What Kills The Emerald Ash Borer?

It seems like the emerald ash borer is being discovered in a new region every month. As of May 2018, the pest has been found in 33 states, as well as the Canadian provinces of Ontario, Quebec, and Manitoba. Since its discovery in 2002, EAB has killed hundreds of millions of ash trees in North America and cost hundreds of millions of dollars in damage.

So what’s the most effective treatment for EAB? Here are a few options worth considering:


Soil drench

This seems to be the most common EAB treatment today among homeowners. Your tree will absorb the diluted insecticide through its roots, killing the pests as they feed on the trunk tissue that’s drenched in the solution. Whichever product you choose, the key ingredient worth noting is imidacloprid.

Keep in mind that imidacloprid is the only chemical approved for use by homeowners. Your local certified arborist should have access to more powerful, long-term products.

Bark and foliar application of insecticide

This could be a potential treatment if you have small ash trees. Homeowners can use insecticides containing carbaryl and acephate and inject them directly into the bark. Unfortunately, results aren’t guaranteed with such a DIY approach.

Your best bet is to get in touch with a professional tree service regarding EAB. They will have the specialized equipment and products used to treat full-size trees. Not to mention, they may be able to eliminate the pest without doing further damage to the tree.

Destroying dead wood

It’s imperative to take action before a serious EAB infestation begins. What do we mean by this exactly? Well, if an ash tree dies from borers, it should be cut down during the colder months and disposed of properly before additional young beetles emerge the following spring.

Here at Schra Tree Care, we are often asked what happens to infested ash trees. As you can see for yourself on the Emerald Ash Borer Information Network, the leafy canopy of infested trees begins to look thin. The borer essentially strangles the tree as it chews through the tree’s water and nutrient-conducting tissues.

Unfortunately, anywhere from a third to a half of the branches may die in less than a year. Most of an ash tree’s canopy will be dead within two years of when initial symptoms are noticeable.
