Repeating this process will eventually soak out a lot of the moisture. The remedy for this is to divide the worm population, placing half into another bin, or giving some away. Also, make sure you are feeding the worms well. Check to make sure the bottom of the bin isn't becoming compacted, it may be time to remove the old castings and replace with fresh bedding material. Worms that are sexually mature have a prominent 'band' around their body, called the 'clitellum' Most worms are 'hermaphrodites', which means that each worm has male and female reproductive organs.
Reproductive material is exchanged.
When the worms seperate, a ring of mucus material forms at the clitellum of each worm. The worm will then wriggle backwards, and the mucus ring slips off over the head. All the necessary reproductive material is sealed inside. The capsule will then hatch, producing from 2 - 20 baby worms. The average is about 4.
