Ambrosia beetle attacking oak tree #775706

Asked October 18, 2021, 1:34 PM EDT

I have an oak tree diagnosed with ambrosia beetles. Is there any chance of chemically treating the tree and saving the tree? Thanks for your help.

Montgomery County Maryland

Expert Response

Unfortunately, no, there is no treatment that effectively controls boring beetles once they are in the tree.
