I have a question about sugar. I bought a 50 lb bag, then seperated it into smaller food saver bags, and sealed the food saver bags without vacuum sealing it. I plan on putting these bags int a plastic storage tub. If I buy 10 lb bags of sugar, I leave them in the paper bag and put them into food saver bags then seal them. We have ants so I am concerned about them ruining all my sugar. Is this the best way to do sugar or is there a better way?
