ya you need to get ride of them,they dont only destroy your property but also leave many dieses ,i would setup several bait sites and go to town on them,here is a tip for you,build a big ass pen,make it round,put a gillitene door on it,bait it ,and keep baiting it to they feel comfortable,then one day go and pull pin on door were it works and id bet you will catch a sounder of about 20 at the least,start popping and dropping them were they stand,pull up poles and wire move to another section of the farm,they have some really well working traps these day and hogs dont even know there even in it till you spring the doors by remote,but as with every thing cost of them were most folk cant buy them
