My dad told me to freeze my scraps before adding them to the bin, and it was a game changer
When I first started with my little countertop bin in my 600 square foot Chicago apartment, I was just tossing stuff in as I cooked. My dad, who's gardened for years, saw my setup and said, 'You're gonna get fruit flies. Put those scraps in a bag in the freezer first.' I thought it was extra work, but after a week of tiny flies buzzing around my kitchen, I gave it a shot. I started keeping a gallon zip-top bag in the freezer door for coffee grounds, onion skins, and apple cores. It completely stopped the flies, and it also made the whole bin less soggy and smelly because the frozen stuff doesn't break down into mush right away. Now, adding to the freezer bag is just part of my routine. Has anyone else found that this helps keep the balance right in a small, closed system?
