Emerald Ash Borer Control

The Emerald Ash Borer (EAB) is an invasive beetle species in the United States which attacks and devastates native ash trees. EAB is native to Asia and was introduced into the United States in 2002 and has since destroyed millions of Ash trees in fifteen states from Michigan to Missouri. To date EAB has been found in 4 Kansas counties (Douglas, Leavenworth, Jefferson, Johnson, and Wyandotte County) but the insects may move to other countries (including the Topeka and Emporia areas) and establish before they are noticed.

The Emerald Ash Borer will attack all species of Ash trees, except the Mountain Ash.

The symptoms of the Emerald Ash Borer include:

  • Canopy or crown decline starting from the top of the tree down
  • Shoots or sprouts growing from trunk or roots
  • Splits in the bark
  • D-shaped exit holes
  • S-shaped serpentine galleries (visible only beneath the bark)
  • Increased woodpecker activity

EAB symptoms can be confused with native ash borers. To know the difference click here.

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. 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.

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.
