limpers late in tourney

How do you handle limpers with decent but not premium holdings like KJos or AXos. They are probably on draws or mediocre hands, but they could be setting a trap.

I guess it depends on stack size (only 4-5 people in, so you are either in a blind, button or CO). If I have a big stack, I would probably raise and fold to a re-raise. If shorter I will probably just check or lay it down. Just like I don't like to blind steal from bigger stacks.
