I have a question about vermicomposting in the city. I have done some mid-scale operations in the rural setting, helping with school cafeteria composting projects where there is little concern about rodents. I'm in Detroit now and I would like to help a soup kitchen in my church (and maybe schools or other projects) compost all of their food waste. Many people that I've mentioned the idea to have been concerned about rats. There is very little written in any of the books that I've seen about rat prevention other than avoid animal products. I was wondering if you have any knowledge about problems with rats and if so any suggestions for overcoming them. Any info would be a great help. Thanks!
