Tips on Treating Emerald Ash Borer

EAB - Emerald Ash Borer is destroying ash trees everywhere. 

It is not uncommon for us to have to remove literally 100s of ash trees from Chicagoland neighborhoods that have fallen victim to EAB.

EAB is a beetle,  no larger than a penny, that has killed millions of trees in Illinois and our neighboring states.  EAB originated in Asia and probably made its way to the US in wood packing material.  It's unfortunate, but our ash trees have no line of defense against EAB.

Spring will be here soon and if you didn't notice signs of EAB last year, that doesn't mean your tree(s) aren't victims of EAB.

Here are a few things to watch for this spring. 

1. Your tree could be infested with EAB if you notice a dieback in the canopy of the tree.  EAB strikes the top 1/3 of the canopy first and progresses until the tree is bare.

2. Also, bark that splits vertically and a zig zap pattern across the woodgrain is another tell tale sign of EAB.

3. You may also notice D-shaped exit holes in the bark.  These are exit holes made by the adult beetle when they emerge in the spring.

4. Woodpeckers like EAB larvae, so heavy woodpecker damage is another sign of infestation.

A good thing is that EAB only attacks ash trees, so your other trees should be safe from this bug.


A really important thing to remember is not to move firewood to prevent the spread of EAB.

What to do if you think EAB has made its way to your trees

If you think you have a tree infested with EAB, you'll need to treat it with insecticides, and you'll need to treat it every year thereafter. This is a must.  It is best to treat the tree when it is still healthy.

If you have an ash tree, it is time to get an Emerald Ash Borer (EAB) treatment. 

First and foremost, contact a professional arborist to confirm the EAB infestation and the severity of it to determine the correct treatment or if the treatment will be effective.  A professional tree service company will also have access to some products that are not available to the general public that may work much better than the ones you can purchase locally.  While it is true that you can get some EAB treatments from the bog box stores and other nurseries, these treatments are often ineffective as they are not strong enough to effectively treat the infestation. In order to use the treatments that really work, you need to be licensed. This is where a tree service with professional Certified Arborists on staff comes in. With out the help of a Certified Arborist and qualified tree service, your efforts will probably be an effort in futility. 

Trees "R" Us, Inc., a professional tree service on the North Shore and surrounding suburbs, handles many EAB cases every year.  We have Certified Arborists on staff to help determine if your tree is infested and the best plan of action for your tree.  Our staff is fully trained on how to apply insecticides and which treatments will work on the infestation you have.  Most of our work in concentrated on the North Shore, however we work across Cook, Lake and McHenry counties and see many, many EAB cases each year.  Contact us today for a free estimate.
