Diatomaceous Earth -What It Is and How to Use It




Yum

September 29, 2014 by Andrea Fabry 119 Comments

We had a spider overrun in our garage this summer, and diatomaceous earth (DE) saved the day!

Diatomaceous earth Collage for ITT

Diatomaceous earth is natural and a great addition to any household. There are a multitude of uses for DE. (One of my favorite lists can be found at Tips Bulletin.)

Beth Haymond is an expert on this wondrous, versatile substance and agreed to answer my questions regarding the origin of DE, as well as its many uses. Beth is content writer and social media coordinator for DiatomaceousEarth.com where you can find high quality DE. (I have no financial affiliation with this company, just an interest in helping others avoid hazardous chemicals.)

What are the most common uses for DE?

Rather than trying to list the thousands of ways to use diatomaceous earth, let me just say this: if you’ve eaten gummy bears or bread in your life then you’ve already eaten diatomaceous earth. If you brush your teeth regularly, it’s likely you’ve brushed your teeth with DE. If you use soap then more than likely you have used DE.

You see, there are thousands of uses for diatomaceous earth. It keeps gummy bears from sticking together. It’s found in skin care products, toothpastes, foods, beverages, medicines, filters, and so much more.

Other ways to use DE are due to its amazing absorbency capabilities. You’ll find it in cat litter, floor dry, soil amendments among others. It absorbs odor as well, so toss a bit in a smelly garbage can or your gym shoes to keep the odor away.

It’s most well-known as a natural insecticide. When ants or any bug with an exoskeleton comes in contact with diatomaceous earth, it dries them up.  They no longer can hydrate because the diatomaceous earth sticks to the waxy layer found on the exoskeleton and prevents them from hydrating from the moisture that is in the air.

Are there any downsides to the use of DE?

It’s never going to be as strong as a chemical pesticide. It’s as simple as that. You need to be patient with diatomaceous earth and smart with your application. Since it’s a dust, it has to come in contact with the insect to work.

Of course, its downside is its upside. It’s not a chemical! This is a huge advantage to me, and you can keep it in your home as long as you want, without risking your family’s health. It may not be as strong as a chemical pesticide, but I’ve found DE pretty effective and most people agree.

What is the top misconception regarding the use of DE?

This one takes some explaining so bear with me. First off, you need to know the chemical composition of DE (which varies between mines and companies). They all look something like this:

Amorphous silicon dioxide, from diatomaceous earth 85%

Other element oxides 10%

Moisture 5%

As you can see, the main component of DE is silicon dioxide, which can range from 80 to 90 percent of DE. Silicon dioxide, also known as silica, comes in two forms: crystalline and amorphous. Crystalline silica is formed when DE is superheated.

Here is the misconception: many people think there is a serious risk with inhaling DE. There have been studies that show there can be an increased risk of cancer and silicosis after people have breathed in crystalline silica. But these studies almost always look at people in construction or mining operations. Silicosis generally happens after about twenty years of working in a site like that.

The potential carcinogenicity of crystalline silica is still being explored. But again, the people being studied are constantly exposed because of their jobs. The gist of what we know now is that you’re at risk if you breathe in crystalline silica every day, all day, for about twenty years of your life.

Sometimes you’ll read an article that says something like this: “Warning! Use a dust mask when applying diatomaceous earth because it’s toxic when you breathe it in!” This is simply not the case. To be labelled food grade DE, it cannot contain more than one percent crystalline silica.

Amorphous silica is the natural stuff. This is what makes up your DE and hasn’t been altered. DE that has been superheated and contains a high amount crystalline silica is pool grade DE. This is used in pool filters. Even with this DE, you should be fine. You’re just adding it to your pool filter after all.

To date, no carcinogenicity has been linked to amorphous silica.

With all this being said, there should still be some caution because DE is still a dust. Some people with asthma, allergies, or sensitivities should take precautions, especially when a large application is involved. Keep the area ventilated and you should be just fine.

Can you give a little background/information on your company?

DiatomaceousEarth.com took off this year in April. We sold DE before on DiatomaceousEarth.net under the brand name Pure Earth D. When a new domain opened up, we took it as a chance to create an informative, user-friendly website. We have an interactive learning center full of how-to articles with step-by-step instructions. We have a blog that we regularly update with the latest information on how to use DE. People can email, use the chat feature, call in, and Facebook us with their questions. We have lots of knowledge to share. 

Do you recommend taking DE internally?  

This is one of the more controversial topics, but I think there could be something to eating DE. We know that silica plays an important role in the body. While the exact role isn’t clear cut, silica deficiency induces deformities in skull and peripheral bones, joints are poorly formed, the mineral balance in the femur and vertebrae is disrupted, and contents of cartilage and collagen are reduced.

