How many times have you reached into your cupboard only to find that the flour you bought last month is crawling with weevils or smells rancid? Proper preparation and storage of flour will help prevent bug infestations and make your flour last for up to 7 months.

Difficulty: Easy
Time Required: Varies.

Here's How:

  1. Put flour in strong, food grade plastic bag. If the flour bag is packaged in paper, put the whole bag inside a food grade plastic bag.

  2. Remove excess air from bag.

  3. Freeze flour for two days, 48 hours, to kill off weevils or insect eggs in the flour.

  4. Store flour in a food grade plastic container with tight fitting lid. Keep in cool, dark place to prevent insects from getting at the flour and to prevent sunlight from spoiling the flour.


  1. Keeping flour in the refrigerator will prevent spoiling.

  2. Keep your storage area clean to prevent insect infestation.

  3. Multiple 5 pound bags of flour can be frozen individually and stored in a food grade plastic tub with tight-fitting lid.
