The cities of Monticello and Elk River, nestled along the Mississippi River, are seeing a rapid increase in Emerald Ash Borer infestations. This invasive pest threatens the significant ash population in our residential neighborhoods, city parks, and natural areas like the Bertram Chain of Lakes Regional Park. Without professional intervention, these beautiful and mature trees are at high risk of being lost forever, impacting property values and the local ecosystem that defines our communities. Proactive trunk injection treatments are the most effective way to save them.
At Timber & Native, our ISA Certified Arborists and MN Licensed Pesticide Applicators provide targeted, effective EAB treatments to protect your ash trees. We utilize a proven trunk injection method that delivers insecticide directly into the tree's vascular system, providing two years of protection from the inside out. This approach is safe for your family, pets, and the surrounding environment, and is far more effective than soil drenches or sprays, especially in areas with sandy soils common to the region. Don't wait until your ash trees show signs of decline; early detection and preventative treatment are critical for their survival.

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
My property is near the Mississippi River in Elk River. Is trunk injection safe for the watershed?
Yes, our trunk injection method is a closed-system process that delivers the product directly into the tree. This prevents any runoff or contamination of nearby water sources like the Mississippi River, making it the most environmentally responsible EAB treatment option.
We have several large ash trees in our yard in a new Monticello development. When should we treat them?
The best time to start protecting your ash trees is now, even if they look healthy. EAB can be present for years before visible signs of decline appear. Proactive treatment is the most effective and affordable way to ensure their long-term survival and preserve the canopy of your new property.
Is it too late to save an ash tree that already has some dead branches?
Not necessarily. If the tree has less than 30-40% canopy decline, it can often be saved with a professional trunk injection. Our ISA Certified Arborists can assess your tree's health and provide an honest recommendation on whether treatment is a viable option.
