Do you know the signs of an emerald ash borer (EAB) infestation? The galleries pictured above indicate EAB damage to the trunk of an ash tree.

The Real Truth About Emerald Ash Borer

September 16, 2014

In the world of pests, emerald ash borer (EAB) is certainly the “buzz” in several regions of the U.S. and Canada this year—but its capabilities are old news.

From Baltimore and Connecticut, to St. Louis and Boulder, the lean, mean, green-eating machine continues to establish its presence in communities that now face situations requiring them to make decisions about their ash trees. Yet, as scientists continue to research the best solutions to conquer EAB, the ash tree species continues to decline in the pest’s path.

So, what does this mean to you?

Karl Dreyer, district manager for Davey’s St. Louis tree services, reveals two truths about EAB in his St. Louis KTRS, NewsRadio 550 interview:

Q: I got a notice here that EAB has been found in St. Charles County. Is there any truth to that?

Dreyer: That is a true statement. It has been positively identified in St. Charles County. If it’s not here, it’s awfully darn close.

We’re recommending first, be aware that there’s a pest. Then, if you can identify any ash trees in your property, have an arborist take a look and evaluate them. Make sure they don’t have any symptoms of EAB.

Q: Is there any truth that those trees can be treated?

Dreyer: Yes, you can treat them. There are some different options as far as treatment goes. All of them, for the most part, consist of a systemic insecticide that you can introduce to the tree through the roots or the bark, or inject in the trunk.

Insecticides have a variety of effectiveness in terms of the length of time that they treat—some products treat for a year, some treat up to two years. The trunk injection method is probably the most preferred at this point because it is most effective that we know of. Plus, it provides two years of control.

I spy EAB? Stay tuned to our blog this week to read about an exciting scavenger hunt for these tiny, metallic green pests, led by one of Davey’s own district managers.
