Diatomaceous Earth

36 mins read

Diatomaceous earth is a kind of powder made from the sediment of fossilized algae discovered in bodies of water. Since the cells of these algae were high in a compound called silica, the dried sediment produced from these fossils are likewise very high in silica. These deposits are discovered all over the world. The ancient greeks used diatomaceous earth to make structure materials, like bricks and blocks. Later on it became popular in europe for various industrial uses.

When taken by mouth, diatomaceous earth is used as a source of silica, for dealing with high cholesterol levels, for dealing with constipation, and for enhancing the health of skin, nails, teeth, bones, and hair.

When applied to the skin or teeth, diatomaceous earth is used to brush teeth or eliminate unwanted dead skin cells.

Diatomaceous earth is likewise utilized in industry. It is used to eliminate undesirable material from drinking water. It is also utilized as a filler or to prevent development of lumps in foods, medicine, paints and plastics, and animal litter. It is utilized to tidy up spills or for insulation in industry, in addition to scrub things. Diatomaceous earth is used as part of various chemical tests. It is also utilized as an insecticide. [2]


Diatomaceous earth, which was first believed to be a kind of limestone, was found around 1836-1837 by peter kasten while drilling a well in haußelberg hill which lies in lüneburg heath in germany. After its discovery, it was utilized by alfred nobel to make dynamite and also by wilhelm berkefeld for establishing filter candle lights. [3]


Each deposit of diatomaceous earth is different, with differing blends of pure diatomaceous earth integrated with other natural clays and minerals. The diatoms in each deposit consist of various quantities of silica, depending upon the sedimentation conditions, on the presence of other sediments (clay, sand, asheses), and on the age of the deposit (diagenesis, silica dissolution/precipitation, diatoms tests ageing). The species of diatom may also vary among deposits. The species of diatom depends on the age and paleo environment of the deposit. In turn, the shape of a diatom is determined by its species.

Many deposits throughout british columbia, such as red lake earth, are from the miocene date and contain a types of diatom referred to as melosira granulata. These diatoms are roughly 12 to 13 million years of ages and have a small globular shape. A deposit consisting of diatoms from this date can supply particular benefits over others. For example, diatoms from the eocene epoch (around 40 to 50 million years old) are not as reliable in their capability to soak up fluids due to the fact that as older diatoms recrystallize, their small pores become filled with silica. [4]

How does diatomaceous earth work?

The pests’ body fluids leak out and within a short time this loss of fluid triggers them to die of dehydration. Diatomaceous earth can act internally, too. When pest consume de, it soaks up the fluids in their bodies, likewise triggering dehydration that eliminates them. For insecticide functions, the diatom shells are pulverized into a dust so that it will quickly cling to pest bodies. Diatomaceous earth is fatal to insects because its minute dust particles are razor sharp and act like shards of broken glass, lacerating and piercing the insects’ bodies. The injuries become deadly as vital fluids drain out, and the bugs rapidly pass away. [5]

Varieties of diatomaceous earth

Food-grade and filter-grade ranges

Silica exists in 2 primary kinds, crystalline and amorphous (non-crystalline).

The sharp crystalline form looks like glass under a microscopic lense. It has residential or commercial properties that make it preferable for many commercial applications.

The two main types of diatomaceous earth vary in their concentrations of crystalline silica:.

Food grade: this type contains 0.5– 2% crystalline silica and is used as an insecticide and an anti-caking representative in the agricultural and food markets. It is approved for use by the epa, usda, and fda.

Filter grade: also called non-food-grade, this type consists of upwards of 60% crystalline silica. It is harmful to mammals however has numerous industrial usages, including water purification and dynamite production. [6]

Color and types

The different colors of diatomaceous earth reflect the local distinctions of diatomite deposits from all over the world. Varying in color from light grey to brown to white, diatomaceous earth is graded by the purity of silica and the quantities of other minerals. For ‘food grade’ de, there need to be no more than 10mg/kg of lead or arsenic.

The diatomaceous earth discovered on the retail market is available in two kinds, swimming pool grade and food grade. Swimming pool grade is calcined or treated with high heat, which turns the silica dioxide into crystalline silica. This procedure emphasizes the filtering qualities of de but makes it extremely harmful to the breathing systems.

