Emerald ash borer has killed hundreds of millions of ash trees across North America and is now established in Stearns County. Every untreated ash tree in St. Cloud is at risk. Total Control Tree Service provides professional emerald ash borer treatment that protects healthy ash trees and can save trees in early stages of infestation. Treatment works. Removal costs 5 to 10 times more than protection. We are licensed, bonded, and fully insured with ISA-affiliated arborists trained specifically in EAB management.
Your ash tree does not have to die. Treatment started today can protect it for decades.
Understanding Emerald Ash Borer in Central Minnesota
How EAB Kills Trees:
- Adult beetles lay eggs in bark crevices
- Larvae hatch and bore into cambium layer
- Larvae feed creating S-shaped galleries under bark
- Galleries sever vascular tissue that moves water and nutrients
- Tree starves and dehydrates from the inside
- Death occurs within 2 to 4 years of initial infestation
Why EAB Spreads So Fast:
- Adults fly up to 10 miles seeking new host trees
- Firewood transport moves infested wood to new areas
- No natural predators effectively control population
- All ash species are susceptible regardless of health
- By the time symptoms appear, infestation is advanced
Current Status in Central Minnesota:
- EAB confirmed throughout Stearns and Kandiyohi counties
- Infestations spreading through St. Cloud, Sartell, and surrounding communities
- Municipal ash trees being removed across the region
- Private property ash trees dying without treatment
Signs Your Ash Tree Has Emerald Ash Borer
Early detection improves treatment success. Watch for these symptoms.
Canopy Symptoms:
- Thinning starting at top of tree and progressing downward
- Yellowing leaves earlier than normal fall color
- Fewer leaves each successive year
- Dead branches appearing in upper canopy
Trunk and Bark Symptoms:
- D-shaped exit holes approximately 1/8 inch wide
- Vertical bark splits exposing galleries beneath
- S-shaped larval galleries under loose bark
- Increased woodpecker activity and bark flaking
Other Indicators:
- Epicormic sprouting along trunk and major branches
- Excessive seed production as stress response
- Bark falling off in chunks revealing feeding damage
If you see these signs, call immediately. Earlier treatment means better outcomes.

How We Treat Emerald Ash Borer in St. Cloud
Total Control Tree Service uses trunk injection, the most effective EAB treatment method available.
Why Trunk Injection:
- Delivers insecticide directly into vascular system
- 100 percent of product reaches target tissue
- No environmental exposure or drift
- Works even during drought when soil treatments fail
- Provides 2-year protection per treatment cycle
Our Treatment Process:
- Assessment of tree health and infestation level
- Trunk diameter measurement for accurate dosing
- Injection ports placed at trunk base
- Treatment injected using calibrated equipment
- Tree uptakes product within hours
- Protection established throughout canopy
- Retreat scheduled before protection expires
Treatment Products: We use emamectin benzoate, the most effective and longest-lasting EAB treatment available. This product provides approximately 2 years of protection per application and has the strongest research support for EAB control.
When to Treat Ash Trees for EAB
Timing affects both urgency and treatment success.
Treat Now If:
- Tree shows no symptoms but EAB is in your area
- Tree has minor canopy thinning (less than 30 percent)
- Tree has high value for shade, aesthetics, or sentiment
- Removal cost would significantly exceed treatment cost
Treatment May Not Be Appropriate If:
- Canopy loss exceeds 50 percent
- Tree has significant structural defects beyond EAB damage
- Tree was already declining before EAB arrival
- Removal is planned for other reasons
The Window Closes: Once a tree loses more than 50 percent of its canopy, treatment success rates drop dramatically. Trees caught early respond well. Trees caught late often cannot recover even with treatment.
Treat vs. Remove: Making the Right Decision
We help you make the best choice for your property and budget.
Factors Favoring Treatment:
- Tree is healthy aside from early EAB symptoms
- Tree provides significant shade or energy savings
- Tree is large and would be expensive to remove and replace
- Property value would decrease substantially without tree
- Sentimental value makes preservation important
- Treatment cost is reasonable relative to tree value
Factors Favoring Removal:
- Tree is already heavily damaged (over 50 percent canopy loss)
- Tree has other serious health or structural problems
- Tree is in poor location and would not be replaced
- Treatment commitment is not feasible long-term
- Tree is small and easily replaced
The Math: A typical 20-inch ash tree costs $150 to $300 to treat every 2 years. Removal and replacement costs $2,000 to $5,000 or more. Treatment for 20 years costs less than one removal.
What Affects EAB Treatment Cost in St. Cloud
Treatment cost is straightforward and based on tree size.
- Trunk diameter at breast height (DBH) determines product volume
- Number of trees requiring treatment
- Current health status and treatment urgency
- Accessibility and site conditions
- Ongoing treatment program versus single application
New customers receive 10% off service over $500.

What Happens to Untreated Ash Trees
Understanding the timeline helps you act before options disappear.
Year 1-2: EAB arrives but symptoms not visible. Treatment at this stage has highest success rate.
Year 2-3: Canopy begins thinning at top. Treatment still highly effective.
Year 3-4: Significant canopy loss, epicormic sprouting, bark damage visible. Treatment success declining.
Year 4-5: Tree dies. Removal required. Dead ash becomes brittle and hazardous quickly.
After Death: Wood becomes extremely brittle within 1-2 years. Removal costs increase due to hazard. Branches and tops break unpredictably.
The treatment window is 2-3 years from initial infestation. Once that window closes, removal is the only option.
