Emerald ash borer

Ash Wood Utilization Options for Homeowners

Emerald ash borer (EAB) poses a serious threat to ash trees in both communities and residential landscapes, killing 80% of ash trees in infested regions within 10 years of its discovery. In communities, standing dead and dying trees will pose a threat to people and property. Unless a homeowner is dedicated to treating their tree long into the future, most ash trees will die and need to be removed.

Emerald Ash Borer Look-Alikes

There are many bright metallic-green insects in Nebraska, but the emerald ash borer beetle is only a half-inch long and strictly associated with ash trees. Use the chart to help determine if EAB is present on your property. 

Pros and Cons of EAB Treatment

Regardless of the decision made, trees should not be left standing until they are dead or have significant dieback. Ash trees killed by EAB become brittle quickly and could start to fall in as little as a year. Additionally, these trees pose increased risks for workers and will likely result in much higher prices for removal. Once EAB is found within 15 miles the decision should be made to treat or remove. Preemptive removal and replanting before this time is also an option.

Soil Treatments Emerald Ash Borer: Information for Homeowners

Soil treatments are applied to the soil around the base of a tree. The chemical is picked up by the roots, carried up the trunk, and distributed throughout the plant, providing protection from pests feeding on the tree. Soil treatments can be effective in controlling emerald ash borer (EAB), a destructive pest of ash trees.
