Emerald Ash Borer Injection Service in Mankato, North Mankato, St. Peter, MN & Surrounding Cities
Protect your ash trees from emerald ash borer damage with professional injection treatments that provide up to two years of protection.
The emerald ash borer is one of the most destructive invasive insects to ever affect Minnesota’s tree population. Once an infestation begins, these small beetles burrow beneath the bark and destroy the vascular system that supplies water and nutrients throughout the tree. At Storm, we provide targeted emerald ash borer injection treatments that eliminate active infestations and create a protective barrier inside the tree to prevent further damage. Our injection formula is proven to provide long-lasting protection for up to two full years, keeping your ash trees healthy, green, and strong.
We proudly serve homeowners, business owners, and HOA communities in Mankato, North Mankato, St. Peter, and nearby areas across southern Minnesota. If you’ve noticed thinning canopies, bark splitting, or D-shaped exit holes, don’t wait—call our team today at (507) 344-6500 for a professional inspection.
Why Emerald Ash Borer Injections Are the Most Effective Treatment
Emerald ash borers feed under the bark, which means surface sprays can’t reach them. That’s why trunk injection is the most reliable and environmentally friendly way to stop these insects. During the injection process, our trained technicians deliver a specialized insecticide directly into the tree’s vascular tissue. The formula circulates throughout the trunk and branches, killing existing borers and preventing new infestations before they can start.
Unlike topical treatments that must be reapplied several times per year, our injections provide continuous internal protection that lasts for multiple growing seasons. This method not only saves time and cost but also minimizes exposure to nearby plants, beneficial insects, and groundwater.
Our Emerald Ash Borer Treatment Process
At Storm, we follow a detailed process to ensure your trees receive the most effective protection possible. We begin with a full inspection of your property, assessing every ash tree for early signs of EAB activity. If we find more than 30% canopy dieback, the infestation has likely gone too far and removal may be the best option. However, if less than 30% of the canopy is affected, we can save the tree with our professional injection treatment.
Our licensed technicians carefully drill small access points around the base of the trunk, spaced approximately five to eight inches apart. Into each port, we insert a precision plug and connect a sealed injector that delivers our high-quality insecticide directly into the tree’s vascular system. The process typically takes less than an hour and provides immediate protection that continues to work from within.
Long-Term Benefits of Our Emerald Ash Borer Protection
Our emerald ash borer injection service does more than just eliminate active infestations—it strengthens the overall health of your trees. Once inside, the treatment not only kills larvae feeding under the bark but also prevents future generations from developing. The result is a tree that remains protected for up to two years, without the need for constant reapplication.
Additionally, our injection process promotes better leaf growth, increased resistance to stress, and improved nutrient circulation. By preserving your existing trees, you also maintain the natural shade, curb appeal, and property value they provide. Regular monitoring and timely re-injection every two years will ensure continued protection year after year.
Signs of Emerald Ash Borer Damage
Recognizing the signs of infestation early can make the difference between saving or losing your trees. Common symptoms include:
- Thinning or dying canopy starting from the top down
- Vertical bark splitting or serpentine tunnels visible beneath bark
- D-shaped exit holes from adult beetles
- Woodpecker activity as they feed on larvae
- Epicormic shoots (new sprouts) growing on the trunk or base
If you notice any of these issues, contact Storm immediately for a professional evaluation before the infestation spreads further.
