Bristle Worm Question

[The Guy]

I notice some bristle worms that come out once the lights go out, they seem quite long and about as thick as a garden worm. I tried to grab one with plastic tongs but they seem very strong and he broke off at about an inch long. The rest of it disappeared back into the rocks. I did see traps that are available, do they work or is there a better way to get rid of these creepy things
