I learned about reusing (carefully cleaned and dried out) juice bottles to use to store dry foods like lentils, rice, flour, sugar, etc. I am excited to do this. I am also using milk jugs but some people would only use PETE plastic. Here are some links. https://www.thriftyfun.com/Reuse-Jugs-for-Dry-Foods.html https://theprovidentprepper.org/packaging-dry-foods-in-plastic-bottles-for-long-term-food-storage/ it should keep insects out but rodents can chew through the plastic. if you have a rodent problem you can just store the jugs of food in thicker plastic containers though
