Since worms will naturally migrate towards food and I'm not a fan of cleaning out my worm bin, I looked at some commercially available composters and decided I could make one. As the worms eat the food in the bottom bin and move up to the next one, you're left with super compost without the tangled mass of worms.
Step 1: You Will Need...
-- At least 3 stackable totes with lids. I used shoebox sized Rubbermaid totes but Styrofoam coolers would work too. Consider the amount of scraps your family created in a week to help choose the size of bins. 2 people live in my house and we don't generate much scrap.
-- A drill
-- A large drill bit. I used a 21/64 because that's what I found in the basement.
-- 4 small plastic containers to use as risers. I used small yogurt cups (not shown)
-- Some newspaper, shredded
-- A handful of dirt. For indoor composters, bug free potting soil.
-- Red worms
