Emerald Ash Borer Has Been in Michigan For Longer Than You Think

Researchers at Michigan State University have discovered evidence that the Emerald Ash Borer most likely arrived in Michigan a decade earlier than previously thought.

The invasive beetle has killed more than 100 million Ash trees in the United States since its initial discovery in southeast Michigan in the early 2000s.

Deb McCullough is a Professor of Forest Entomology at Michigan State University.

She tells WDET’s David Cassleman that her team found evidence that the Ash Borer was killing trees in Metro Detroit by the late 1990s.
