Do I have an Ash Tree?

As you may know by now, Ash Trees are under attack by a tiny little insect called the Emerald Ash Borer and you could be aiding its survival and infestation.


It is a very good idea to identify whether or not you have any Ash Trees on your property as you may have the opportunity to increase your property value and prevent further destruction to your shade trees.


There are resources available that can help you determine whether or not you have any Ash Trees on your property or you can contact Midwest Tree Service and we will give you a free assessment of your trees.

What is the Emerald Ash Borer?

 The Emerald Ash Borer was first discovered around Detroit Michigan in 2002 and has now been identified in 29 states and regions of Canada. This invasive little insect has now infected Ash Trees in 55 counties in Iowa so far. But it's not the beetle that is causing the devastation, it is the larvae that burrows into the bark of the Ash Tree and feeds on the soft tissue behind the bark, destroying the flow of nutrients the tree needs to survive. The Emerald Ash Borer is not native to the US and arrived by being accidentally transported to the US by riding in and on the wood of freight pallets and crates from Asia.


 The Emerald Ash Borer is not known to be selective in what Ash Trees it destroys. Most borers will choose sick or weaker trees to live in but that is not the case with the Emerald Ash Borer. The female will lay her eggs on any healthy or stressed Ash Tree for the larvae to feed on. The larvae will live inside the tree for a few years before emerging from a "D" shaped hole in the tree. The adults will then feed on the leaves of Ash Trees and other vegetation. The Emerald Ash Borer life expectancy is only a few weeks so as soon as they emerge from their hole they fly to another area with Ash Trees and lay their young on the bark, spreading their devastation.

Dealing with Emerald Ash Borer

Usually Ash Trees wont show immediate signs of being infected by Emerald Ash Borer. Indications usually can be first found behind the bark of the tree. As depicted above, there will be "S" shaped burros in the vascular tissue of the tree, which is unique to the Emerald Ash Borer larvae.


Treatment or Removal

There are a couple options for dealing with infected Ash Trees. If the tree appears to have lost more than 40% of its foliage then the tree will have to be removed. If the damage appears to be less than 40% there is a chance that it can be saved by being treated.


There are a few options for treatments but the most effective treatments are done through injections into the base of the tree. Midwest Trees Service uses Arborjet systems, which are known to be the best in the industry. Your Ash Trees will be treated by a certified applicator ensuring your trees will be given superior treatment.

Ash Trees' Environmental Impact

Ash Trees are an essential part of our surrounding environment and serve many very important purposes. There is 1 Ash Tree for every 5 trees  and it is inevitable that every Ash Tree will, at some point, be infected by the Emerald Ash Borer.


Ash Trees are one of nature's effective air scrubbers. One full grown Ash Tree can absorb over 40 pounds of carbon dioxide a year and produce around 250 pounds of oxygen annually.  They are excellent in controlling ground erosion by absorbing 27 times more water in their roots than soil can hold. Each year the Ash Tree also absorbs 2,400 gallons of water through its leaves, reducing the amount of waste water going through drainage systems and water treatment plants. Ash Trees that grow around residential areas decrease energy costs by cooling the air and providing shade for homes and businesses in the warmer months. In the cooler months they lose their leaves, allowing the sun to melt snow and reduce the cold and the energy costs associated.
