Yes! All day long. All night long. All summer long. Unlike other treatment methods for two-year control of EAB that have to be done in the spring, ArborSystems Wedgle Direct-Inject Tree Injection System and Boxer Insecticide-Miticide (active ingredient Emamectin Benzoate) can be applied until six weeks before the first frost. Trunk injections using our no drilling method and advanced technology for tree treatment are effective anytime the tree is actively growing so the product is translocated with the sap. And you can even inject at night but you probably will need your truck headlights or a flashlight! For more information, click here.
