I freeze lug every year for winter time. Most people gut the worms first, I never bother. Just lay them out in a cool, dark place to dry out on newspaper for 24 hrs then take a dry sheet of newspaper, place a worm on, fold the paper over and so on. You should get around ten worms in a wrap. They defrost fairly well although I would recommend you use a pennel rig to stop the worm sliding down the shank of the hook and masking the point as they will be fairly soft. Forgot to say the worms I freeze tend to be big ones not sure if that matters but it works for me.
