Flatheaded Wood Borers

Hosts: Most hardwood trees.
Symptoms: Pecan and other trees that are weak, recently transplanted, young or damaged by sun scald, freeze or mechanical injury are usually attacked. Evidence of larval feeding includes frass or excrement that has been pushed out and dark depressed areas of bark. These dark areas may appear wet or greasy and have a white frothy sap oozing from cracks.
