Safeguarding Elkhorn's Ash Tree Population

Elkhorn features established neighborhoods and newer developments with valuable ash trees that are currently threatened by the Emerald Ash Borer. Our professional trunk injection treatment protects these trees using medicine delivered directly into the vascular system every other year. The threat is severe because this invasive insect has already killed millions of trees across North America and is established throughout Elkhorn. Without treatment, 99% of ash trees will die within a few years of infestation. Homeowners should not wait for symptoms to appear before starting protection, as trees are often too damaged to save by the time signs are visible.

Elkhorn Property Value Protection

Mature ash trees provide significant shade that reduces cooling costs, enhances neighborhood appeal, and adds thousands of dollars to home values. Losing an ash tree means losing these benefits and facing removal costs that can exceed $3,000. In contrast, bi-annual treatment costs a fraction of this and maintains all current benefits. The key is starting treatment before symptoms appear, as preventative treatment has a success rate of over 90%. We recommend pairing trunk injection with deep root fertilization to help trees maintain vigor and resist stress. We only recommend treatment for trees we believe can be saved.

Understanding the Threat to Elkhorn's Trees

North American ash trees have no natural defenses against EAB because they evolved separately for millions of years. The beetle arrived in the United States hidden in wooden shipping materials and has spread relentlessly through natural flight and human transport of wood products. The beetle establishes permanent populations and does not move on or die out naturally. EAB larvae feed on the tissue just under the bark, creating tunnels that destroy the tree’s ability to transport water from roots and sugars from leaves. This disrupted circulation causes progressive canopy thinning and eventual death, typically within 2-4 years of infestation.

Professional Bi-Annual Protection Program

DSC00875

Our program uses a bi-annual schedule, meaning each Elkhorn ash tree receives treatment once every two years for continuous protection. We perform treatments between April and September while trees are actively growing and transporting nutrients. We use trunk injection exclusively because it is the most effective method, as surface sprays cannot reach the feeding larvae. Our process involves placing small needles into the trunk to deliver insecticide directly into the vascular tissue. These injection wounds are minimal and heal quickly through the tree’s natural response. Each treatment provides two years of continuous protection for your trees.

Our Frequently Asked Questions

At Yard Boss, we understand that you may have questions about our services, processes, and how we can help you achieve the perfect lawn.  Whether you’re curious about our lawn care techniques, service areas, or the benefits of professional lawn maintenance, you’ll find the information you need right here. If you have any additional questions, feel free to reach out to our friendly team!

When started preventatively or at early stages of infestation, treatment is highly effective (90%+ success rate). However, we cannot guarantee results because:

  • Infestation severity varies (hidden damage may be more extensive than visible)
  • Tree health and vigor affect recovery ability
  • Environmental stresses (drought, disease) can impact outcomes
  • Treatment timing matters (earlier is better)


What we DO guarantee is that we use professional-grade products, proper application methods, and will honestly assess whether your tree is a good candidate for treatment.

No, the injections do not harm healthy trees. The process is very similar to getting a flu shot at the doctor's office:

  • We use a small needle (about the size of a needle used to draw blood)
  • The needle is carefully inserted into the trunk every 4 inches around the base
  • The injection sites are small and heal quickly
  • The tree naturally compartmentalizes these small wounds as part of its healing response
  • The benefit of EAB protection far outweighs the minimal stress of injection


Think of it this way:
A small injection is a minor stress compared to the certain death from EAB infestation.

Unfortunately, yes. The Emerald Ash Borer has shown no signs of naturally disappearing or "moving on" in any region where it has established. As long as you want to keep your ash trees alive, they will need treatment every other year.

The good news is that bi-annual treatment (every 2 years) provides effective protection when maintained on schedule.

No, EAB will not go away. Complete eradication would require treating every single ash tree, which is impossible because of:

  • Millions of ash trees in forests, parks, and natural areas
  • Trees on unmaintained properties
  • Trees along waterways and in protected conservation areas
  • Cost and logistics of treating every tree


EAB has permanently established itself in North America. The only way to save your ash trees is ongoing treatment.

The Emerald Ash Borer originated in Asia (specifically China, Korea, Japan, and eastern Russia). It accidentally arrived in North America in the late 1990s, hidden in wooden shipping materials (likely pallets or crating) delivered to the Great Lakes region. It was first discovered in Detroit, Michigan in 2002.

Since then, EAB has spread to most of the United States and Canada, killing all untreated ash trees in its path. It spreads through:

  • Natural flight (beetles fly 1-3 miles per year)
  • Human transport of infested firewood, nursery stock, and wood products
  • Movement of infested ash logs and lumber

Simply put, untreated ash trees will die. It's not a question of "if" but "when."

Timeline of an Untreated Ash Tree:

  • Year 1: EAB infestation begins (often no visible symptoms)
  • Year 2: Canopy thinning, epicormic shoots, possible woodpecker damage
  • Year 3-4: Severe decline, 50%+ canopy loss, extensive dieback
  • Year 4-5: Tree death

Death may take several years, but it is inevitable. The mortality rate for untreated ash trees is 99%+.

Additional consequences of tree death:

  • Loss of property value (mature trees add significant value)
  • Removal costs ($500-$3,000+ per tree depending on size and location)
  • Replacement costs (decades to grow a new mature tree)
  • Loss of shade, privacy, and aesthetic value
  • Safety hazard (dead trees can drop limbs or fall)

NOW. Do not wait until you see symptoms.

Critical Timing Information:

  • By the time you notice EAB damage, the tree is already heavily infested
  • Once visible symptoms appear, it may be too late to save the tree
  • Preventative treatment is FAR more effective than reactive treatment
  • The cost of treatment is a fraction of the cost of tree removal and replacement


Treatment is most successful when started:

  • Before any symptoms appear (preventative protection)
  • At first signs of thinning canopy (early intervention)

Treatment is often unsuccessful when:

  • Tree has 50%+ canopy loss
  • Extensive woodpecker damage present
  • Overall severe decline visible

It depends on the severity of infestation:

  • Early symptoms (light canopy thinning, few exit holes): Yes, treatment can still be effective
  • Moderate symptoms (30-50% canopy loss, visible damage): Treatment may help but success is not guaranteed
  • Severe symptoms (50%+ canopy loss, extensive dieback): We will NOT treat these trees—they should be removed


We'll honestly assess each tree during the estimate and only recommend treatment for trees that have a good chance of survival.