Food grade diatomaceous earth is a freshwater form of diatomite. Although it can cause slight lung inflammation over long exposure, it’s safe to use topically and is frequently taken as a health supplement. Property owners and gardeners may be more familiar with food grade de since it’s low-cost and an important tool in many pest management techniques. [7]

Advantages of diatomaceous earth

Diatomaceous earth (d.e.) Is a naturally happening soft, sedimentary rock made from the fossilized remains of tiny aquatic creatures called diatoms, which are a group of algae.

The skeletons of these unicellular organisms are made of silica and have collected in the sediment of rivers, streams, freshwater lakes, and oceans all over the world for numerous thousands to millions of years. These silica-containing deposits are mined for both industrial and food-grade usage.

What is silica?

Diatomaceous earth is a focused source of silica. Also known as silicon dioxide, silica is commonly discovered in nature in quartz, clay, sand, and living organisms. Silica is highly sought after for commercial and industrial use, as well as its possible health benefits.

If the idea of consuming silica sand for health appears hard to swallow, remember there stand out distinctions between filter-grade and food-grade diatomaceous earth. Filter-grade d.e. Includes toxic amounts of silica harmful to mammals and is mostly for commercial use. It can be especially harmful to people when inhaled.

Food-grade d.e., however, is purified and is usually acknowledged as safe for both human beings and animals by the u.s. Food and drug administration (fda). In addition, food-grade d.e. Might have some health benefits for people such as reduced bad (ldl) cholesterol, remedy for constipation, and improved nail and hair health, however there is insufficient scientific research to support these claims.

Talk with your medical professional before taking d.e. Supplements to assist treat a health condition considering that the majority of claims about the product have not yet been verified in clinical settings.

Health benefits

Marketing for diatomaceous earth supplements makes some quite considerable health claims. Nevertheless, health claims for dietary supplements are unregulated by the fda, which means there is no assurance of security, efficiency, potency, or purity of any supplement, consisting of d.e.

Because of the lack of evidence-based nutrition research study, it’s not suggested to take d.e. Supplements at this time. But there are other ways to increase your intake of silica by taking in certain foods and beverages containing this mineral.

Silica is a mineral that’s vital to the formation of collagen in your body, but rather than taking a d.e. Supplement, nutrition specialists advise selecting foods that are high in silica such as:.

  • Bananas and dried fruit
  • Beans (certain types)
  • Beer and red wine (in small amounts)
  • Dairy and meat items
  • Green beans
  • Mineral and sparkling water
  • Nuts and seeds
  • Oats
  • Rice
  • Tea and coffee
  • Wheat

Health claims

There are a variety of anecdotal claims that food-grade diatomaceous earth supplies health advantages. However the greatest issue about these claims, according to ginger hultin ms rdn cso, a spokesperson for the academy of nutrition and dietetics, is the absence of inadequate and trustworthy proof relating to the security of using this item. Here’s a closer take a look at some of the health claims.

Body detoxing

Proponents say that d.e. Can get rid of toxic substances and heavy metals from the digestive tract to “detox” the body. Filter-grade d.e. Is an industrial-grade filter that removes heavy metals from water, but this “cleaning” effect has not been shown in human beings with food-grade d.e. In general, the majority of health professionals do not endorse products with health claims promoting detoxification and cleansing.

Improved digestion

The “detoxifying” properties of d.e. Claim to clean out the colon, which supporters state will enhance digestion function and promote regularity by increasing the frequency of defecation.

Bone health

Silica is discovered in trace amounts in connective tissues throughout the human body, so some people believe it helps with the healthy aging of the bones and joints. Due to the fact that d.e. Is made almost entirely of silica, which is important for cartilage formation, some claim that the product helps to reinforce bones and joints also. Emerging research on silicon and bone health is appealing however remains uncertain.

Improved hair, skin, and nails

Supporters declare that silica can likewise enhance the skin, hair, and nails. Silicon dioxide is also found in numerous hair products. Some individuals have actually said that d.e. Supplements can produce fuller, thicker, much healthier hair within a couple of weeks of regular usage. Likewise, it is said that silica assists with collagen production to improve skin texture and look and might also strengthen nails.

