Short Answer
Ash tree borers are a type of beetle that infest ash trees.
They bore into the bark of the tree, tunneling through the inner bark and cambium layer to create galleries that disrupt the flow of nutrients and water.
The larvae feed on the wood, which can weaken and eventually kill the tree.
Ash tree borers can be identified by the presence of oval-shaped exit holes and sawdust-like frass around the base of the tree.
What is the Ash Tree Borer?
The ash tree borer is a type of beetle that is native to North America and can cause significant damage to trees of the Fraxinus genus.
It is typically a metallic green-bronze in color and measures about 1/2 inch in length.
The larvae of the beetle can cause even more damage to ash trees as they feed on the innermost parts of the tree.
The ash tree borer feeds on the inner bark of ash trees, which can lead to tree death if left untreated.
The larvae are more destructive to ash trees than the adults because they feed on the innermost bark of the tree, which can cause significant damage to the trees vascular tissues that are essential for the trees survival.
It is important to keep an eye out for the signs of ash tree borer infestation, which can include: holes in the bark, sawdust-like frass (the excrement of the beetle), or galleries (tunnels) in the inner bark of the tree. If you suspect an ash tree borer infestation, it is important to act quickly to prevent further damage to the tree. Treatment of ash trees affected by the ash tree borer typically involves the injection of an insecticide into the tree’s trunk, which will help to kill off the larvae and adults and protect the tree from further damage.
What Does the Ash Tree Borer Look Like?
The ash tree borer is a metallic green-bronze beetle, about 1/2 inch in length.
It is native to North America and is responsible for causing significant damage to trees of the Fraxinus genus.
It can be difficult to spot due to its small size, but there are certain characteristics that can help you identify it.
The beetle has a shiny, metallic green-bronze body with black or brown spots on its wings.
Its head is large and oval-shaped, and its legs are short and stubby.
It also has a distinctive curved antennae and six-legged larvae.
The larvae of the beetle are especially destructive, as they feed on the innermost parts of the tree.
The larvae can cause even more damage to ash trees as they feed on the inner bark and sapwood.
When the larvae are fully grown, they will pupate and emerge as adult beetles.
What Damage Does the Ash Tree Borer Cause?

The larvae of the beetle can cause even more damage to ash trees as they feed on the innermost parts of the tree.
The ash tree borer is a metallic green-bronze beetle that is about 1/2 inch in length.
The larvae are cream-colored and cylindrical in shape.
They feed on the inner bark of the tree, which disrupts the flow of nutrients and water, ultimately leading to the death of the tree.
The adults are active from late spring to early fall and lay eggs on the bark of the tree.
The damage caused by the ash tree borer can range from minor to severe.
In its early stages, the beetle can cause leaf discoloration and thinning of the canopy.
As the beetle progresses, it can cause larger branches to die off and bark to be pushed off the trunk.
In the most severe cases, the entire tree can die.
The ash tree borer can also spread to nearby trees, making it difficult to control.
Once the beetle has infested a tree, it can spread to other nearby ash trees, leading to a larger infestation.
Treatment of ash trees affected by the ash tree borer typically involves the injection of an insecticide into the tree’s trunk.
This insecticide will kill the larvae and adult beetles, preventing further damage to the tree.
It’s important to note that while this treatment may help save your tree, it’s not a guarantee that it will survive.
Once the beetle has caused significant damage, it may be too late to save the tree.
In addition to treatment with insecticides, there are also some preventative measures you can take to help protect your ash trees from the ash tree borer.
Pruning dead or dying branches can help reduce the likelihood of an infestation, as can planting resistant species of trees near your ash trees.
The ash tree borer is a destructive pest that can cause significant damage to ash trees if left untreated.
Knowing the signs of an infestation and taking preventative measures can help save your tree from falling victim to this destructive beetle.
If you think your ash tree is infested, contact a professional tree care service immediately to assess the situation and determine the best course of action.
Where Can the Ash Tree Borer be Found?
The ash tree borer is native to North America and can be found in many different parts of the continent.
