Holes appear in the lower part of the trunk or in the upper trunk and the lower crotches of the plant. Lots of gummy sap oozes from these holes. Sawdust may surround the holes or collect at the base of the tree under the holes. In summer, empty pupa skins may protrude from these holes. During the spring and summer, some leaves and branches may wilt. 1 or 2 borers may be enough to kill young trees.
Apply an insecticide that''s labeled for peachtree borers, following label instructions. Avoid wounding trees.
