What is the best method to trap brittle worms ?

[Lampshade]

I never had a problem with them until this week, i found a near 1 foot long giant in my refugium. They don't eat macro algae.... so he's eating my pods! or well, the dead ones at least. I'd set up a crab trab before in my DT with just a coffee cup with a shrimp in it, ended up with a big crab... and 5-6 bristle worms. So I've just put that in the refugium, lets see what i get :S
