I would recommend adding a layer of browns on top of every addition of food waste. This will keep your pile more balanced in terms of C:N ratio and moisture, and will help keep the insect population down by covering the juicy stuff. Check the Browns and Greens list thread at the top of the forum if you need ideas. I use sawdust and wood shavings from my shop, you can also use wood chips from the utility tree trimmers, pine shavings sold in bales for horse bedding, shredded office paper, cardboard, etc. etc.
