The Emerald Ash Borer is a highly destructive beetle that is infesting our ash trees, killing them at an alarming rate. All ash trees are expected to become infested and die unless they are treated by an arborist.

The Emerald Ash Borer, native to China and eastern Asia, is an exotic beetle that was found for the first time in southeastern Michigan in May 2002. Experts believe this beetle most likely was introduced to North America accidentally – and was transported in wooden packing and crating material.
In their adult form, these beetles feed on ash foliage, causing little damage. However, their larvae, that feeds on the inner bark of ash trees, disrupts the tree’s ability to transport water and nutrients and ultimately kills the tree.
