If you have green, white, blue, or European ash trees growing on your property, understanding the proper timing of trunk injections for Emerald Ash Borer (EAB) is critical to saving them. Untreated trees will die! If you are waiting for EAB to officially be confirmed in your municipality before you make a management decision, the insect is already way ahead of you.
Research has consistently shown that by the time EAB is discovered, it has already been in the area for 3 to 5 years. Because all properties in southeastern Wisconsin are now within a 15-mile radius of a known infestation, we must consider the entire region actively infested.
If you want to save your trees, starting an emerald ash borer treatment program is an urgent priority. Don’t wait until next year!
Why Ash Tree Injections Are the Best Defense Against EAB
There has been an exponential rise in ash tree mortality across the Midwest. If you want to check it out for yourself, tour your surrounding communities. I have personally seen the full impact of EAB devastation in both urban and rural areas of Dayton, Ohio, and Indianapolis, Indiana. Over 90% of untreated ashes are now dead! Significant changes in the tree canopy have occurred. Many of those residents were unprepared for what happened. Too many property owners in Wisconsin remain largely unaware of how quickly this pest destroys native trees.
With EAB pressure on the increase in our region, we utilize professional ash tree injections with Emamectin Benzoate, rather than outdated soil injection treatments that don’t deliver the same effectiveness rate. Our preferred trunk injection delivers the Emamectin Benzoate directly into the tree’s vascular system. This provides a 99% effectiveness rate for two full years, even in high EAB pressure areas. Because the treatment moves through the tree’s natural water transport system, it is best applied during the active spring and summer growing seasons.
Schedule an EAB Treatment Assessment
The key to saving your canopy is immediate, proactive care. An ISA certified arborist must assess the current health of your trees to map out a custom emerald ash borer treatment plan.

Frequently Asked EAB Questions
Can you save an ash tree from EAB?
Yes. An aggressive EAB ash tree treatment program using professional trunk injections can completely protect your tree from dying, provided the tree is still relatively healthy when treatment begins.
What are the signs that my tree needs an emerald ash borer treatment?
The most common signs of an EAB infestation include canopy thinning (dieback) starting at the top of the tree, sprouting new growth at the base of the trunk (epicormic branching), D-shaped exit holes in the bark, and increased woodpecker activity. Because EAB damages the tree from the inside out, a tree can look healthy even while infested, making proactive inspection essential.
