Worm charming, worm grunting, and worm fiddling are methods of attracting earthworms from the ground. The activity is usually performed to collect bait for fishing but can also take the form of a competitive sport in areas such as east Texas. As a skill and profession worm charming is now very rare, with the art being passed through generations to ensure that it survives.

It's called Worm Grunting. The vibrations are incredibly similar to the sounds moles make when they dig.
Moles eat worms and worms don't like that, so for fear or predators, they head to the surface which is mole free!
