Add the worms. Pull aside some of the bedding, bury the food waste and cover it up. Construction Build a wooden worm bin, buy a plastic tub with a lid, or use an old trunk or drawer. Wooden containers are absorbent and good insulators.
Plastic containers maintain a constant moisture level.
Raise the bin on bricks or wooden blocks for air circulation and to protect from freezing in winter. Place a tray underneath to capture any excess moisture. Cover the bin to conserve moisture and provide darkness for the worms. Use a sheet of dark plastic or dampened newspaper on top of the bedding to retain moisture and discourage fruit flies. Worm bins may be located outdoors, or in a shed, on a deck or under the kitchen sink.
