What if my Neighbor Doesn’t Want to Treat their Ash Tree

I am frequently asked this question by homeowners concerned that an infested tree next door will somehow doom their ash tree even if they treat for Emerald Ash Borer. I thought it important to not only explain why this is not true but also show some pictures that speak for themselves.

 

In this first photo, the neighbor on the left has been treating their tree with us for several years. The insecticide is systemic, meaning it gets absorbed by the plant tissue and moves throughout the tree into the areas where Emerald Ash Borers feed. As this is a PREVENTATIVE treatment in place before the Emerald Ash Borer attempts to feed on the ash tree(s), any ash borer that touch a treated ash tree (either by feeding on the leaves or burrowing under the bark) cannot survive and complete their life cycle. The ash on the right has not been treated and any ash borer that go after it are not affected at all and will complete their life cycle and emerge as new adults the following season. As we continue treating the tree on the left it is clear that no future Emerald Ash Borer will survive there while the tree on the right will continue to be attacked until it is completely dead.
Here in another neighborhood of hundreds of dead and dying ash trees, another customer of mine has been treating for Emerald Ash Borer for three years. When we started treatment there was no visible signs of infestation in the area but within two years it just exploded. In my opinion there are no other ash trees in this subdivision that can be saved at this point. Treatment needs to begin when your trees still look healthy and the insect has been confirmed within 15 miles of your ash trees. DON'T WAIT UNTIL IT IS TOO LATE TO TREAT! If your trees already look like the background tree, then you have waited too long. They cannot be saved at this point! Contact us now to get your trees inspected!
