I used an old cooler and use a peice of carpet to cover the top. I keep the carpet moist by either putting it under the spigot or just pour some water over the top lying in the box. You can buy "worm food" or use chicken mash for food.
I have a question though. I have had a problem with a little red mite that gets in and will kill the worms! Within the food sprinkled on top, you can see them like masses of oversized "red bugs", also known as jiggers. How do I get rid of them without killing my worms and how to prevent the recoccurance?