People who have taken DE have found various benefits. The most common benefits I hear about are healthier hair, skin, and nails. If you want to ingest DE, 1 tsp a day should do the trick.

As far as we know it shouldn’t have any negative side effects. It’s listed by the FDA as Generally Recognized as Safe (GRAS), and as we established earlier, you’ve likely already ingested trace amounts of DE.

The main problem with the benefits of eating DE is the lack of information. There aren’t many studies to back up some of the benefits people have found.

With this in mind, sometimes people will message me on our Facebook page and ask something like, “Will this cure my cancer, autoimmune disease, heart disease, lower my blood pressure, etc.?” My reply is always the same. Contact a competent medical professional, and seek proper medical attention. Do not discontinue any medicine your doctor has prescribed.

Do you have any tips regarding the application of DE?

Recognize that you will apply it differently depending on the pest you’re dealing with. When I’m protecting a plant from a slug, I apply a barrier of DE around the plant. On my dog, I push back her fur until the skin is exposed and then apply it everywhere to kill fleas.

Some steps that are always the same with most insects: clean your home like the Queen of England is coming to visit, fix or caulk any cracks, prune back foliage, and get rid of any leaks or moist areas. Unfortunately for some of our warmer states, it’s just a given that you’ll be fighting against insects most of the time. DE is in this scenario because you can always have it applied and it’s not toxic to your family. As long as you keep it dry, it will last forever.

One of my favorite things about DE is a barrier as well, which is not something many chemical pesticides are capable of. I have problems with ants every summer, but I know where they’re coming in—the crack under my front door. I put a line of DE in front of my door, and reapply when it gets washed away. I haven’t had a problem with ants since I’ve done this.

Not all applications are that easy. Bed bugs fall under this category. If you have them, buckle up because you have to do a lot to get rid of them. DE isn’t magic, but it does work. Same with chemical pesticides, you generally have to use a few methods to get rid of heavy or difficult infestations.

What is Food Grade DE?

For all your diatomaceous earth needs, it’s best to use DE that meets the Food Chemicals Codex (FCC) standards. This kind is typically referred to as food grade diatomaceous earth. It’s basically the bee’s knees of DE because it’s natural and unaltered. This is the grade you want to use as your pesticide, feed additive, deodorizer, cleaner, etc. The best way to tell if the DE is food grade is by the label on the package.

The only grade to look out for is pool grade. When DE is superheated this process causes the diatoms to crystallize. This process makes the DE into a great filter, and as the name suggests, you’ll want to only use this grade as a filter in your pool. Don’t use pool grade DE for any of the suggestions listed here.

Thanks to Beth Haymond for taking the time to help us live more naturally and avoid the health hazards associated with petroleum-based chemicals.

      I think many of the microbes would be resilient to this, but your question makes sense. This would be the reason that less is more when taking DE internally. I have taken DE in the past with no negative effects – but mostly I stick with charcoal or bentonite clay.

    Great post! My comment is actually a question. The only DE I can find in my area (in large quantities anyway) is more red-ish in color. I believe it’s called “Red Lake Earth” diatomaceous earth. It is food grade… just wondering if it’s the same stuff as the all white DE… except the color of course! Thanks!

      Jabe,
      As long as it hasn’t been heated at high temperatures it should be fine. Here is what I am reading on their website:
      “Food Chemical Codex Grade diatomaceous earth, on the other hand, is treated at a much lower temperature (non-calcined) and contains a very low percentage of crystalline silica (Red Lake Diatomaceous Earth contains less than 1% crystalline silica). Food Grade Diatomaceous Earth must also meet strict specifications in regards to heavy metal content.”
      You could ask the company exactly how high they heat it since they are saying lower temperature. That would be my only question with it.

      It is food grade. My understanding is that Red Lake Earth has clay in it. This could be the deposit itself, because every diatomaceous earth deposit is different, or it could be added later.

      Our 35# dogs get 1 teaspoon DE every morning, stirred into either a raw egg or some canned dog food. We began using it because our puppy had a sensitive system and we wanted an alternative to chemical wormers. We’ve been doing this a year and have seen no signs of worms.

      I use RLE (Red Lake Earth) DE (diatomaceous earth) for my dogs and have for years…especially my yorkie with valley fever and in meds…seems to make a difference in keeping him regular and active. Feeding to dog: sprinkle a tsp over a medium sized dog dish that feeds 2-3 small pets a day.
      I personally take 1 tsp of DE a day to keep regular BMs and help with removing daily environmental toxins from my body. It’s great for so so many uses including face masks, bug bites, itchy skin relief, of course your plants love it as well as using as a bug barrier around doors and porches. Make sure you are using CODEX food grade products (usually sold at feed and grain supply chains).

