If you put something sweet out I dont think they will eat it! this picture is a hog rubbing on some molasses i poured on a cresote log. I have hundreds of pictures looking over 3 traps and never have I seen them eat anything sweet! I have put diesel on corn but just to keep deer out of it I dont think it works any better! The thing that worked best for me is bury a five gallon bucket flush with the ground pour it half full of corn then pour two-three cans of cheep beer in and half a bottle of apple cider then 1 gallon water FROM STOCK TANK OR CREEK NOT TAP WATER! They love the beer! after all its fermented grain.
