A) some kind of trap
B) set down in some kind of water
C) filled with some kind of bait (a.k.a. bologna).
Not walking out into the yard and shining a flashlight down a hole.

I don't know about you but the fact that the crawdads live in the lawn (I assume because the water table is so high there) kind of freaks me out. In the it's okay to visit but I could never live there kind of way.
Sorry Illinois! You are not the state for me.
