TAMU extension service identifies chlorpyrifos (dursban?) as effective.
Unfortunately, we cannot find any updated information on the red oak borer. We recommend that you call your local cooperative extension office and ask what their recommendations are. Once you have an active ingredient recommendation, we will be happy to help you find the correct product. Chlorpyrifos was banned several years ago and is no longer available.
