Flour can begin to grow mold within a few days to a few weeks, depending on the storage conditions. If kept in a warm, humid environment, mold can develop more quickly, while cooler, drier storage can prolong its shelf life. Generally, it's best to store flour in a cool, dry place in an airtight container to minimize the risk of mold growth.
If it is properly stored and never exposed to enough moisture for mold to grow, it will never mold.
