Diesel will attract hogs. Some people soak a piece of carpet in diesel and hang it a foot of the ground. Hogs like to rub on it to help with the tick problem.. Now I've never done this, just have heard of others doing it.

If diesel works that good, I was thinking of spraying in on my boots as a cover scent. Just a thought. I have used vanilla for dear, wonder if that would work on pigs? May try it next time.
