This is no earthworm. These are high-energy worms that quickly eat paper, coffee grounds, leaves, stale bread, grass clippings and more. They are such heavy eaters that if you put them in your garden, they would likely starve.
With a bit of work and simple materials, you can keep a bin of Red Wrigglers in your basement all winter. Feed them your kitchen vegetable waste and shredded paper and watch them convert it all to worm castings, an ideal soil for potting or greenhouse.
(Caution - never feed grass clippings that have been sprayed with herbicide or pesticide, it will kill every last worm)
