We have tried them all......push door, figure 6, trap door, etc. Without a doubt, the best trap for us has been the guillotine-style door with a big pen made from hog panels. Not just a little 4' x 7' trap. The ability to catch 10-15 hogs at a time is huge. You can damn near get the whole group almost every time. Only downside is that it isn't portable. Our pens are approximately 12' x 15'. We've got two of them and have caught 8+ hogs multiple times. Can't even begin to tell you how many times we have caught 3-5. You aren't going to even put a dent in the hog population just catching 1-2 at a time.
On the push door, the little hogs tend to not be able to push it, so you miss out on those a lot, if they don't get in prior to the door closing the first time. That being said, we have caught 3-6 pigs in this style of trap many times. They are nice because you can drag them around with an ATV to wherever they are hanging out. If you get to where they are, your chances of catching them go up exponentially.
