First and foremost, there are two types of DE: food grade and pool grade.
Food grade, or Food Chemical Codex Grade, DE meets health and safety standards established by the FDA. Food grade diatomaceous earth is safe for use in homes and as a nutritional supplement.
Pool grade DE is not safe to eat or use around your home because of impurities and its high heavy metal content.
Food grade DE is composed of around 85-95% amorphous silica. Amorphous silica comes from fossilized seashell deposits found in fresh water. Pool grade DE is made of crystalline silica, which has been heated through natural or commercial processes.
How Do You Use DE?
1. Pesticide
Diatomaceous Earth is often used as a natural pesticide. The silica-based shells of the fossilized diatoms are like shards of glass to insects. When insects walk across the diatoms, the DE cuts their exoskeletons, which injures and dehydrates the insects. Yes, this is brutal, but flea, ant, and bed bug infestations are also brutal.
In order to use DE as a pesticide, you sprinkle it over the affected indoor or outdoor area. If you are trying to kill pests in your garden or on the patio, DE is an effective solution. Beware that DE kills crawling insects indiscriminately. You could harm beneficial insects by applying this product.
If you are treating an indoor area, be prepared for dust. You will need to wear a mask while you are applying the DE, and let it settle before you reenter the area. Your skin may also become dry due to the awesome dehydrating powers of DE.
There are duster tools available to help you apply the product evenly. You can also suspend some DE in liquid and spray it in the area you wish to treat. DE is not effective when it is wet, but once it dries, it regains its potency.
Following the instructions for DE is critical to reaping the benefits of it. When you sprinkle DE onto your carpet, you are committing to leaving it on the carpet for a week or more. If you vacuum it too quickly, then it will not have a chance to be effective. With indoor infestations, you might have to apply DE more than once depending on the life cycle of the critter that you are exterminating.
2. For Pets
DE is often used as a flea treatment and dewormer. To get rid of fleas, rub DE into your pet’s coat. For internal use, consult your veterinarian first to be sure DE is a good option for your furry friend.
3. Health Improvement
When using DE as a dietary supplement, start by consulting a health care professional. If you are cleared to use DE, integrate it into your diet slowly so that you can adjust. DE is usually added to a smoothie or yogurt in order to make it more palatable. It should not have a strong taste, but it will affect the texture of its carrying agent.
Dehydration is possible when you use this product. Drink extra water while you are consuming DE as a supplement.
Regulations
FDA
When a manufacturer states that their product satisfies FDA regulations, they are verifying that the product was handled and packaged in a way that minimizes health risks.
Products that pass FDA muster are also considered safe for ingestion. FDA regulations do not address the specific health benefits of DE. The health applications of DE have not been verified or supported by the FDA, but research from a myriad of other sources reveals potential medicinal uses for DE.
OMRI
If you are a gardener or farmer interested in organic agriculture, then you will need to pay attention to the Organic Materials Review Institute (OMRI) listing for the product. This listing is critical if you are trying to label your produce as certified organic.
Many product labels boast that they are on the OMRI-list. When I checked the most current OMRI listings for this roundup, I found that many products that claimed to be listed are not on the list.
Other Considerations
Packaging
When it comes to DE, not all packaging is created equally. Since DE is a fine powder, it is messy. If you opt for a product that doesn’t have a nice resealable container, make sure you have something to place it into so that you don’t wind up with a mess and wasted product.
DE dust is white to off-white. I have used this on a cream-colored carpet with no ill-effects, but if you are worried about staining, color test a small area first. Due to the fineness of the powder, DE can wreak havoc on a vacuum cleaner.
Some DE brands come with scoops or applicators to make it easier to use the product with minimal waste.
