Q: I have two compost questions: I live in Chicago and really want to start composting this summer. But my biggest fear is attracting more wildlife (translation: rats!) to the compost pile. I would like to purchase an inexpensive (if possible) closed system to work with. Does anyone have any recommendations? ...And secondly, I have a LOT of straw baskets left over from office lunches and catering. Can i compost these? They do not look varnished or treated.
