Are you in south western Ga. ?? You will never get them if you continue to chase them all over the property. All you are doing is educateing them as to YOUR techniques. IMO you need to make spots for them to come to/congregate.
You need to establish areas that are very carefully considered,that offer the hogs food,water, and some close by shelter. You need timed feeders and roll barrels. Put up some scent posts and frequently add more lure to them. As they are rubbed/scented you can back off on the store bought scent.
These areas need to be chosen for the "normal" wind direction,the sunrise and the moon rise. Carefully consider the distance from your dedicated shooting position to the bait/attractant. Consider the approach to the stand locations. (You don't wanna be shittin' where your fixing to eat.) Do this with consideration to the quality/type of your NVD.
As stated above,take the sows first. Even at night you can pretty much tell the dominant sow(s) by their movements with experience. When the dominant sow gets ready to come,they all come. When she gets ready to leave,they all leave. Go to the farm supply store and get a product called KERSO-D. It comes in a small'ish yellow can. It is black and oily feeling. It is designed to be used as a wipe to keep the biting flies from livestock. It smells exactly like creosote. Put about an ounce to a gallon of water and pour it on the rubbing posts. Use it ONLY on the rubbing posts. You do not want them to associate this smell with humans.
Remember...you gotta kill 70% of the hogs on your property every year JUST to maintain the heard at the present level. Get to it.....and.....good luck. --- pruhdlr
