If You Have Healthy Ash Trees
They are worth saving! Here is where you need to start:
- If you live in Southeastern Platte County or the Southwestern corner of Clay County or northern Wyandotte County, you may need to begin treatment of your Ash trees next spring.
- Other regions of Greater Kansas City are not under immediate threat but should be on the watch for any spread of this bug.
How to Identify this Pest
It is smaller than many people envision. Note the scale in this photo from the Missouri Department of Conservation:
Treating Ash trees requires chemicals that are toxic to various components of our environment so must be used with care, following all labels. The chemical benefits outweigh the detriment when used appropriately. An effective organic treatment may become available in 2013.
- If your Ash tree is smaller than 18 inches in diameter you may be able to treat it yourself.
- If your Ash tree is 18 inches or larger in diameter, y ou should hire a professional arborist for proper treatment.

Doing Nothing is NOT an Option
A dead Ash tree is a major liability. The wood becomes very brittle quickly and can fall at random, creating a risk of injuring people and destroying property. Extinction of the Ash tree will affect more than 400 species of insects that rely on these trees. Most are beneficial insects and pollinators that form a foundation of the local web of life--primarily as a food source for baby songbirds.
