Hi Anne I have not had much computer time so I was unable to reply before this. The freezer is a good place to store flour. I have two 32 quart lock lid containers.
One for my flour and one for sugar. The sit on my pantry floor. I also have heavy garbage bags inside each of them.
When I finally empty all the contents out (about once a year) I check the bag for open spaces and replace. But if you do not have room for this I would suggest the freezer, especially the ziploc bags. It will keep the flour fresh and no bugs. Gail N.E.
