It seemed to happen almost overnight. Thousands of trees started dying unexpectedly in SW Ohio. Cincinnati almost went broke trying to keep the invasion from damaging property—or worse.
The killer was a tiny insect known as the emerald ash borer, a new invasive insect from Asia that will wipe out every ash tree in America...unless we do something about it. First found near Detroit in 2002, emerald ash borers have now infested trees in 35 states, from New Hampshire to South Carolina and as far west as Colorado.
