Bait for catching a Mantis Shrimp?

[uel]

I have atrap and have tried shrimp, brine shrimp, plankton cube, silversides, and have had no luck. I leave the trap in 24/7, so it will get used to it and change the bait every couple of days(during the day) and I place it as close as possible to the last sighting. Has anyone had any success with a trap and if so what did you use to bring him in? Thanks in advance.

I don't have a bait. But I got rid of two one inch long mantis shrimp in my tank. One of them would swim from rock to rock and I just netted it but I know that was lucky. The second one hung out in a small hole in the live rock so I took a drill bit and reemed out the hole while he was in it. This was after they killed 7 or 8 scarlet reef crabs and drove me nuts with that cracking sound they make.
