Egg capsules are lemon-shaped and about the size of a match head. After 14-21 days baby worms hatch from the eggs. One to five worms emerge from each egg. In 60-90 days, the young worms are mature. Try to find mature worms, young worms and worm eggs in your worm bin.
Worms can live as long as four years.
When worms die in the bin, their bodies decompose and are recycled by other worms, along with the food scraps. Worm castings are toxic to live worms. After all the food scraps in a bin are recycled, the worms will eat their own castings which will poison them. Harvest your worm bin when it is filled with compost. Contrary to popular belief, worms cannot reproduce by being cut into small pieces.
