Red Wigglers are tough and hardy. Adaptable to many environments, Redworms have been breaking down organic waste to make natural fertilizer for millions of years. They also aid in the breaking down of pathogens. These worms are prolific breeders, laying one egg capsule as often as every seven days. Each worm capsule will hatch an average of 3 to 4 earthworms. The hatched earthworms will grow into breeders in about three months. They are very popular live bait for fish that prefer small baits, such as trout, bluegill, perch or crappie. Red Wigglers are easy to use as bait, easily surviving in temperatures between 38 to 95 degrees Fahrenheit.