Increased energy

Anecdotal claims report that taking d.e. Supplements during the day can increase your energy levels, but again, there is no evidence to support this.

Decreased inflammation

Proponents have stated that d.e. Supplementation can assist battle swelling in the body. While there is no evidence to back this claim, some research study has in fact shown the inverse. A 2015 follow-up study of diatomaceous earth workers who inhaled excessive amounts of silica showed increased inflammation and circumstances of lung illness.


Research study on diatomaceous earth for weight reduction is unclear at this time. There have been some research studies about taking it to help lower cholesterol (ldl and triglycerides), however larger, more rigorous research studies are still needed to better comprehend the security and efficacy of using d.e

. The bottom line is that health claims for taking diatomaceous earth are mainly theoretical given that insufficient human research studies have actually been performed. [8]

Slug prevention

Slugs have their preferred plants– marigolds, hostas, sunflowers, basil, cabbage and lettuce– simply among others.

If you have a bounty of slugs in your garden, you might wish to consider raising yard ducks, or take the simple method and spray some diatomaceous earth around your most preferred plants.

Natural pest control

De is one of the very best non-toxic ways to get rid of bugs in the garden. However, it does not discriminate, so beware where you spread it, you do not wish to put it on flowers where bees will be gathering pollen, for example.

It works well to eliminate numerous insects, because the fine, dry powder is extremely dehydrating. As they crawl over it, the diatomaceous earth is soaked up by the soft skin and they pass away slowly from dehydration. It may take a week, or two, to see results, but it works and lasting.

Get rid of unwanted ants

One way to eliminate ants is to cover their nest with wood ash. If you do not have any leftover ash from your wood stove or latest campfire, diatomaceous earth is the next best alternative.

Merely dust the anthills and surroundings with powder to motivate them to relocate.

Aphid control

A bounty of aphids can quickly get out of hand as they feed upon young plants and shoots, drawing the sap as if their lives depended on it (because it does!). They have the capability to eat and eat, till an entire plant is gone.

A quick treatment is to dust an aphid infested plant with powder, alternatively blending it with water in a sprayer and using it damp, waiting for it to dry to do its work.

Always be sure to rinse your garden produce well if you have actually previously applied diatomaceous earth.

Prevent rodents in your yard and garden

Mice, moles, rats and rabbits are all garden visitors that might visit for a bite or more, however if they are consuming the entire buffet …

Likely, you’ll wish to prevent them from consuming excessive, and thankfully there are some things they do not delight in. As diatomaceous earth is so absorbent, you can position little containers of it in the garden along with a couple of drops of peppermint or citrus necessary oils to assist curb their hungers.

Prevent tick, mite and flea numbers from growing too large

While you can use diatomaceous earth straight to the fur of your farm animals, there might be times when you want to stop these annoying visitors at the gate, so to speak.

Edges are where ticks and other crawling bugs get in the lawn. Good news is, you do not need hazardous chemicals to stop them.

1 to 4 tablespoons of diatomaceous earth per gallon of water produces a great spray provision. Utilize it liberally on your lawn, shrubs or in the garden.

Feed it to chickens and other stock

Besides the truth that diatomaceous earth treats all sorts of intestinal tract parasites, it is also beneficial to feed de to your chickens for other factors. Studies show it can cause larger eggs, including more albumen, in addition to bigger, much healthier girls.

Goats with lice will benefit from a good douse every from time to time, just as pigs are at a benefit consuming it as a dewormer.

Mix it with your potting soil

Diatomaceous earth is extremely light-weight and porous, making it an excellent substrate for hydroponic growing and bonsai cultures.

Including it to your basic potting soil will help to increase drainage, in addition to air blood circulation around the plant roots.

Diatomaceous earth in the home

The majority of our lives we invest a great deal of time bringing the outdoors in. Nature has so much to provide by way of holistic treatments and treatments, that it is tough to turn the very best components away.

Diatomaceous earth is no exception.

A natural deodorizer

Much like with baking soda, diatomaceous earth can be sprayed inside foul-smelling sneakers and left overnight, to rid the shoe of undesirable smells.

