HehehehWire traps work excellent with this sort of thing. So, what kind of prey are you after? Hm? What're you doing?You can also make an obvious hole to goad someone into jumping into the actual pit.You can also make it so it's remote detonated.Nobody's gonna fall for such an obvious trap.Wha--?!
That oughta do the trick. You've gotta use dirt to camouflage the hole.
