As someone mentioned,trap need's to be large enough for at least a dozen and preferablly more. Otherwise they wise up and avoid traps. If landowners would cooperate the population can be controlled but too many people operate with greed and stuborness as primary to common good.
If all landowners inside natural boundaries (rivers,IH Hi-ways,lakes,towns ect) form a commity and contribute $1 for each acre they own to a fund and each do thier part ongoing,the success is far better while expense and labor is far less than each doing their own thing. Let's say 100 square miles lie inside natural boundries. You have $64k to build 10 corral size PORTABLE and 10 semi-portable traps, a high tech device that alow's dropping door on trap from 50 miles away via smart phone,half dozen recorder type trail cams,1 live data via smart phone trail cam to inhance remote control for gate,a custom trailer to move traps,rifle,ir rifle scope,a silincer if someone can quilfy, a low flatbed with winch to move dead hogs and occasionally buy corn(supermarket spoilage should be mor than adiquate for bait). According to # of landowners,a suitable group messaging is set up. Hogs run in gangs,packs,herds,more accuratly called sounders. About the time you think hogs have disappeared or decided they don't like your land,a herd root's up 10 acres of field and your orchard in a single night. Unles you have been vigilant with baiting and tending traps for 3 months that aren't catching this would ordinarally be the time you set traps and already wasted a day. The hogs will be in the general area and drifting but unless field was planted in something they like or orchard has lots of fruit on ground,the hogs aren't likly to return to the same place for 4 weeks to 4 months. Here's where you start saving time and expense. You notify group message of location, date,time,type damage,aproximated acres and number of hogs. Rarly will 24 hours pass without reported sightings and/or damage. Reports establish how many sounders are on the 64k acres,size of sounder A-B&C,predictable direction of travel for each sounder and of course how many have gone to big pen in the sky. Traps begin baiting for anticipated arrival. Doors are open and blocked to prevent triggering on some traps based on collective trail cam history. Needless to say,the wi-fi door is moved for best use. If the situation warrant's ,you have the stomach and guys with skill,boars large as can be safly handled get free vasectomies and tips of their ears cut off. Hogs grow rapidly so there's no need to go after the largest around. The tipped ears prevent them being shot when traped. It is also understood anyone showing off a trophy with tipped ears might be subject to something unpleasant.
