Use liquid nitrogen, be ready to work quick. Nitrogen in a styrofoam cup, you need about 2 table spoons, pour into a 3 cc syringe with out the plunger, turn it upside down over the wart. It will evaporate in a few seconds. Use side nippers to cut the wart at skin level. Cold makes it not bleed, not long enough to turn hair white, cold kills pain from nippers, and you are done. The freeze away might work, but does it get cold enough.
You can use feed sack thread, forceps tie it tight around wart, it will fall off in a few days, the bigger the wart, the longer it takes. A big wart may take a second thread in a couple of days.
Just a suggestion.
