Some peckers have drilled small holes in some of my trees. They are shallow holes about 1/8 to 1/4 inch deep but they are oozing sap profusely.
They enrage me to a substantial degree!
Is there any effective way to plug them and stop the sap from flowing?
I used some silicone over them one year and actually seemed to get some positive results, but I am looking for alternative options.
Thanks
