- Identifying the bug: overall bright, metallic, emerald green color overall, possibly with brass or copper tints
- Identifying an infected Ash tree: branch dieback, tree dying from the top down (no leaves at the top), sprouting from the base of the tree, increased woodpecker activity at the tree
- The Emerald Ash Borer leaves distinct 1/8-inch D-shaped exit holes, and beneath the bark they leave a serpentine pattern in the tree that is filled with sawdust.
- The Emerald Ash Borer originates in Asia and was accidentally introduced in southeastern Michigan. In 2003, the Emerald Ash Borer was found in Ohio. The Borer has no natural predators here, and our Ash trees cannot fight off the bug at this time.
- The Borer feeds on the living tree, right beneath the bark. This feeding activity prevents the tree from moving water and nutrients, and within 3-5 years the tree will be dead.
- Before the introduction of the Borer, Ohio had roughly 5 billion Ash trees. As of 2006, only about 254 million Ash trees were counted in Ohio (USDA Forest Service 2006, Forest Inventory Analysis Program).
- DO NOT MOVE FIREWOOD. Infested firewood transports the Emerald Ash Borer to new areas and spreads the infection.
- If you suspect that you have infected Ash tree(s) on your property, contact an arborist to come evaluate (and probably remove) them before the pest spreads to other areas.
No doubt, many of you have heard about the Emerald Ash Borer and its destructive nature, especially with its introduction to Ohio in 2003. Nevertheless, for those of you who are not familiar with the pest, here is some quick information to help you identify the pest, identify infected trees, and do your part to stop the spreading.
