Indoor Worm Composting: How To Get Started?

#1 DIY/Buy A Bin


  • Find a suitable bin or make your own. Plastic storage bins with lids of 2.2 sq. ft. or a standard plastic storage tub are highly recommended for indoor use. They are inexpensive, durable, and lightweight. Do not use deep containers. They are heavy to move and the bedding becomes compacted making it difficult for the redworms to forage for food.
  • Drill a series of 1/4 – 1/2 inch holes in the bottom and lid of your container. Use a sharp drill bit and drill slowly. These holes will provide oxygen to the worms and other decomposer organisms in the bin.
  • Place a plastic or metal tray under the bin to catch “leachate”. These are nutrient-rich liquid that percolates through the vermicomposting bin.

#2 Set Bedding

Bedding provides the worms with a cool and moist place to live and
covers your food scraps preventing odor reoccurrence. Surely, these worms will tunnel through and digest the bedding along with the food scraps to produce compost.


  • Ripped hand-shredded newspaper or corrugated cardboard into small strips. Avoid the use of glossy or colored paper to avoid intoxicating your compost.
  • Soak strips of newspaper or cardboard and then squeeze out excess water.
  • Place the strips in your bin about 2/3 full of bedding.
