The Emerald Ash Borer (EAB) has become one of the most devastating pests for ash trees across the Midwest—and Kansas and Missouri are no exception. If you have ash trees in your yard, knowing the signs of infestation and acting early can make all the difference between saving a cherished tree or losing it.
At Martz Bros Tree and Lawn Care, we’re here to help you stay one step ahead.
What is the Emerald Ash Borer?
The Emerald Ash Borer (EAB) is an invasive beetle that primarily targets ash trees. The real damage happens during the larval stage, when the larvae burrow under the bark and feed on the tree’s vascular system.
This feeding disrupts the tree’s ability to move water and nutrients, causing stress, decline, and ultimately, tree death.
Ash trees most at risk in Kansas and Missouri:
- Green ash
- White ash
- Black ash
- Blue ash
How EAB Spreads
EAB doesn’t travel far on its own. Its spread is mainly caused by the movement of infested firewood, nursery stock, and other ash products. Once introduced to an area, the beetles multiply quickly, attacking healthy and stressed trees alike.
Tip: Never move firewood from one location to another. Always buy and burn local firewood to prevent accidental spread.
Signs of EAB Infestation
Keep a close eye on your ash trees for these early warning signs:
- D-shaped exit holes in the bark from adult beetles emerging
- S-shaped tunnels under the bark created by feeding larvae
- Thinning canopy and premature yellowing or browning of leaves
- Vertical bark splits revealing larval galleries underneath
- Dead branches starting at the top of the tree and working downward
Without early treatment, infested ash trees often die within 2–4 years.
How to Protect Your Trees
Early intervention is key. Homeowners have several options to protect their ash trees:
Preventative Insecticide Treatments:
- Trunk injections or soil drenches can protect healthy trees if applied before heavy infestation.
- Treatment is most effective in the spring or early summer, when the beetles are active.
Monitoring and Regular Inspections:
- Annual health assessments by a certified arborist help detect problems early.
Removal of Severely Infested Trees:
- If a tree is too heavily damaged, safe removal prevents the spread to nearby ash trees.