          1/2 teaspoon in water is a dose that I’ve used in the past. Some will recommend a heaping teaspoon daily. Others say several times a day. My feeling is less can be more. The texture is a bit clay-like but I find it tolerable. Some people put it in smoothies.

        Thanks for your reply. In answer to your question I asked you because I had already asked the store to call the company, and they would only say it’s not labeled food grade. It’s Manna Pro Pure DEfense diatomaceous earth.with silicon dioxide from DE-85%, other element oxide- 10%, and
        moisture-5%. Same as food grade label on shelf next to it. I wonder if it costs millions to get it certified food grade, and they aren’t allowed to say it is if they don’t spend the money. For some reason this is being made to seem very confusing. The label says poison control center common name of active ingredient is–amorphous silica from diatomaceous earth. Amazon was selling a bag of this and they answered the question for a customer with yes food grade. This will not satisfy my friends because it’s not on the label or from the company. Can anyone clear this up for everyone? It’s a common concern.

            Is the word “amorphous” all we need to know that it’s natural and unaltered? If that’s the case, you may have missed what I wrote earlier, that the poison control center information ON THIS BAG says common name of active ingredient is amorphous silica from diatomaceous earth. I just want someone to say with certainty, that this is the food grade DE. I really believe it is, but try to tell my friends that! Ha h a thanks again!

            I contacted the company and this is their reply:

            Thank you for contacting Manna Pro. Our DE is not food grade. If you have any other questions please don’t hesitate to ask.

            When I pressed the representative, here is what she said:

            It costs a great deal of more money to certify the product as food grade. The company we get the DE from did not want to pay for it to be categorized as food grade. The product is all natural and if an animal consumes it on accident nothing should happen to the animal. Legally we cannot recommend feeding it on purpose since it is not registered as food grade.

    My son’s school has had an outbreak of bedbugs and I am FREAKED out!! We always get a couple bites here and there but now I am alarmed we could have them! They were actually seen in his classroom. I bought a bottle of the stuff you puff out and we put that around our rooms as a barrier. I went to TSC and bought the Red Lake DE is this a good one to use for insects? We were also told to mix 2 tablespoons into a 32 Oz spray bottle and add water to spray our furniture. We did this but I have read it does not work when it becomes wet. But I’ve also read it turns back to powder once dry. Maybe I should just stay off google!! Lol We haven’t seen anything just doing it as a precaution. We have had those wood or Wolfe spiders too so I’m hoping it works for both!! Thanks so much!!!!

      Seems to me the spray can’t hurt – that it will dry to a powder again. So hard to know, but DE makes a great preventative either way. Nice to hear from you, Mandy!

          I’ve lived in apts for many years until i bought my house. I started using DE about 30 years ago, never had ants, roaches, or spiders in my apt. Fleas come in on your shoes, i sprinkle the DE all around and it gets them as well.

    Accidently used pool grade DE in hone for bed bugs. Freaking out because I am 9 months pregnant and have a cat and two dogs. I am extremely concerned about the health hazards this might have caused for me my baby and my animals. I was extremely careful when I sprinkled it along some baseboards and around the feet of My bed but like I said it’s pool grade not food grade thanks to my roommate who was the one who brought the bed bugs in and the said the pool grade was safe to use!!! Help!!! What do I do? !!

        I contacted RED LAKE EARTH IN Canada and understand these companies freak out when someone asks if okay for human consumption bc of the liability. Understand that USA FDA refuses to recognize the benefits of DE to be humanly consumed. FDA has warned they companies to shun any positive response in regards to DE have any health benefits; they CAN NOT admit safe or they can be sued! However, I’ve used for years and swear by the the stuff.
        General RULE of thumb when buying:
        • Do NOT buy at a hardware store where they
        Pesticides are sold. Even improper storage
        Of DE around chemicals is a BAD idea bc of
        sheer absorbency and possibility of
        Improper labeling and storage.
        • Do NOT buy at a POOL supply store or big
        Box store as the idea of them carrying the
        Right type is slim to none.
        • Only purchase at FEED & GRAIN supplies &
        There’s still items to look for.
        1. Try to look for ‘fresh water’ processed
        2. Always look for CODEX (safe for mammal
        Consumption * you won’t ever find an
        Label that state safe for humans as DE
        Is not FDA approved (codex is key label).
        For its safe for pets you are generally ok.

