Appreciation post: freezing my citrus peels before tossing them in the bin killed the fruit fly problem for good
I was fighting gnats in my kitchen for 3 weeks until a neighbor in Austin told me to keep a ziplock of lemon and orange peels in the freezer and only add them to my countertop bin once they're frozen solid, and I haven't seen a single fly since, has anyone tried this with coffee grounds or onion skins too?
