hm.. you probably should identify the worm first.. bobbit, fire, or bristle..
if its a bobbit, den you probably should rescape.. they're too fast to catch..
if its a fire or bristle, you could sneak up on them in the middle of the night, and hopefully get a good grip (using tongs) and pull it out.. but i would expect it to break into 2.. therefore leaving probably another 1ft inside.. u need to catch it again.. but it might just work.. because they're slower and less sensitive than bobbits..
just my opinion, good luck..