It can be used on carpets and carpets too, integrated with 10 drops or more of your favored essential oils for a greener tidy. As mentioned above, bear in mind inhaling the dust, and ensure to vacuum completely after an hour or two, leaving the windows open for some fresh air.

Natural, indoor insecticide

To get rid of indoor ants, simply apply diatomaceous earth directly where the line goes into and exits.

For more severe problems, such as non-toxic methods to get rid of bed bugs, de is definitely on the list of natural elimination methods, however do not depend on it alone. Declutter, clean, apply diatomaceous earth, and repeat, for as long as it takes.

Chemical-free cleaner

In the restroom, de has a special use– you can make a paste of it, together with vinegar and lemon vital oil to keep your faucets, sink and shower sparkling clean. It is a mild abrasive, that can quickly be washed down the drain.

Take in spills

Diatomaceous earth can absorb up to twice its weight, making it a super stain cleaner.

Sprinkle the dry powder over a wet spill, then vacuum or sweep it up. If essential, you may need to take additional procedures with hot soapy water, however it can take in the bulk of the spill. [9]

How to use it

You may have wondered, “is diatomaceous earth poisonous or healthy for human beings?”

Diatomaceous earth is safe for humans and animals to take in, and it’s likewise beneficial for skin, so it’s utilized both inside and outside the body. Just be sure to inspect the source, and make certain your product is food-grade. Avoid utilizing internally if it is not.

The u.s. Food and drug administration lists food-grade diatomaceous earth as “usually recognized as safe,” which implies that it’s lawfully allowed to be added to various kinds of foods, drinks and supplements. Small amounts of silica are generally present in all body tissues and typically found in urine, too, so it’s well-tolerated and not known to cause many adverse effects.

What is diatomaceous earth used for? De products have been utilized for years on the outside of buildings, on farms, in gardens, and in human and pet foods.

In addition, today there are over 150 pesticide-related items registered for usage both indoors and outdoors that contain de. There are also countless non-pesticide, food-grade diatomaceous earth products that are used on the skin, in food, in products for pets, and in supplements or medications.

There are a number of methods to utilize de. A few of the most popular diatomaceous earth utilizes include:

  • Family pet nutrition products
  • Products utilized on family pets like dogs and cats to kill fleas
  • Bed bug-killing treatments
  • Sprays and items used for bug control, including cockroaches, crickets, fleas, ticks, spiders
  • Rodent sprays
  • Water filters
  • Skin care products
  • Toothpastes
  • Foods and drinks, such as in beer and white wine
  • Anti-caking and clarifying active ingredients utilized in food manufacturing
  • Supplements and medications
  • Rubbers and paints utilized in building
  • Abrasive products used as defoliators and for cleaning

Here are the advised ideas to register for safe use of de as a detoxing agent and to safeguard bones and joints (however always consult with your health care provider before beginning a brand-new supplement regimen):.

  • Take about one teaspoon of food-grade diatomaceous earth with liquid once a day. It’s best utilized on an empty stomach a minimum of one hour prior to or more hours after eating.
  • Consume an extra cup after each dose of de to improve its impacts. In general, ensure to take in a lot of water with de and remain hydrated.
  • Increase your dose gradually over several weeks, working your way up from one teaspoon to 2 teaspoons daily, or one tablespoon max. Divide the dosage into two parts taken in the morning and one in the evening.
  • Take de 10 days on and 10 days off for 90 days to effectively and safely detox. Another method is to take it daily for a couple of weeks at a time as you track signs, stopping and starting again throughout the year. It’s best when you give your body breaks and do not use it continually for very long periods of time.
  • As a note of care, initially you might observe some moderate side effects that can develop as your gut environment modifications, yeast dies off and your body releases kept toxic substances. This can include mild headaches, tiredness and flu-like signs, which need to lessen within a couple weeks.
  • Wondering what de tastes like? If you consume diatomaceous earth, you’ll discover that it’s essentially tasteless and has a rough, gritty texture.
  • You can take it with liquid, even enhancing the taste with juice, yogurt or a shake if you prefer. It will not liquify when blended into liquid, so it’s normal to see some residue.

