Emerald Ash Borer TREATMENT

Williams & Associates can protect your valuable ash trees from Emerald Ash Borer (EAB) infestation through the professional application of a safe pesticide. Treating woodland ash can be expensive, but important yard and amenity trees can be protected effectively.

The cost of treatment for individual trees ranges from $50 to $1,000, depending on tree diameter and severity of infestation, with savings available for multiple trees in the same location. For important ash trees, treatment can be a much better and more economical choice than removal.

Controlling EAB is difficult because the lethal damage is done by larvae tunneling around under the bark, where they’re hard to reach. Treatment requires injecting a pesticide into the trunk, where it circulates throughout the tree. This kills the larvae and prevents significant damage for about two years.
