redbud with flathead borer

Asked July 29, 2018, 7:59 PM EDT

Hi, My beautiful eastern redbud has poor growth on one side and peeling bark with exit holes here and there. Peeling off some of the bark I find flathead borers (and small ants). The damage to the bark is substantial. Is there a way I can treat it (and perhaps kill the current batch of larvae)? If borers have already gotten in, is the tree a goner? Thanks!

With the damage as extensive as it is to the main trunk of the tree, it is too late to apply any treatment that would be effective. It is our recommendation that you remove and replace the tree.

The Maryland Department of Natural Resources provides a good list of trees to consider and they provide a small rebate for planting native trees.
