Quite frankly – this is NOT one of our personal favorites when it comes to methods of keeping infestation at bay for food storage. Please do not take this (solely or any other recommendation) as the end all authority. We are hoping to share options with you – for you to draw conclusions and decide the best plan for your family.
With that said, on to the other method option: Using Diatomaceous Earth
There are several different types of Diatomaceous Earth .
Make sure you get the kind that is approved for human consumption
Popular Questions
How does Food Storage Method #6, using diatomaceous earth, protect stored food?
Food-grade diatomaceous earth can help control insects by damaging the protective waxy coating on their bodies, causing them to dehydrate. It works best when applied as a very light, dry dusting around stored grains, beans, and other susceptible foods. The powder must remain dry, because moisture reduces its effectiveness. It should be used alongside clean containers, dry food, and regular inspections rather than as a substitute for proper storage.
Is diatomaceous earth safe for use in this food storage method?
Only use a product specifically labeled food grade for Food Storage Method #6: Diatomaceous Earth. Do not use pool-grade or industrial diatomaceous earth, which may contain hazardous crystalline silica. Avoid breathing the dust by applying it carefully in a well-ventilated area and following the product label. Keep the container sealed and prevent unnecessary exposure for children and pets.
How much diatomaceous earth should be used with stored grains?
Use only the amount directed on the food-grade product label, since concentration recommendations vary by product and food type. A thin, even coating is generally preferable to a heavy layer that creates excess dust. Mix or distribute it carefully so the food is lightly covered, then store the treated food in an airtight container. Label the container with the product used and the treatment date for easier rotation and inspection.
What are the limitations of diatomaceous earth as a food storage method?
Diatomaceous earth works only while it stays dry and in contact with crawling insects, so it will not reliably control every pest or infestation. It does not replace moisture control, airtight packaging, sanitation, or regular checks for damaged food. Discard food with active infestation, mold, or an unusual odor according to local food-safety guidance. If pests continue after treatment, identify the source and use a control method approved for the specific stored food.
