Protecting Your Ash Trees: Understanding and Combatting the Emerald Ash Borer

Updated: 6 days ago

There's a formidable foe threatening one of our beloved species: the Emerald Ash Borer (EAB). This invasive beetle, native to Asia, has wreaked havoc on ash tree populations across North America, leaving devastation in its wake. Fellow tree enthusiasts, for armed with knowledge and proactive measures, we can stand up to this formidable adversary.


The Emerald Ash Borer, aptly named for its striking emerald hue and its penchant for ash trees, poses a significant threat to these majestic specimens. Infestation occurs when adult beetles lay eggs on the bark of ash trees, and upon hatching, the larvae bore into the tree, feeding on its inner bark and disrupting its ability to transport water and nutrients. Left unchecked, EAB infestations can lead to the decline and eventual death of affected trees.


So, what can we do to protect our ash trees from the Emerald Ash Borer? Prevention and early detection are key. Implementing a proactive treatment plan is essential to safeguarding the health of vulnerable trees. There are several treatment options available, each with its own merits and considerations.


One effective method is the application of insecticidal treatments, which can be administered through soil injections, trunk injections, or as a surface spray. These treatments target the EAB larvae within the tree, disrupting their life cycle and preventing further damage.


Systemic insecticides can be absorbed by the tree, providing ongoing protection against future infestations. Emmamectin Benzoate has been shown to be the most effective treatment on them market, when done through a trunk injection.


Another approach is the use of biological control agents, such as parasitic wasps, which prey on EAB larvae, helping to naturally control their population. While these methods may take longer to yield results, they offer a sustainable and environmentally friendly solution to the EAB problem.


It's important to note that the effectiveness of treatment may vary depending on factors such as the severity of infestation, tree health, and environmental conditions. As such, it's crucial to consult with a certified arborist to determine the most appropriate course of action for your specific situation.


In addition to treatment, proactive monitoring is essential for early detection of EAB infestations. Keep a close eye on the health of your ash trees, looking out for signs of decline such as canopy thinning, leaf discoloration, and D-shaped exit holes on the bark – telltale signs of EAB activity.


The Emerald Ash Borer poses a significant threat to ash trees, but taking action with proactive measures, we can mitigate its impact and protect these valuable assets in our urban and natural landscapes. Whether from us, or another company, please get your tree injected.
