I seen it in another topic here & thought I would explain it..Or at least how I do them. I use a landscape timber or a 4x4. I make it 4 or 5 foot tall. I dig a hole a I try to get them about 18" to 2 foot.. I quick crete the post in the ground. I use burlap sacks, but you can use that brown rope. I forgot what its called. I tie the sack vertically to the post with bailing wire. Now days I use store bought products. Soak the sack with it & they will rub it dry. I know people that use railroad ties or telephone poles the hogs like the creosote that they are treated with. I have always been under the impression that the hogs use the chemicals on the sack for bug control..I am not sure though.
