FIGHT EMERALD ASH BORER: Early detection is key to fighting the emerald ash borer (EAB), a destructive tree insect. Arborjet, a company dedicated to developing remedies for saving ash trees, offers tips on how to spot the emerald ash borer. Look for:
- Canopy dieback – Beginning in the top 1/3 of the tree, leaves stop growing to the tips of the branches and progresses until tree is bare.
- Shoots from the roots – Sprouts grow from the roots and trunk, and leaves often appear larger than normal.
- Splits in bark — Vertical fissures appear on bark.
Grooves and D-shaped exit holes – Feeding galleries, or grooves, for larvae weave back and forth under the bark. Adults form D-shaped holes when they emerge from under the bark.
- The markings (larval feeding galleries) left from emerald ash borer larvae on an ash tree. The invasive pest has killed tens of millions of ash trees in the United States and Canada.
- Increased woodpecker damage – These birds peck at outer bark while foraging, and create large holes while extracting insects.

We can now fight back! There is a product, TREE-age, by Arborjet, that we can inject every other year that has shown over 90% control of the larvae that kill the tree. The injection is best done as a preventative, but we have had some success in trees with limited infestations.
The trees are dosed in milliliters. For example, a 12″ diameter ash requires just over 40 milliliters of TREE-age and costs about $150 + tax, every other year. Not a whole lot of money to protect a prominent ash tree in your landscape.
If you have any ash trees that are currently not under our care, please contact us for a no-cost or obligation inspection to provide our recommendations. We might be able to protect your valuable ash tree, allowing you to enjoy its benefits for many years to come. And, if you have any neighbors or friends with ash trees, we always appreciate a referral. Call us at 440-4521-9589 or email email@example.com.
