They hit the high points. If you can bait, find where they are rooting and dig some holes with post hole diggers, as deep as you can. Fill the holes half full of corn, then pour some strawberry Jello ontop of the corn. Top off the hole with corn. Give it a night or two and they will find it. They will root at the holes for about a week. Make sure it is in an area where the farmers will not mind a big hole, because they will dig a trench about 4 feet deep and 6 feet long.
