Look atthe utility poles in areas where there are lots of hogs: Hogs rub on those poles because of the creosote,ittakes care ofsome of their bugs. Takea piece of carpet and wrap it around a tree with the back side out. Drive the nails in as far as you can to hold it in place.Soak that carpet with used motor oil and some cheap insecticide. The hogs will rub on it,love it and keep coming back.
