What is the Emerald Ash Borer? 

The emerald ash borer is a species of insect native to Asia that has been increasingly impacting the health of North American ash trees in recent years. As the name suggests, this insect has a green body covered with delicate black spikes, and it can live for up to 5 years without feeding or reproducing.

When these insects attack a tree, they lay eggs inside the bark and begin to feed on the soft tissue under the tree’s bark. As they feed, they cause irreversible damage to the tree’s structure and make it difficult for it to maintain itself. This issue can lead to a decline in the tree’s health and eventually death. 

What Are the Signs of an Emerald Ash Borer Invasion? 

The signs of an emerald ash borer invasion are easy to spot if you know what you’re seeking. Because of the way they attack trees, the primary symptom of an emerald ash borer infestation is an outbreak of dead branches on a tree’s trunk and branches. However, other pests can also cause similar symptoms, so it’s crucial to know the specifics.

 In some cases, the damage caused by the emerald ash borer is minor and only in the tree’s outermost branches, but this usually means that the bug has not yet made its entrance into the tree and is planning to attack later. However, suppose the infestation has progressed far enough that the dead branches persist throughout multiple tree layers. In that case, it’s more likely to be a severe infestation, and you should take steps to deal with it as soon as possible. 

Another sign of an ash borer invasion is the presence of “D-shaped” holes in the tree’s bark. The adult beetles cause these holes after they emerge from the tree, searching for new potential ash tree hosts and mating partners. If you see any of these signs in your trees, it’s a good idea to have them checked out by an expert.

Preventing an Invasion

As a homeowner, you can prevent an emerald ash borer invasion by being careful with wood transport. Don’t move firewood off your property, buy only local firewood, and burn all firewood before spring. For extra protection, you can use an insecticide called imidacloprid, which you apply to the soil surrounding trees, typically in spring or fall.
