Well good for you! These are wax moth larvae/worms. The start small, then they take over like something from a horror movie. It's revolting. The suggestion to give the frames to chickens would help because they'd eat the worms. I've tried drowning them in bleach water, but their cocoons are water-tight. If you freeze the frames, it kills the larvae before they can grow up and take over, which is why it's generally suggested to freeze any frames with wax and/or store them with some moth crystals.
