You can control the ash borer with an injection of Pointer (Imidachloprid) directly into the cambial area with the “Wedgle” Direct-Inject Tree Injection System. This injection method places the chemical directly where the insect is active without harming the tree like other drilling methods.


Other methods of treatment such as TreeAge require a large hole to be drilled into the tree itself. This can cause significant stress to a tree, and if done repeatedly could lead to significant damage. One application per year will kill the borer larvae and prevent further damage.

The “Wedgle” is manuafactured by ArborSystems Inc. If you would like to read more about the Wedgle method, please call our office at 630-480-4090 or visit
