Sadly, Illinois will lose all of its 130 million Ash trees - except for those properly treated by knowledgeable Arborists. The destructive Emerald Ash Borer is widespread and rapidly expanding. The good news is that although it was once believed to be an untreatable insect, we now know that is not true.
The EAB can live under the bark of an Ash tree for 3 to 5 years before any outward signs of tree disease are evident. Once the EAB population builds to a sufficient level and does enough damage, the tree starts to die rapidly.
Unfortunately, Ash tree owners do not have the luxury of waiting until the EAB is definitively identified in their neighborhood. Homeowners need to assume that this devastating insect is already in their neighborhood and most likely living within their tree, even if no ‘outward signs’ are yet evident. If Ash tree owners wait until the much talked about ‘D’ shaped exit holes are evident at eye level, it will be too late to save the tree!
Emerald Ash Borer must be controlled proactively. Treatment must start NOW!
Tree Green’s Emerald Ash Borer treatment procedure is a two-step process.
- We perform a Soil Drench consisting of a combination of products, which includes an insecticide called Imidacloprid and a rich fertilizer mixture. It is well known that a healthy tree is better able to fight off all types of environmental stressors, including damage caused by insects.
- The second part of the treatment is a tree Trunk Infusion of an injectable insecticide also containing Imidacloprid. Imidacloprid builds up in the vascular system of the tree and will kill EAB larva as it begins to feed.

Why we're so confident in the effectiveness of our treatment
In September 2006, we visited Michigan and met with a Board Certified Master Arborist who was involved in the initial identification of the ‘EAB’ in his state. His area near Detroit is ‘ground zero’ for the Emerald Ash Borer. He created an innovative treatment program, and the results were amazing to see. He took us to several locations including subdivisions, malls, and apartment complexes. We saw the same thing in and around every location: full, healthy, vibrant Ash trees that were treated by this Arborist’s company, but surrounded by literally thousands of untreated dead Ash. The forest preserves, wooded lots and parkways looked as if a selective forest fire had gone through those areas, destroying only Ash trees. The devastation was very, very sad. But in the midst of the sea of dead Ash was the occasional green oasis, where this Arborists’ healthy, treated Ash trees stood, and still stand today! After seeing this Arborist’s success first-hand there is no way we would offer a less-proven method.
Which Ash trees to save?
A homeowner should assess their property and determine which Ash tree or trees are most valuable to their landscaping design. Is the tree well located? Does it provide shade to the patio, deck or the house itself? How many years will it take to grow a new tree of that size in its place? Does it add value to the property due to its aesthetic appeal? If the answer is yes to any of these questions, then the tree may certainly be worth treating and saving!
