I bought a used metal pot, with a cover, years ago for waxing traps. I don't know the actual size but it's about the size of a soccer ball. I originally bought enough trappers wax to fill it 2/3's full. Every year I add a couple of cakes as I wax, to keep it at the 2/3's full mark. Its been about 6 or 8 years on this pot. This past fall, I had more dig ups and flipped traps than normal, with Coyotes. What would contaminate my wax pot? Would the age of the wax have a negative effect? I am trying to determine the reason for the increased dig ups.
