wasps eating bark of crepe myrtle
We live in eastern TN and for the first time this yr we have these wasps that are about 1 1/2 to 2 inches long. I have 3 myrtles that are 2 yrs old and have now discovered the wasps are stripping off the bark of the trees. The tops of the trees look like they are dying. What can be done to save our trees? Thank you.
I would treat with Neem OIl.
Here are a few links for you.
