I was told by the county extension in white county, that I needed to use moth balls around the peach trees for peach tree borer, is this what yall use, I have sap running out of my peach trees, this may be old, I'm sure their all dormant now, but none the less I have to take care of this problem, soon.
Howdy kathy ann...now is not the time to use moth balls (if ever). I don't know where you are, nor your zone, but perhaps you are into Winter weather now?
What you could do now is cultivate around the base of the trunk, exposing the grubs that may be wintering over. If you're lucky you'll find some! Other grubs/larvae will be in the trunk, usually within a foot of the ground. Stick a wire (coat hanger) into the burrows and smash whatever is in there. If you have other fruit trees nearby (plum, cherry, etc) you may want to check them out also.
