Ive got canines in , dipped traps, dyed traps, dyed & waxed traps, also traps that were just thrown in creek ( creek came from tannic acid waters from cedar swamp). They all work and it would depend on how you trapped with them concerning how you handled them after whatever treating and your trap set methods and luring techniques. I prefer boiling traps and then waxing as traps become a fast tuned piece of equipment if set up properly.
