North Texas is the cross roads of borers, it is borerville. As adults we find them as beetles, moths, weevils, and wasps. For every part of the plant there is a borer that mother nature has made to feed on. So it is generally not a good sign when you can actually go out to your trees and pick these critters right off your tree. At the time of adulthood these critters are generally looking for trouble, meaning their looking for mates and a place to stay(your tree). Exit holes mean they have already done there damage and can either return or look for a more suitable place, possibly less crowded. Bleeding is an indication that there active, eating machines, the tree responds by trying to pitch it out. Sometimes successful, most of the time not. But there is help and the new chemistry out there is very effective. With cultural care, treatment we can save and recover tree health.
