Hi Carl!
Yes, people have "called nightcrawlers" using metal rods pounded into wet soil. Unfortunately the usual technique requires high voltage and is extremely dangerous. I understand that it takes a fairly hefty current
to irritate the worms, and it takes a dangerously high voltage to
force that current through the dirt. Electrical experts might know
enough about electrical safety to carry this out without dying, but
the rest of us should obtain bait at the sporting goods store.
I remember my grandfather mentioning that it's possible to call
nightcrawlers with sound. I guess this involves pounding a metal
bar into dry soil, then whacking the bar to make a lot of underground
noise. This is worth a try, and nobody has to risk accidental death
by electrocution.
