Diatomaceous earth (DE) is defined by OSHA as an amorphous silica composed of the microscopic skeletons of prehistoric diatoms and containing less than 1% crystalline silica.
Under a microscope, diatoms are generally round or tubular with sharp edges.
DE is touted as having many health benefits, including some government studies linking it to improved skeletal effects and lower blood cholesterol.
But is all DE the same? And if not, which DE products should you buy? How should you use them?
In this Pest Strategies review, we’re going to answer those questions by looking at different types of diatomaceous earth, the claimed health benefits, the pros and cons of using it, and how to use it for the best results.

5 Best Food Grade Diatomaceous Earth
Are you short on time or just want a quick answer?
What Is Food Grade Diatomaceous Earth?
Food grade diatomaceous earth is a dietary supplement often used to treat issues with the digestive system. It is safe for human consumption and the Food and Drug Administration (FDA) says it isGenerally Regarded as Safe (G.R.A.S.).
That means it doesn’t require any special labeling or permissions to be sold for human consumption or use. Diatomaceous earth products can be ingested to help with detoxification, to facilitate hair growth, and for issues with the digestive tract.
It’s a white powder that can be mixed with smoothies, water, milk, coffee, or any other beverage. It can also be added to your toothpaste to help whiten your teeth. It alsostimulates collagen production in the connective tissues of your body.
Pure diatomaceous earth is 85-90% amorphous silicon dioxide. By contrast,pool filter grade or swimming pool grade diatomaceous earthhas a much higher crystalline silica content.
How Does Food Grade Diatomaceous Earth Work?
The most common human health use for food grade diatomaceous earth is to cleanse the digestive system. It purges all sorts of parasites, toxins, heavy metals, radiation, and bacteria due to its’ unique shape and size, without any noticeable side effects.

In all fairness, however, we should point out there areskeptics who doubt there are any health benefits to using diatomaceous earth. They mainly cite the lack of scientific studies as their reason for doubting its effectiveness.
It should be noted that what they disparage as “anecdotal evidence” is also known in court as “eyewitness testimony” and criminals have been sent to jail based on it. There are many people with eyewitness testimony to the effectiveness of diatomaceous earth.
Is Food Grade Diatomaceous Earth Effective For Killing Pests?
Absolutely. Diatomaceous earth is adesiccant. It absorbs moisture and causes anything that comes in contact with it to dehydrate.
Insects are so small that any loss of moisture can be deadly to them. It also cuts their exoskeleton and drains moisture that way too.
Any infestation of insects can be reduced by applying diatomaceous earth to cracks and crevices with a powder duster. Many people prefer it because it is a natural product rather than a chemical insecticide.
How To Use Food Grade Diatomaceous Earth?
Start with a level teaspoon mixed with 8-10 ounces of your favorite beverage. Follow that with a tall glass of water, then wait half an hour before eating. Diatomaceous earth is, well, earth, so it tastes like mud. A few drops of honey helps with the taste.
Start by doing this once a day, then over a period of 2-3 weeks, gradually increase it to twice a day, then a few weeks after that, three times a day.
Keep in mind that diatomaceous earth will dehydrate you, so drink lots of water.
Is Food Grade Diatomaceous Earth Safe Around My Pets and Children?
Yes. Diatomaceous earth can be lightly sprinkled on your pet’s food every day as a dewormer.
It helps absorb odors in kitty litter boxes and you work small amounts of it into your pet’s coat to protect them from fleas and ticks. It has many barnyard uses too.
Diatomaceous earth is also safe for children to drink the same way you do. You’ll have to reduce the amount to compensate for their smaller size, but that’s all.
How Do You Find the Best Food Grade Diatomaceous Earth?
- The first thing to look for is the words “Food Grade” on the label of the product. If that’s not on there, it’s probably pool or filter grade diatomaceous earth for use in a swimming pool filter. It works better than sand.
- Another thing to look for is anOrganic Materials Review Institute (OMRI)designation. That means it has been tested by OMRI and passed their certifications for the purity of ingredients and for organic use.
- Also, look for “botanical” or “herbal ingredients” on the label. Diatomaceous earth with those kinds of additives isn’t as pure as OMRI listed diatomaceous earth, but it is still safe for human consumption.