    For all the parents that want a natural remedy for insects, this product works, but please use the food grade. We had a major battle with fleas and if anyone has had a flea issue, it is extremely difficult to break the flea cycle. We tried everything. Then we found DE. We scrubbed our houses rom top to bottom, washed the pets, stuffed everything we could in the washer and vacuumed everything. Then we applied DE to our pets, their bedding, cat tree, under the couch, in the couch, any place where the pets slept and so far we have been completely flea free for weeks now. This stuff is a miracle and the best part is it is safe around my kids and pets.

    Ingredients: diatomaceous earth calcium bentonite. It’s a dark gray matter & fine. OMRT on the bag, listed organic material review Institute. Then it has various animals listed and pictured on the front of the bag. The bag weighs 40 pounds very heavy it’s full of clay from what from information I get online. my question is is this just for animals or is it for human consumption, I tried it and after three days mantis didn’t stop working even though I drink lots of fluid that because of the clay in it ?

    I recently bought at 50lb bag of PERMA-GUARD “Food Chemical Codex Grade” DE that has the directions: “Mixing rate: this product is for use as an inert carrier or anti-caking agent in feeds, in an amount not to exceed 2% of total diet.”

    I take this to mean that it is for animal feed, and not necessarily intended for human consumption.

    But given the FCC grading, do you think this is safe for me and my family to consume?
    We know others who take it twice a day and are all healthy but I would like to hear the opinion of a professional as well!

    Been doing and extensive research about Diatomaceous Earth DE for the past weeks. Since have a dog and I’m more into the Holistic medicine approach, myself. Surprisingly found out is a great natural dewormer and good for pets digestive system too. Knew about DE first in 2015 and his properties for pest control . Works great ! Been using MannaPro Pure DEfense (including silicon dioxide, other dioxides and moisture 100%)(THAT’S WHAT IT’S LISTED N THE BAG AS ACTIVE INGREDIENTS) followed by *AMORPHOUS SILICA. Bought it at a local Barn Store. They told me that’s food grade. Happens is about time to deworm my 85 pnds, 5 yr dog and waiting for his Rx to arrive by mail. Therefore decided to start and try DE for the 1st time today. Decided to start consuming it myself too. I’m a MS patient and learn could be of great benefits for many symptoms. Since medicine is the science of trials and errors, took chances with my guts. Started with 1 tablespoon daily for both of us. Will know and keep you posted. Going to post a couple of links about the subject, also, for your interest.

  31. Lucy Clements says

    I was given DE for bedbugs and fleas a houseguest and her dog left me. I have 2 dogs and 6 cats. I was mortified. I treated the animals and their bedding, carpets. I left it in the carpets. They were bug free in a few weeks. I got a powder applicator and went after the bed bugs. Took awhile and lots of looking for their hangouts, but I got them! I also started taking it in my smoothies daily. The first thing I noticed was that I found much more energy. After a few days I was detoxing and felt like the flu. That’s completely normal. I had plantar fasciitis and was getting treatments and prescriptions for anti-inflammatory treatments for over a year. It’s very painful hard to walk. Since I was taking DE I did not have to see the doctor again. Cured! Also, I often had terrible IBS pain that had me reeling on the bathroom floor. I haven’t had that pain since. And I’m much more regular! I guess my body needed silica! Thank God. Toss out all those other supplements that are so expensive. Try this stuff! Oh and I lost 19 pounds without trying! I feel 10 years younger!
    Hint… Start with a low dose.

    can i use this on a brown recluse bite?? Went to the ER my daughter was givin amoxicillin to take and i was told that if she gets fever or starts vomiting to bring her back we sat there for almost 4 hours and this was after they confirmed that the spider was a brown recluse(i took the spider in with me) and they told me there was nothing to do but keep it from getting infected and that if her skin tissue does start to rot to take her to a wound clinic so they can do a skin graph. I seen online that alot of people who have been bitten even small children mix bentonite powder with water and and put that on a bandage and apply to the bite and it is supposed to draw out the venom. Would this work the same as just plain bentonite?

    Hi, I’ve had a big container of Red Lake earth diatomaceous for a couple of years..unopened because I was unsure how to use it or how safe it is. Thanks for such informative posts. I’m going to start using it today. Last year I had to have surgery on my digestive system which has resulted in chronic diarrhea and now have such itchy skin with sores which seems to have been environmentally triggered. I’ve got six pet chickens so am going use it on them too. I live in the country with several wooded acres so I think I’ll treat the more used areas as well. Maybe I can post results in a timeline to show the effects. Thanks again for everyone’s posts.
