Vermicomposting is using worms, bedding, and food scraps to make compost inside or outside your home. Some books say to dig up earthworms from your own garden, but I just bought the basic set-up from Susan (a.k.a. Worm Girl). It came with a blue plastic bin with pre-drilled holes, bedding, and red wiggler worms all for the small sum of $25. She even delivered it!
I've been vermicomposting for a couple of months now, and all is well. I already harvested some compost for my houseplants. There was bit of smell at one point, and two worms escaped (and dried on the wall of the cabinet), so I added more paper to create a less humid environment, and things have now equalized out.
If you're in Montreal, I would buy worms from Susan. All the other places I called were out of worms or were charging a lot for them. I didn't call any bait shops, but that was suggested in a book I read.
