As for worms, these are found in gardens under rotting vegetation, and under manure piles on farms. The little redworms are surface feeders, turning waste materials into nutrient-rich vermicompost. If you buy worms, they will be sent by priority post or overnight courier. Immediately upon receiving the worms, pick out the dead ones. Add water to the prepared bedding, and place the worms on top.
All worms require oxygen, and produce carbon dioxide, just like humans.
Redworms also use microorganisms in the bedding, which help them break down, digest, and turn waste material into rich vermicompost. Never place your redworms in the direct summer sun, and never leave them out in the freezing cold. These are the best temperatures for worm health, growth, and feeding. So now you have a box with bedding and worms. Redworms will consume almost any vegetable or fruit waste.
