Emerald ash borer is a serious concern for property owners across Pope County. With Minnesota under a statewide EAB quarantine, the green ash and native ash that shade Glenwood\'s lakeshore, Barsness Park, and rural windbreaks are all at risk. An EAB infestation can kill a mature ash within a few years, impacting property values, shoreline stability, and the character of the Lake Minnewaska landscape.

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.
Frequently Asked Questions
Are ash trees in Glenwood at risk for Emerald Ash Borer?
Yes. All of Minnesota is under a statewide EAB quarantine, and ash trees across Pope County are at risk. Green ash and native ash are common in Glenwood's lakeshore plantings around Lake Minnewaska and in rural windbreaks, so proactive trunk injection is the most reliable way to protect valuable trees before infestation takes hold.
What is the process for EAB treatment and how long does it take?
Our EAB treatment uses a trunk injection of a specialized insecticide that protects the tree from the inside out. The process is quick — typically less than an hour per tree — and provides protection for up to two years. For Glenwood ash trees we recommend treating in spring or early summer for the best uptake and results.
