I store it in a tin( figs and rogue lip balm tin). I have emptied the lip balm and reusing the same tin. I live in london and I dont see any ants around in my hose. So i dont have this problem. I apply only once in a day(that too mon-fri only) no lip balms on sat and sun. My lip balm is in oily form as it has only mixture of oils and nothing else. I hope this helps.
