Ash Borer Treatment

Ash Borer

Ash borers are generally considered an invasive species and they are mainly responsible for killing ash trees, their host tree…

What is ash borer?

The emerald ash borer was first discovered in the Detroit area in 2002. It is believed to have entered the country on wooden packing materials from China. The bright metallic-green beetle may be smaller than a dime, but it is capable of taking down ash trees thousands of times its size. Adults are typically ½ inch long and ⅛ inch wide.

Adults usually emerge in May from infestations to the trees during the previous year. The larvae bore into the ash tree and feed under the bark, leaving tracks visible underneath. The feeding disrupts the tree’s ability to transport water and nutrients, resulting in dieback and bark splitting.

Trees heavily afflicted with emerald ash borer infestation showcase canopy dieback usually starting at the top of the tree. The heavily infested trees usually die within a couple of years after the symptoms of the infestation are first identified. Hence, the prevention and control of the invading species are essential for the proper survival of the trees.

So, what are the tell-tale signs of an emerald ash borer infestation then?

If you witness tree canopy dieback, yellowing and browning of the leaves, especially in the upper 1/3 part of the tree, the tree could be infested.

You can also be certain of an infestation if you see larval galleries in the wood under the bark packed with frass, a mixture of larval excrement and sawdust. If you notice increased woodpecker activity, there could be an infestation too; after all, woodpeckers feed on emerald ash borer larvae and pupae.

Reports indicate that emerald ash borer populations usually bloom and expand through the transportation of infested firewood. Therefore, you shouldn´t move firewood from your property or take it to other areas. If you suspect emerald ash borers infesting your ash trees, you shouldn´t hesitate to ring in the services of a professional pest management service.

Ash borer treatment- How can you get rid of ash borer?

It is rather unfortunate that most native North American ash trees have little or no natural resistance to this pest. Hence, you will need to help your ash trees to ward off the pests. And, you can do this effectively by using insecticides.

Thankfully, there isn´t a dearth of insecticides available for purchase in the market.

The insecticides can effectively help homeowners manage their emerald ash borer issues (for example, Bayer Advanced 12 Month Tree and Shrub Insect Control).

If you intend to protect your ash trees from emerald ash borer, you will be required to treat the ash trees every year. You should also bear in mind that treatments can only be effective if the tree is healthy.


Therefore, it is also equally necessary for you to fertilize and water your trees to promote its well-being and sound health.

When searching for an insecticide, you should particularly look for a product that contains imidacloprid. Such systemic insecticides should be applied around the base of an ash tree as soil drenches. The application of imidacloprid insecticides is much more effective when applied during spring. Although an emerald ash borer treatment can cost quite a lot, it is worth it.
