Thats why I asked if anyone had tried it. That thought did occur to me, but then again the chances of the snakes tail being "caught" by the trap and held in long enough for it to do anything is like one in a million. Seriously. I'm pretty sure the snake would notice something clamping down on it's tail. =p
Ok, so chances are one in a million. Is it worth it to you? Not worth it to me. Why put something in there if there is even the SLIGHTEST possibility of it being harmful?
