Emerald Ash Borer in Omaha: 2024 Update
An invasive insect continues to threaten ash trees across the Midwest, and its presence in Omaha remains a serious concern. Since the Emerald Ash Borer was first identified locally in 2016, ash tree populations have experienced increasing stress and decline. As a result, many property owners and municipalities now face difficult decisions about long-term tree care.
As of 2023, ash trees account for approximately 14% of Omaha’s urban forest. Consequently, a significant portion of the city’s canopy remains at risk. For this reason, understanding current trends and treatment options is essential for protecting these trees and maintaining long-term canopy health.
Ash Tree Mortality Rates and Current Predictions
Early research projected near-total mortality for untreated ash trees within ten years of infestation. Over time, long-term data has largely supported those projections.
By year nine, an estimated 30% of untreated ash trees experience mortality. By year ten, losses increase to approximately 55%, and by year eleven, mortality can exceed 80%. At this stage, these figures confirm that the impact on local ash populations has been substantial. However, with proactive management, further losses can often be reduced.
Emerald Ash Borer Treatments for Ash Tree Protection
Currently, trunk injection treatments remain one of the most effective tools for protecting ash trees from continued pest pressure. This approach delivers insecticide directly into the tree’s vascular system, thereby providing targeted control while minimizing environmental exposure.
In addition, research consistently shows that properly timed treatments—typically applied in spring or early summer during active growth—offer reliable protection for one to two years, depending on the product used. As a result, treatment timing plays a critical role in overall effectiveness.
