The Emerald Ash Borer (EAB) is a small, metallic green beetle native to northeastern Asia. Since its discovery in North America in 2002, EAB has become one of the most destructive invasive species for ash trees, causing the death of millions of trees across the United States and Canada. The beetle’s larvae burrows into the ash tree’s bark, disrupting the tree’s ability to transport water and nutrients and eventually leading to its death. Given the severity of the threat, specialized tree services have become essential in managing and treating EAB-infested trees. Tree Craft Tree Service would like to explore the important role of professional tree services in combating the Emerald Ash Borer and preserving ash tree populations.
What is the Problem with the Emerald Ash Borer?
The Emerald Ash Borer’s lifecycle and feeding habits make it a formidable opponent. Female beetles lay eggs in the crevices of ash tree bark, and upon hatching, the larvae feed on the inner bark, creating serpentine galleries that cut off the tree’s flow of nutrients and water. Signs of EAB infestation include thinning and yellowing leaves, D-shaped exit holes in the bark, and canopy dieback starting from the top. Once symptoms are visible, the tree is often already significantly damaged, underscoring the need for early detection and intervention.
How to Tell if an Ash Tree is Infected with Emerald Ash Borer?
The first step in addressing an EAB problem is accurate identification and assessment, services best performed by certified arborists. These professionals can distinguish between EAB damage and other tree health issues, ensuring that treatments are appropriate and effective. Arborists use a combination of visual inspections and, when necessary, more invasive techniques like branch sampling to confirm the presence of EAB.
What are the Control Methods for EAB?
Effective EAB management often requires an Integrated Pest Management (IPM) approach, combining multiple strategies to control the beetle population while minimizing environmental impact. Professional tree services offer several IPM solutions:
• Chemical Treatments – Insecticides are a primary defense against EAB, with options including soil injections, trunk injections, and bark sprays. These treatments are most effective when applied early in the infestation. Certified applicators ensure that chemicals are used safely and effectively, with consideration for protecting non-target species and the environment.
• Biological Control – Biological control involves introducing natural predators of EAB in affected areas. Several species of parasitoid wasps, for example, have been released as part of biocontrol programs. Tree service professionals work in coordination with local and federal agencies to support these efforts where appropriate.
• Tree Removal and Replacement – In cases where trees are too severely infested to save, professional tree services can safely remove and dispose of these trees to prevent further spread of EAB. They can also advise on suitable replacement trees that are not susceptible to EAB, helping to restore the urban canopy.
• Preventative Tree Care – For ash trees not yet infested or in the early stages of infestation, preventative care can be vital. This includes proper mulching, watering, and fertilization to boost the tree’s health and resistance to EAB.
