Answer: You've probably encountered some dead worms. They're abundant in soil that's healthy, and they wander about during and after rains or when you've watered your garden. The worms slide around on a thin film of water when they leave the soil. When that water dries up, they're marooned, and often dehydrate. Worms are good guys; they aerate the soil and help decompose organic matter. Don't intentionally kill them!