It can be found in the eastern United States and Canada, stretching from the northern parts of New England and into the southern parts of Florida.
It is also found in the western United States, from California to Texas.
The ash tree borer can also be found in Central America and parts of Mexico.
The ash tree borer prefers to live in moist, shady areas such as forests, woodlands, and areas with lots of ash trees.
It can also be found in urban areas such as parks and gardens with ash trees.
It typically lays its eggs in cracks in the bark of the ash tree, and the larvae feed on the inner bark.
This activity can cause significant damage to the ash tree if left untreated.
How Can Ash Trees be Protected from the Ash Tree Borer?
The best way to protect ash trees from the ash tree borer is to prevent them from infesting the tree in the first place.
The most effective way to do this is to keep the tree healthy and vigorous.
Proper watering, pruning, and fertilization are key to maintaining a healthy tree.
Additionally, removing dead limbs and dead wood from the tree can help to reduce the risk of infestation.
Inspecting the tree for signs of infestation is also important.
The ash tree borer can be identified by its metallic green-bronze color and its 1/2 inch size.
The larvae of the beetle may also be visible in the form of tunnels in the bark of the tree.
If the tree does become infested, it is important to take action quickly to prevent further damage.
The most common treatment for ash trees affected by the ash tree borer is the injection of an insecticide directly into the tree’s trunk.
This method is the most effective way to ensure the insecticide reaches the larvae of the beetle and kills them.
There are also insecticides available in liquid form that can be sprayed directly onto the tree.
However, this method is not as effective as the injection method since the insecticide may not reach the larvae if they are deep in the bark.
It is important to remember that treating a tree for the ash tree borer is not an easy task.
It is important to seek professional advice from a qualified arborist or certified tree care specialist to ensure that the treatment is applied properly and is effective.
This is especially true if the tree is severely infested or is in a delicate condition.
If the tree is not properly treated, it could be at risk of dying.
Are There Any Natural Predators of the Ash Tree Borer?
Yes, there are natural predators of the ash tree borer, though the effectiveness of these predators in controlling the ash tree borer population is not well-known.
The most notable natural predator of the ash tree borer is the parasitoid wasp, which lays its eggs inside the larvae of the beetle.
When the eggs hatch, the wasp larvae feed on the beetle larvae, which helps to reduce the population of ash tree borers.
Other natural predators include ground beetles, spiders, and woodpeckers, all of which are known to feed on the larvae and adult ash tree borers.
In addition to natural predators, some chemical insecticides have been shown to effectively control ash tree borer populations.
Injecting insecticides directly into the tree trunk is the most effective way to treat ash trees affected by the ash tree borer.
The use of chemical insecticides should be done under the supervision of a certified arborist, as improper use of these chemicals can cause damage to the tree.
Are There Any Chemical Treatments for the Ash Tree Borer?
When it comes to treating an ash tree infested with ash tree borer, one of the most effective methods is to inject an insecticide directly into the trees trunk.
This method is ideal as the insecticide can penetrate deep into the tree, targeting the larvae of the ash tree borer.
In some cases, an insecticide can be applied to the bark of the tree to help kill adult ash tree borers.
However, this method is less reliable as the insecticide can be washed away by rain or other precipitation.
In general, the best way to treat an ash tree infested with ash tree borers is to contact a professional arborist to assess the situation and determine the best course of action.
An arborist will be able to determine the severity of the infestation and provide advice on the most effective chemical treatments.
In some cases, the arborist may suggest removing the affected tree entirely to prevent the spread of the ash tree borer to other trees.
When selecting an insecticide, it is important to choose one that is specifically designed to target the ash tree borer.
Many commercially available insecticides contain a combination of chemicals that can be harmful to other beneficial insects or animals.
Therefore, it is important to read the instructions on the packaging carefully and follow all safety precautions.
In order to prevent an infestation of ash tree borers, it is important to practice proper tree care.
This includes regular pruning, watering, and fertilizing.
Additionally, it is important to regularly inspect ash trees for signs of infestation, such as sawdust or holes in the bark.
If an infestation is found, it is important to act quickly and contact a professional arborist.
