Worm grunting is the practice of driving wooden stakes into the ground and rubbing the top of the stake to generate a grunting sound, that drives worms to the surface where they can be collected for fishing bait. It is believed that the worms surface in an attempt to avoid being eaten because the vibrations are similar to those produced by digging moles, which prey on earthworms.
