"Super Red Worms" (aka European Nightcrawlers) are excellent for fishing, gardens, outdoor compost piles, and promoting healthy lawns and garden soils.  They grow to the length of 4-5 inches long when mature, and are very active.  They are hearty worms, very effective at aeration and fertilization of the soil. The tunnels they burrow allow water and other nutrients to reach root systems of your lawn and gardens. Proper aeration of soil guarantees excellent root growth and strength. Chickens love them too!
