The diesle is more of a trapers trick. It keeps the deer out of the traps. Hogs dont perticularly like diesle, but will eat the corn anyway, where as a deer will not touch it with deisel on it. Like I said, the whole dielse trick is to keep the deer out of hog trapes, or to keep the deer from eating all the corn. The hole trick I mentioned does the same thing with out tanting the corn. The deer can not dig like the hogs, so you dont have to worry about them eating all the corn.
