I have posted new instructions for making a worm bin. Earlier this year, I had an accident when drilling in the side of bins, and I am now recommending you make holes in the top of your bins.
I was drilling holes in the side and the drill slipped off the plastic and hit me in the leg. Fortunately, I was wearing pants and I didn't hurt myself.
This scared me and made me think. Why drill holes in the sides?
The worms don't care where the holes are, and the sides are sloped and flex when you try to drill the holes (both of which make it harder than it needs to be).
Holes in the nice flat top would be so much easier. So I tried it and viola! Works just as well and it is much easier.
My revised worm bin instructions are on the Your Bin page.
