contrary to what someone might have told you tad,,there are very few concoctions that are potent enough to put a hog to sleep. Rompum will not touch them,ketaset doesnt work and neither does ace. then you also have the problem of getting a needle long enough to penetrate their fat layer. The only reason i comment on this is because i tried it 10 years ago. But the state of texas also throws up to a 10.000 fine on the transportation of live feral hogs. dont get me wrong,,,,it happens everyday but with traps, not dart guns
