It’s pretty amazing the amount of damage an exotic beetle can cause. Of course, we’re talking about the Emerald Ash Borer. This seemingly innocent insect was first spotted in southeastern Detroit in the summer of 2002. Ever since, the EAB has killed millions of ash trees in North America. In this post, we want to dive deeper into the EAB. Specifically, we want to answer this question: what caused the beetle to appear in the U.S. in the early 2000s?

A Summary of the Emerald Ash Borer

The EAB is truly fascinating. Let’s start with the fact that the adult beetles nibble on ash foliage, but cause little to no damage. It’s what happens next that makes the EAB so deadly. The larvae feed on the inner bark of the tree, effectively disrupting its ability to transport water and nutrients. In a matter of time, the tree dies. So how did this insect wind up finding a home in America? Well, according to the Emerald Ash Borer Information Network, experts believe they probably arrived here on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Today, there are confirmed sightings of EAB in 31 states, as well as the Canadian provinces of Quebec and Ontario.

We already pointed out the number of trees EAB has killed in North America. But it’s also caused regulatory agencies to enforce quarantines and fines to prevent even more of an outbreak. Not surprisingly, the beetle has cost numerous industries hundreds of millions of dollars.