  2. Apply diatomaceous earth powder where needed in your house, backyard, carpets, car, etc. Rub the powder into the carpets with a broom. Use enough to carefully cover the surface area however not too much that it’s easy to breathe in a lot.
  3. Let the powder sit for about four to 12 hours before vacuuming. It’s advised that you duplicate this procedure as soon as a week for a total of three to 4 weeks. This procedure can be done every few years or as required. [10]

Side effects of diatomaceous earth

There is inadequate trusted information to identify if diatomaceous earth is entirely safe. Scientists have actually not concluded any guaranteed adverse effects. Nevertheless, inhaling it might trigger serious respiratory complications, especially if the client currently has breathing issues. For instance, it might worsen conditions like asthma and chronic obstructive lung illness (copd). The supplement is likewise very abrasive, so it may cause irritation and injuries on the skin as a topical. [11]


Diatomaceous earth is improved with minerals and naturally taking place silica and offers a series of unbelievable advantages. At diatomaceous earth online, we offer food, animal and pest grade de of high quality. If you are looking for diatomaceous earth dosage, the following guide can assist you get a concept about the suggested amounts. [12]

Unique safety measures and warnings

Pregnancy and breast-feeding: there is not enough reliable info about the safety of taking diatomaceous earth if you are pregnant or breast feeding. Remain on the safe side and avoid usage.

Lung disease: some types of diatomaceous earth may be damaging to the lungs, particularly if breathed in. Breathing in diatomaceous earth might lead to lung problems in people that currently have some problems in their lungs. This consists of asthma, persistent obstructive pulmonary disease (copd), and so on. Usage cautiously. [13]


The need to gradually withdraw from the chemical-based pesticide policies to more sustainable and environmental approaches is, at the present, one of the most challenging elements of bug management. The existing decline in the registered pesticides will certainly continue, increasing at the same time the need to develop novel, reliable however also environmentally suitable substances. On the other hand, the intro of a new pesticide is an expensive and long procedure, making the total overdrawn from the traditional protectants an impractical scenario. Thus, inert dusts such as des may have an essential role to play in future insect management techniques, guaranteeing a plentiful supply of safe and healthy food and feed. Des hold fantastic potential as carriers of common insecticides, minimizing the required application dosages of the latter. In addition to synergistic results, integrated applications may likewise minimize the unfavorable effects of the compounds and can be more compatible with the preferred requirements for food security and protection of human health and the environment. Nevertheless, the introduction of other representatives must be constantly evaluated under the prism of the potential unfavorable effects they may hold, such as for example the adoption of entomopathogenic fungi representatives. Nevertheless, the application of insecticides and acaricides with a different mode of action may be a solution for the control of resistant arthropod populations, which is a hot subject in contemporary incorporated insect management. Although there are plenty of information for their insecticidal and acaricidal homes, little progress has actually been made regarding the optimum processing of de dusts used as insecticides and acaricides. Today, many industrial de formulations are prepared through a fundamental process of quarrying, drying, and crushing the mined heterogeneous rocks. This simplistic treatment leads eventually to formulations with excellent irregularity in their physicochemical qualities, affecting simultaneously their insecticidal/acaricidal homes but also some residential or commercial properties of the product itself. Therefore, more particular techniques of processing must be discovered to standardize the production of dusts bearing the most desirable features for increased insecticidal effectiveness.

Application techniques and systems of des are also an issue of major significance, needing additional investigation. Even with the current de formulas, different application methods, such as utilizing slurries or treating only partial layers of the food, should be explored. Therefore, research must be performed under a series of food-handling facilities to create efficient procedures for pest management however likewise to figure out the results of sanitation on the efficiency of de dusts. Such real-scale applications may highlight the capacity of des and explore methods of integrating de applications within the overall pest/vector management program in food industry, farming and urban settings.

The information from lab studies underline the insecticidal and acaricidal worth of des under a vast array of arthropods. Additional analysis should be carried out towards this direction not just to recognize all the target types but also to examine the general outcome of des in non-target species. Indeed, by analyzing the existing literature, we observed that non-target effects of de have been examined only on a minimal number of natural opponents of crop insects, with special referral to aphidophagous coccinellids, lacewings, anthochorids, and phytoseiidae termites, revealing restricted consequences for these important biocontrol representatives. In this appealing scenario, additional research study ought to be committed in understanding the prospective non-target results of de-based formulas. [14]
