You could make a hog repellent from two slices of bread (one with a layer of mayo, the other with mustard) and some bits of lettuce. Swine fear bread because they know that it makes them yummy. Fried eggs and hash browns also make a good repellent as well as pineapple slices and syrup. Beware of apples, especially Macintosh, as hogs are attracted to them like moths to a flame. Better to have a bigger apple like a red delicious which is too big for hogs to swallow and get stuck in their mouths, thus disarming them.
