Emerald Ash Borer (EAB)

The emerald ash borer (EAB) is an invasive insect that is devastating ash trees across the Midwest. It has been found in Douglas, Jefferson, Johnson, Leavenworth, and Wyandotte counties. We suspect that EAB is in Topeka and possibly in Emporia but the populations are not large enough to have been detected yet. If an ash tree is left untreated in an area if heavy infestation it will die since the tree has no natural defense against this insect.

Preventative Maintenance Offers the Best Protection:

Wellnitz Tree Care offers a line of systemic insecticide applications to treat or prevent not only EAB but also native ash borers. We do soil injections for preventative measures because they are effective and are non-invasive to the tree. The soil injection is be best option as far as affordability and there is no drilling into the tree, however if EAB is already present we can inject directly into the trunk for quicker results. We can also remove trees that have become too heavily infested to save. Please visit our contact us page to set up an appointment and one of our certified arborists can discuss possible treatment options.

Stop the spread

EAB is spread through the transport of infested firewood. Firewood should never be transported more than 50 miles and 10 or less is best. Wood should be burned where it was purchased or harvested.
