Updated: 1 day ago


food grade diatomaceous earth

Food grade diatomaceous earth (DE) has seen a surge in popularity among health enthusiasts, gardeners, and pet owners alike. As a versatile product with a wide array of uses, ranging from being used in supplements to an effective pest control solution, its appeal has grown rapidly. But what exactly makes food-grade diatomaceous earth so special? In this post, we’ll explore what DE is, how it’s produced, its practical benefits, and how it can be safely used.



What is Food Grade Diatomaceous Earth and Why is it So Popular?


Diatomaceous earth is a naturally occurring, fossilized mineral made from the remains of tiny, aquatic organisms called diatoms. Over time, these diatoms accumulate in the sediment of rivers, lakes, and oceans and form a chalky, silica-rich substance. Food-grade diatomaceous earth is a specific type that is purified and safe for human and animal consumption. Unlike its industrial counterpart used in pool filters, food-grade DE has a significantly lower level of crystalline silica, making it non-toxic and safe for a variety of uses.

The process of creating food grade diatomaceous earth begins with mining the fossilized remains of diatoms from freshwater sources. After extraction, the material is milled into a fine powder. The product is then carefully tested to ensure that it contains less than 1% crystalline silica, which makes it safe for use around humans, pets, and even in food production. This careful preparation ensures food grade DE remains highly absorbent, non-toxic, and retains its essential mineral content, especially silica, which plays a crucial role in its health benefits.



Source of Food Grade Diatomaceous Earth

The source of food grade diatomaceous earth (DE) is fossilized remains of diatoms, which are microscopic, single-celled algae that lived in oceans, lakes, and rivers millions of years ago. These diatoms had cell walls made of silica, a natural mineral. Over time, the silica-rich skeletons of these organisms accumulated in large deposits on the seabed or lakebeds, eventually fossilizing into a soft, chalky sediment known as diatomite or diatomaceous earth.


How Food Grade DE Is Sourced:


  1. Mining: The diatomite deposits are mined from ancient lake beds and seabeds, primarily found in various regions worldwide, including the U.S. (especially in California and Nevada), Mexico, China, and parts of Europe.


  2. Processing: After mining, the diatomite is processed by milling it into a fine, white powder. For food grade DE, it undergoes specific treatments to remove impurities and ensure a very low crystalline silica content (less than 1%), making it safe for human and animal consumption.


Food grade DE is distinct from other types, such as pool grade DE, which undergoes further treatment that increases its crystalline silica content, making it hazardous for health purposes.

Food grade diatomaceous earth can be used in various ways, depending on your needs. For health enthusiasts, it’s commonly ingested in small amounts to aid digestion, detoxification, and support healthy skin, hair, and nails due to its high silica content. It can be mixed into water, juice, or smoothies, and consumed daily as a supplement. In agriculture and gardening, it’s often used as a natural pesticide, working by absorbing fats and oils from the exoskeletons of insects, which leads to dehydration and death. Additionally, pet owners use it as a non-toxic insecticide to rid their pets of fleas and ticks, and it’s also added to livestock feed to promote internal cleansing.



Application Methods

The application methods of food grade diatomaceous earth (DE) vary depending on the intended use, such as health supplementation, natural pest control, pet care, or gardening. Below are the most common methods for applying food grade DE in these different contexts:


1. Health Supplementation


Food grade DE is often used as a natural supplement for its purported health benefits, such as detoxification, digestive health, and mineral intake (mainly silica).


  • Oral Consumption:


    • Mix with Water or Juice: The most common way to take DE as a supplement is to mix 1 teaspoon to 1 tablespoon of DE powder in a glass of water, juice, or a smoothie. Stir well to avoid clumping and drink it immediately.


    • Increase Gradually: Start with a smaller dose (1 teaspoon) and gradually increase the amount to up to 1 tablespoon per day, depending on personal tolerance and intended use.


    • Best Taken on an Empty Stomach: Many users take DE in the morning on an empty stomach, allowing for better absorption of its detoxifying properties.


    • Add to Foods: Food grade DE can be mixed into yogurt, oatmeal, or other soft foods, though it's important to maintain hydration by drinking water throughout the day due to DE’s absorbent nature.


Note: Always use food grade DE for consumption, as other types, like pool grade DE, are not safe for ingestion.


