Pest 101: Emerald Ash Borers

Sep 6, 2019 | 0 comments

Be on the lookout for emerald ash borers. Your trees will thank you.

In the Ozarks, we are proud of our trees. But a small insect is putting our beautiful ash trees at risk. The emerald ash borer is an invasive pest that will eventually kill unprotected ash trees. Treating your tree early can help save it.

Here are a few signs to know if an emerald ash borer has affected your tree:

  • D-shaped exit holes about 1/8″ wide.
  • Winding, s-shaped tunnels just under the bark.
  • New sprouts on the branches and lower trunk.
  • Increased woodpecker activity on the tree.
  • Sparse leaves and/or branches dying in the upper part of the tree.
