The Treatment, Step by Step
How We Treat Ash Trees for EAB
We protect ash trees with direct trunk injection of emamectin benzoate — the most effective, lowest-impact method available. Here is exactly what happens when our ISA Certified Arborist and Licensed Pesticide Applicator treats a tree on your property.
01 Staging the Injection System
Our ISA Certified Arborist measures each ash tree at diameter breast height (DBH) and meters the exact dose of emamectin benzoate for its size. A sealed, low-pressure injection kit is staged at the root flare — no spraying, no soil drench, and no drift onto your landscape.
02 Drilling the Injection Ports
Small, shallow ports are drilled into the trunk flare — the zone of fastest uptake into the tree’s vascular system. Spacing the ports evenly around the base ensures the treatment is carried to the entire canopy, not just one side of the tree.
03 Setting the Injection Plugs
Self-sealing plugs are seated into each port and connected to the dosing lines. This creates a closed system that delivers the insecticide directly inside the tree, keeping it away from pollinators, pets, and surrounding soil.
04 Direct-to-Vascular Delivery
The tree’s own vascular system draws the emamectin benzoate up into the canopy, where it kills EAB larvae feeding under the bark. A single trunk injection protects the tree for two to three years before retreatment is needed.
