Emerald Ash Borer
In dealing with Emerald Ash Borer (EAB) in Ash trees, as an Arborist and a Beekeeper, my first goal is to educate customers. I want them to have the information to make a choice that takes into account tree health, pollinator health and the least toxic treatment options.
I always evaluate the tree health first; location and long term viability of the tree before considering treatment. If a tree has major damage or is in the wrong place such as under power lines or too close to a house, it would probably be best to remove tree and replant with a better species in a better location. Newly planted or Small Ash trees may be best to just remove and replant with a better species of tree.
If a customer has a high value Ash tree (healthy, large, provides most of the shade in their yard, provides habitat) then I provide treatments once a year in attempt to save their Ash tree. Tree Azin is a Neem Oil extract and is considered an organic treatment. No treatment is perfect but Tree Azin is the least toxic approach for EAB. Bees are not affected by Tree Azin but other beneficial insects such as Lady Bugs can be negatively affected.
