Be careful where you put the worm box and what it's made of. I collected nightcrawlers one spring/summer and kept them in a large styrofoam cooler in my backyard. They had actually started to reproduce and I had a couple hundred in there. I went out to get a few one day and found a mole or something similar had chewed through the styrofoam and eaten every last one! It felt so wrong, but I went Big5 and bought a dozen.
