Don't k now what other people use but we use sour corn, fill a 5 gal. bucket about 3/4 full with corn then fill with water and set it in the sun and it will get real stinky in a couple of days, we keep about a dozen buckets working all the time, we have 6 traps that we keep working from the end of deer season till deer season starts again.

some days we get 20 pigs others only 2 or 3 , pigs are smart, so we keep moving our traps every few days, look for pig sign set a trap close by, water really helps. remember pigs are predators ,they kill the hell out of fawns, and eat Quail and other nesting birds like candy. when they can't find anything else to eat, they eat each other, catch em and kill em, that's what we do.
