Ash Tree Bark

Asked June 4, 2019, 7:52 PM EDT

Large chunks of bark are peeling from the tree and wondering if you might have ideas. Have treated for the ash bore beetle pretty regularly and as recently as last summer. Found what might be insects under the bark that peeled away (see pictures). Thanks!

HI there,

Please find below a fact sheet detailing the wood boring insects of ash trees. This should hep you identify what is on your trees. Jefferson County Extension also offers a diagnostic lab where you can bring in the insects and we can identify them in our lab
