Key points to remember are that trapping is an important thing to do, but you gotta be careful that you're not just educating more pigs than you're trapping. The best strategy is to trap all the pigs, the entire sounder, at the same time. And if you don't manage to trap them all, then you've got to eliminate the ones that didn't go into the trap, because those just became educated. And while they're educated they're reproducing.
