Emerald Ash Borer (EAB) has been wreaking havoc on ash trees across the country for years. As a tree owner, it’s essential to take action to protect your valuable ash trees from this destructive pest. Thankfully, there are several effective treatment products available in 2023 that can help safeguard your trees. In this article, we will explore some of the top EAB treatment options and how they can help you combat this invasive insect.

The Threat of Emerald Ash Borer

Emerald Ash Borer, an invasive beetle from Asia, has caused the death of millions of ash trees in the United States. These small, metallic green beetles lay their eggs on the bark of ash trees, and once hatched, the larvae burrow into the tree, cutting off its water and nutrient supply. This ultimately leads to the tree’s death if left untreated.

1. Insecticide Treatments

One of the most common and effective ways to control EAB is through insecticide treatments. These treatments can be applied to the soil around the base of the tree or injected directly into the trunk. Soil treatments are typically done in early spring, while trunk injections can be performed at any time of the year.

When choosing an insecticide, it’s crucial to select one that is specifically formulated for EAB control. Look for products containing active ingredients such as imidacloprid, dinotefuran, or emamectin benzoate. These insecticides work by either killing the beetles upon contact or preventing their larvae from feeding on the tree’s tissues.

2. Biological Control

Biological control involves introducing natural enemies of the EAB, such as parasitic wasps, to control its population. These wasps lay their eggs inside the EAB larvae, eventually killing them. While biological control can be effective, it may take several years for the wasp population to build up and have a noticeable impact on EAB populations.

3. Tree Health Measures

Keeping your ash trees healthy and well-maintained is also crucial in preventing EAB infestations. Regular pruning, fertilizing, and watering can help improve the tree’s overall health and make it more resistant to EAB attacks. Additionally, removing dead or dying ash trees from your property can help reduce the attractiveness of your landscape to EAB.

Choosing the Right Treatment

When deciding on the best treatment option for your ash trees, it’s essential to consider various factors, including the size and condition of the tree, the severity of the infestation, and your budget. Consulting with a certified arborist or tree care professional is highly recommended, as they can assess your trees’ specific needs and recommend the most appropriate treatment.

Remember that early detection and treatment are key to saving your ash trees from the devastating effects of EAB. Regular monitoring for signs of infestation, such as D-shaped exit holes, thinning canopy, and increased woodpecker activity, can help you identify the problem early on.


Emerald Ash Borer continues to pose a significant threat to ash trees across the country. However, with the right treatment products and proactive measures, you can protect your valuable trees and enjoy their beauty for years to come. Whether you opt for insecticide treatments, biological control, or a combination of both, taking action against EAB is essential in preserving ash tree populations and maintaining the health of our urban forests in 2023 and beyond.
