Container

• Surface area and light penetration are the two major concerns when it comes to choosing a worm-composting container. Red worms are sensitive to light, so choose an opaque container and keep it out of direct sunlight.
  
  An opaque plastic tub with a tight fitting lid makes a good indoor worm-composting container. Choose a tub that is roughly 10 inches deep, 15 inches wide and 20 inches long or that provides one square foot of surface area per pound of food waste to be composted in a week. Do not use a container deeper than 10 inches; red worms feed close to the surface and food in the bottom of a deep container can develop a foul odor.
  
  Drill at least two eighth-inch to half-inch holes in each side of the tub, about 4inches below the lid, to allow air inside for the worms. Tape small pieces of window screening over the holes to keep bedding material from falling out.
  
  

Bedding

• Provide your worms with organic bedding material; this will provide both a beginning food source and a habitat for your composting worms. Shredded cardboard or newspaper, aged straw, and rotting leaves all make great worm bedding.
  
  Moisten the bedding material before adding worms; add enough water so that the bedding has roughly the same moisture as a wrung sponge. Another good way to add moisture is to mix the bedding with some moist food waste and leave it for a week before adding worms; the bedding will soak up moisture from the food and provide your worms with an excellent environment from the start.
