Hi. My worm farm is just needing to start from scratch. So, thankfully you gave me the idea of multiple drawers. So I'm going to buy two. How do you prevent moths? A cover? There are opening in the sides of the drawers. I think I'm just going to sift two inches and put it all in a drawer. Then pick out the beetles...in their drawer. And, the pupae in a baggie like yours...I had to laugh...what a good idea. I'll just sift the beetle drawer into another new one in so many increments. Given this, how does my plan sound? Thank you again for your help.
