The Threat of Ash Borers

Ash trees are facing a significant threat in 2023 – the ash borer. These invasive insects have been wreaking havoc on ash tree populations across North America for years, causing widespread devastation. If left unchecked, ash borers can kill an ash tree within a few years. However, there are steps you can take to save your ash trees from these destructive pests.

Identifying Ash Borers

Before you can save your ash trees, you need to be able to identify the signs of an ash borer infestation. Look for D-shaped exit holes on the trunk and branches, serpentine galleries under the bark, and thinning foliage. If you notice any of these symptoms, it’s crucial to take action immediately to prevent further damage.

Preventive Measures

One of the most effective ways to save ash trees from ash borers is through preventive measures. Begin by keeping your trees healthy and stress-free. Regularly water and fertilize them, and prune any dead or dying branches. Additionally, consider applying insecticides specifically designed to target ash borers. These treatments can be applied as soil injections, trunk injections, or as a spray.

Biological Control

Another option for saving ash trees is through biological control methods. Certain species of parasitic wasps are natural predators of ash borers and can help control their population. By releasing these beneficial insects into your ash tree’s environment, you can reduce the number of ash borers and protect your trees.

Chemical Treatments

If your ash trees are already infested with ash borers, chemical treatments may be necessary. Insecticides containing active ingredients such as imidacloprid or emamectin benzoate can effectively kill ash borers and protect your trees. However, it’s crucial to follow the instructions carefully and consult with a professional arborist before proceeding with any chemical treatment.

Quarantine and Removal

In severe cases where ash borers have caused irreversible damage or when it’s too late to save the trees, quarantine and removal may be the only option. By isolating infested trees and removing them from the area, you can prevent the spread of ash borers to healthy trees and minimize their impact on the ecosystem.

Monitoring and Early Detection

Regularly monitoring your ash trees for signs of ash borer infestation is crucial for early detection. By catching the problem early on, you have a better chance of saving your trees. Stay informed about ash borer outbreaks in your area and be proactive in implementing preventive measures.

Support Ash Tree Research

Supporting ash tree research and conservation efforts is essential for finding long-term solutions to combat ash borers. By donating to organizations dedicated to saving ash trees, participating in citizen science projects, or volunteering your time, you can contribute to the preservation of these valuable tree species.

Spread Awareness

Finally, spreading awareness about ash borers and their devastating effects is crucial for saving ash trees. Share information about ash borer prevention and treatment with your neighbors, community groups, and local authorities. The more people who are educated about the issue, the better chance we have of protecting our ash trees.


With the right preventive measures, early detection, and prompt action, it is possible to save ash trees from ash borers in 2023. By staying vigilant and implementing the strategies mentioned above, you can help preserve these beautiful trees for future generations to enjoy.
