Great lakes horned worms

For one thing, you can't just drop the earthworm in there and expect it to be snatched up. You need some tongs and you need to wiggle the worm and tease the frog with it. Their instincts usually kick in with moving prey. Try tickling the frog's mouth with the worm.
Good Luck!
