I live in Hawaii and if this was here we would either trap the area or run dogs through it. With a little hunting pressure you'll find the pigs will almost completely desert your property. You say there werent any hogs in the area until recently. You better be ready for a whole lot of those things in a few years.

If you set up a big corral style trap you could catch all 7 in one go, then throw them into a pen and fatten them up. Wait for the babies to get about 50-60lbs for the bbq, boar is still quality meat if it's prepared correctly. Pulled pork style sandwiches are great. Here's a great recipe for all you guys to try...It's called Kalua pork. This is the lazy man's way of making an imu and burying the whole pig with banana stalks and ti leaf wrapping it on red hot lava rocks. Get a covered pan, throw chunks of pork and put a few cups of water in. Add 2 or 3 capfuls of liquid smoke and whatever else you want I usually just cook it like this. I've added pineapple chunks before and had good luck. Cook at about 300-350 for as long as possible...about 5-6 hours is a good time. You may have to add water once or twice.

Another option is put bait in front of your stand and get them with bow and arrow. They usually dont spook from the shot too bad. Get the sow first.
