how catch a Mantis in an Established LR wall

[phishschtick]

OK, I thought I'd rid my tank of these creatures. As I was mounting a new frag, I saw the distinguished look of two eyeballs on sticks peering at me. I'm glad he didn't strike. I coaxed it out just a bit with some shrimp, but he quickly retreated. Any trick out there to capture this dude?

Try glass jar trap.

Edit: Sorry they swim.
Need plastic coke bottle cut top off and invert it to make a trap.

i have had one for two years with no noticible evils. he eats a few snails every now and then. i gave up after he kicked my *****. traps,bottles, (THE EXTERMINATER TRAP BAITED A HUNDRED TIMES)ALL I CAUGHT WERE FISH AND CRABS....I HAVE ACCEPTED MY MANTIS AS A WORTHY OPPONENT WHO DEFEATED ME IN BATTLE.

I have a Bird Wrasse, Any crustation that is not lightning fast and can fit 100% in or under something, He snacks on.(but not the cleaner shrimp and I don't know why)
