Fireworms on live rock from KP Aquatics

I'm about 3 months into my tank and have witnessed fireworms munching on some coral. Anyone else run into this that's purchased live rock from Florida ?
If so, were you able to eradicate them ?
I've tried a trap with no luck. Next step is getting either an arrow crab or coral banded shrimp ? Anyone with experience know which would be the better choice ?

which corals were they eating and do you have a pic of the worms?

I'll try to get a picture later. So far i've noticed damage to a couple favia corals.
From what I understand, the fireworms are native to the caribbean and the rock comes from the Fl Keys.
