill a healthy, decades-old ash tree in a mere three to five years. It lays its eggs on their bark, which the larvae, once hatched, bore into and consume, eventually starving the tree of water and nutrients. Adult borers can fly only relatively short distances between trees, but people spread them widely when transporting firewood.
