Food grade diatomaceous earth (DE) is a versatile, natural product that has found its way into many homes for its myriad uses. If you’re looking to harness the power of DE in your kitchen, this guide will walk you through its benefits, safe application methods, and how to use diatomaceous earth in your kitchen to ensure maximum effectiveness.



 


What is Diatomaceous Earth?

Diatomaceous Earth is a fine, powdery substance made from the fossilized remains of microscopic aquatic organisms called diatoms. These remains are composed of silica, a naturally occurring mineral that forms the backbone of this powerful material. DE comes in two main forms: food-grade and industrial-grade. For kitchen use, only food-grade DE is safe and appropriate.



 


Benefits of Using Diatomaceous Earth in Your Kitchen

  • Natural Pest Control: DE is an excellent, non-toxic way to manage pests like ants, cockroaches, and pantry moths. Its sharp microscopic edges cut through the exoskeletons of insects, causing them to dehydrate and die without the use of harmful chemicals.


  • Odor Absorption: DE can act as a natural deodorizer. Placing a small dish of it in your pantry or fridge can help absorb unpleasant odors.


  • Moisture Absorption: Thanks to its absorbent properties, DE can keep dry goods like flour, sugar, and grains free from excess moisture, preventing clumping and spoilage.


  • Food Storage Aid: DE can be mixed with stored grains and legumes to deter pests while preserving freshness.


  • Eco-Friendly Cleaning: As a mild abrasive, DE is ideal for scrubbing stubborn grime on kitchen surfaces or cookware without scratching.

1. Pest Control


  • Identify Problem Areas: Look for cracks, crevices, and entry points where pests may be entering.


  • Apply Sparingly: Use a small dusting of DE along baseboards, under cabinets, and near appliances.


  • Reapply as Needed: DE loses effectiveness if it becomes wet, so refresh it regularly in humid environments.


Note: Keep DE away from food preparation areas during application to avoid accidental ingestion.



2. Grain and Dry Goods Storage


  • Preparation: Mix 1-2 tablespoons of food-grade DE per 1 pound of grains or legumes.


  • Mix Thoroughly: Ensure even distribution to coat the surfaces of the grains.


  • Usage: Rinse grains before cooking to remove any residual powder.



3. Odor Control


  • Placement: Fill a shallow dish with DE and place it in the back of your fridge, pantry, or under the sink.


  • Refresh: Replace the powder every few weeks to maintain its effectiveness.



4. Cleaning


  • Mild Abrasive Scrub: Mix DE with a bit of water to form a paste. Use it to scrub pots, pans, or greasy surfaces.


  • Surface Cleaner: Sprinkle DE directly onto spills or greasy spots, let it sit for a few minutes, then wipe clean.



 


Safety Precautions



  • Use Food-Grade Only: Industrial-grade DE is not safe for household use, especially in the kitchen.


  • Avoid Inhalation: DE is a fine powder and can irritate the lungs if inhaled. Wear a mask when applying or handling it.


  • Store Properly: Keep DE in a sealed container in a cool, dry place away from moisture.

Diatomaceous Earth is a powerhouse tool for any kitchen, offering a natural, chemical-free way to control pests, manage odors, and maintain cleanliness. By using food-grade DE responsibly and effectively, you can enjoy a safer and more sustainable kitchen environment.
