Tell me how please

Please oh please tell me how to get rid of this CBS I have short of taking apart the tank?
I've tried traps and caught everything EXCEPT the CBS - he's a crafty *&^##@!
Any suggestions?
All help appreciated.

What size tank?
Is the Shrimp motivated by food?

Nope, not motivated by food- stays behind the rocks all day - will come out at night, but the first thing coming close in the water it hides again. Like I said....traps not working, I catch everything but him. I want him out! And I'm almost to the point of tearing my rocks up to get him.....almost - not quite tho. Just open to suggestions - any and all!