2. Natural Pest Control


DE is highly effective as a natural, non-toxic insecticide. It works by physically damaging the exoskeletons of insects, causing them to dehydrate and die. It is commonly used for controlling ants, fleas, bed bugs, and other household pests.


  • Indoor Application:


    • Dust Lightly Around Pest Entry Points: Apply a fine dusting of DE around window sills, doorways, baseboards, and other areas where insects are likely to enter your home. A small amount is enough to be effective.


    • Apply Directly to Infected Areas: For ants, bed bugs, or cockroach infestations, sprinkle DE directly onto the affected areas, such as cracks, corners, or even on mattresses and carpets (for bed bugs).


    • Reapply After Cleaning: DE can be vacuumed up, but it should be reapplied after cleaning to maintain its effectiveness as a barrier against pests.


  • Outdoor Application:


    • Create a Barrier: Sprinkle DE around the perimeter of your home or garden to create a natural barrier against pests such as ants, slugs, or earwigs.


    • In the Garden: DE can be sprinkled lightly on the leaves of plants to protect against pests like aphids, beetles, and caterpillars. Reapply after rain or watering as moisture reduces its effectiveness.


3. Pet Care and Livestock Use


Food grade DE is often used to protect pets and livestock from parasites like fleas, ticks, and worms.


  • Flea Control:


    • Direct Application on Pets: For dogs and cats, sprinkle a small amount of DE directly onto their fur, working it into the coat with your hands. Be careful to avoid the animal’s nose, mouth, and eyes, as DE can cause irritation if inhaled.


    • Bedding and Sleeping Areas: Dust your pet’s bedding or sleeping area with DE to help control fleas. Leave it on for a few hours or overnight, then vacuum it up. Repeat as needed.


  • Deworming:


    • Internal Use for Pets and Livestock: For internal parasites, DE can be mixed into pet food or livestock feed. Use 1 teaspoon for small dogs or cats, and 1 tablespoon for larger dogs, horses, or other large animals. Ensure plenty of water is available, as DE’s absorbent nature requires adequate hydration.


    • Chicken Coops and Barns: For poultry or livestock, sprinkle DE in the bedding or nesting areas to control mites, lice, and other parasites. This helps keep the environment clean and healthy for the animals.


Note: Always consult with a veterinarian before using DE for internal or external parasite control for pets.


4. Gardening and Agriculture

DE is widely used in organic gardening and farming for its pest control properties and its ability to improve soil quality.


  • Soil Amendment:


    • Mix with Soil: DE can be mixed directly into garden soil to improve its structure, aeration, and drainage. It helps retain moisture while allowing air to reach plant roots. Use approximately 10% DE in the total soil mix for best results.


  • Pest Control:


    • Sprinkle on Plant Leaves: Lightly dust the leaves of plants with DE to protect against soft-bodied pests like aphids, caterpillars, and beetles. It can also be applied around the base of plants to prevent slugs and snails from attacking.


    • Reapply After Rain: DE loses its effectiveness when wet, so it should be reapplied after rain or watering to maintain its pest control properties.


5. Household Uses


  • Odor Absorption:


    • In Fridges or Trash Bins: DE’s absorbent properties make it a great natural deodorizer. Sprinkle a small amount in the bottom of trash cans or in the refrigerator to absorb unwanted odors.


  • Moisture Absorption:


    • In Damp Areas: Use DE in closets, basements, or other damp areas to absorb moisture and prevent mold growth. Place DE in small containers or sprinkle it directly on surfaces.


6. Skincare and Beauty


  • Exfoliation:


    • Add to Skincare Products: DE can be mixed with water, oils, or skincare creams and used as a gentle exfoliant. Its fine, abrasive texture helps remove dead skin cells and improve skin texture.


  • Detox Bath:


    • Add to Bathwater: Some users add DE to bathwater for its purported detoxifying properties. Use about 1/4 cup of DE in the bath and soak for 20-30 minutes.


Food grade diatomaceous earth is a versatile natural product with a wide range of application methods. Whether used as a health supplement, natural pesticide, pet care treatment, or soil amendment, it is essential to use the appropriate method for each specific purpose. Always apply DE in a well-ventilated area and avoid inhalation to ensure safety.
