In this article we’ll cover all of the steps to store flour to prevent bugs. Weevils are the main culprit we need to worry about when it comes to flour. As it turns out, weevils lay eggs in flour kernels in the field and lay dormant for months. Occasionally an egg can make its way through the manufacturing process and end up hatching while stored in your home. We also want to ensure that no other insects or pests can get in there either. While we’re at it, we need to make sure the flour is properly protected from going rancid as well. Continue reading to learn about the steps needed to prevent weevils and how to store your flour to keep it well protected.
White flour, also known as white rice flour, can be stored for 10 years or more if stored properly. Other flours can be stored in the pantry for 3 to 6 months and in the freezer for 6 months to 1 year.
Not usually but it is possible. Weevils lay eggs in flour kernels in the fields. It’s possible for some eggs to not be destroyed during the flour manufacturing process and hatch months later inside your pantry.
Consuming flour weevils isn’t harmful but it isn’t pleasant to think about. The cooking process would almost certainly kill any live weevils leaving nothing but a protein deposit in your food. Still not ideal but it won’t hurt you or a family member.
Indirectly yes. Flour mites can spread fungus to your flour which could in turn cause someone to become ill from eating contaminated flour.
It’s best to throw out food that is infested with flour mites but you can freeze any food that has them to kill them.
Flour should have a fresh and natural smell to it. If it smells foul in any way it should be thrown out. Also, if you find weevils or other insects in it throw it out immediately.
The best way how to store food to prevent bugs is to use airtight food grade storage containers. This will only prevent new insects from getting into your flour though. If any eggs managed to get into the flour prior or during the production process you’ll have to take a different approach to make sure that didn’t happen. You’ll need to freeze your flour for 48 hours to ensure that any eggs are dead and won’t hatch creep crawlers into your food later. Good luck and happy baking.
