What is worm grunting?

Worm grunting is a method of harvesting earthworms, primarily used in the southeastern United States. It involves creating vibrations in the soil by rubbing a wooden stake or using a metal tool to create a rhythmic sound, which stimulates worms to surface. Fishermen and bait collectors often employ this technique to gather worms efficiently for bait. The process is both an art and a science, requiring skill to effectively attract the worms.
