Emerald ash borer is a beetle that invaded the U.S. in the early 2000s. Some believe it started in the 1990s in Michigan when wood from Japan was infected by this ash-tree-killing pest. The EAB larva bores through the bark of the ash tree and makes its home in the tissue beneath the bark. When it matures, it bores through to reproduce and lay more larva on other ash trees.
The bad news is that despite the forest services’ efforts to eradicate the emerald ash borer, it looks like it is here to stay. The good news is that there is an effective ash tree borer treatment, which can save your trees.
Ash Tree Disease Treatment
The first step in ash tree protection is to identify the stage of damage. If the tree doesn’t have to be removed, we’ll provide protection to prevent ash tree bark from falling off. Warner’s insecticide application gives your tree the protection it needs to defend itself against this invasive pest. Our technicians use the soil drench method for applying the insecticide, thus avoiding injury to the tree caused by injections. All products used are environmentally safe for treating damage on ash trees from EAB and other common tree insects creating infestations.
Ash Tree Treatment Cost
Do it yourself insecticides can range from $20-$50 per treatment. When hiring a professional arborist from Warner’s the cost depends on the size and location of the tree along with the application method and type of insecticide used. If you notice signs of EAB infestation, be sure to contact Warners as soon as possible to ensure we can save your Ash tree ontime and avoid having to remove the tree completely.
Identifying Ash Tree Disease & Damage
The full cycle of the emerald beetle will cause damage at every stage. The larvae can get under the bark of your ash trees and disrupt the upward flow of water, thus damaging the ash trees on your property. You’ll begin to notice bark splitting and thinning in the upper portion of the tree. Woodpeckers are attracted to the larvae so if you notice damage that will be a sign of an infected ash tree from EAB. Contact Warner’s for proper identification and investigation for treatment or removal.

Besides the environmental benefits, properly cared for ash trees can increase your property value. Given the damage that emerald ash borers can cause, it is best to protect your ash trees as early in the growing season as possible. The city of Minneapolis Tree Ordinance PB 10-23 allows for a private tree inspection to search for any disease or infestations.
