Protecting Seward County Seat Ash Trees

Seward features historic residential areas and newer developments with valuable ash trees that are currently threatened by the Emerald Ash Borer. Our professional trunk injection service protects these trees using insecticide applied bi-annually during the growing season. EAB is already established in southeastern Nebraska, and without treatment, Seward ash trees face imminent death. Homeowners should start treatment before visible symptoms appear to ensure a high success rate. Waiting until damage is obvious dramatically reduces the chances of saving the tree, so immediate action is required to protect these valuable specimens.

Seward Community Investment

Protecting Seward’s ash trees is an investment in the community’s character and property values. Widespread tree loss would dramatically change the town’s appearance. On your property, mature ash trees provide benefits like reduced cooling costs and higher property values, which justify the cost of bi-annual treatment. We offer free estimates and will only recommend treatment for trees that have a good chance to survive. EAB will not disappear, so ongoing treatment is required indefinitely. Pair your EAB treatment with deep root fertilization to support the tree’s health and maximize effectiveness.

Why University Towns Are High-Risk Areas

Seward’s status as a university town makes it a high-risk area for the spread of EAB. Constant traffic and student movement can inadvertently transport infested firewood into the community. Additionally, university landscaping often has many ash trees that can become breeding grounds for the beetle if not managed well. This combination of factors creates ideal conditions for EAB to establish and spread rapidly through Seward’s neighborhoods. This makes early, preventative treatment even more critical for local homeowners, as eventual infestation is certain for any untreated tree in the area.

Treatment Effectiveness and Resistance Management

DSC00875

Professional trunk injection has a success rate of over 90% when maintained consistently on a bi-annual schedule. The key is to never have gaps in the treatment schedule. If a treatment is missed and the tree becomes reinfested, the damage may become irreversible. Currently, there is no evidence that EAB populations are developing a resistance to the professional products used. The primary reason treatments fail is due to gaps in the schedule or trying to treat trees that are already too damaged. Starting early and staying consistent is the best way to ensure long-term survival 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.
