Key Considerations For Diatomaceous Earth

Diatomaceous earth 101

Diatomaceous earth consists of fossilized remains of a type of algae known as diatoms, namely carbonaceous algae. Small particles of silica, or silicon dioxide, contain this natural chemical compound.

As diatomaceous earth was formed, it first occurred in an ocean, a river, a lake, a pond, and a stream millions of years ago. The sediment of these bodies of water contains their remains, which contain the silica found in diatomaceous earth. Diatomite is mined today in these areas that used to be home to diatoms to make diatomaceous earth, a useful and natural substance.

Uses for diatomaceous earth

You may not be aware of just how versatile diatomaceous earth can be unless you use it frequently for a specific purpose or are just learning about its many benefits. Here are some of the most popular uses for this natural sediment.

Pest control

Diatomaceous earth is favored by many people as a natural way to kill insects because it is poisonous to insects and does not pose any danger to plants, animals, or humans. In this way, it works both indoors and outdoors to remove bugs from almost any surface.

When pests ingest diatomaceous earth, they dehydrate because it causes their bodies to dehydrate or be pierced by its sharp edges. An example of an insect and arachnid that diatomaceous earth can control is ants, fleas, bedbugs, spiders, ticks, cockroaches, and mites.

Industrial purposes

As well as its agricultural applications, diatomaceous earth is used in the production of food and medicine, and pet products. Filtration and cleaning are also possible with it. Several consumer-grade forms of these forms are available for pool filtration; however, most of these applications do not directly benefit consumers.

Dental health

Are you aware that many brands of toothpaste contain silica? This is because the fossilized diatoms have a slight gritty texture that helps whiten teeth and removes plaque buildup that can cause cavities. Mix a bit of food-grade diatomaceous earth with your toothpaste if it does not contain silica.

Dietary uses

Beauty: Diatomite fossils aren’t the only sources of silicon. Several minerals and rocks contain silicon dioxide, which is also called silicon dioxide. Silica is also found in our bodies, making it a great supplement for improving the strength of nails and hair as well as promoting collagen production to make us look younger. Furthermore, it may also reduce skin conditions such as eczema and delay the effects of ageing.

Health: Several body systems may benefit from silica in diatomaceous earth. In addition, it may be able to relieve constipation and act as a digestive system detoxifier. Silica may also be able to lower blood cholesterol levels. In the same way that silica-rich diatomaceous earth strengthens hair and nails, it may also strengthen joints and cartilage, relieving related pain.

Is diatomaceous earth proven to have beauty and health benefits?

There haven’t been conclusive studies conducted on diatomaceous earth taken orally for various ailments since the Food and Drug Administration doesn’t closely monitor dietary supplements like it does medications. The fact that it appears to have so many benefits is widely acknowledged, but concerns have been raised about how it may interfere with the body’s use of some nutrients. Thus, before taking it, you should consult your doctor.

Features of Diatomaceous Earth

Forms of diatomaceous earth

Consumers can select between three types of diatomaceous earth: food-grade, pest grade, and filter grade. The most common type of diatomaceous earth available on the market is food-grade. Silica is mostly insoluble and is only present in a small amount. It is the only form of herbal product that can be consumed and is quite concentrated in strength. Although some food-grade diatomaceous earth is also suitable for pest control, it is not recommended.

Pesticides labelled “pest grade” rather than “food grade” should only be used to kill insects and spiders. Remember, however, that many people equate food grade and pest grade.

It can contain up to 60% crystalline silica and is only used for industrial purposes. Diatomaceous earth used for filters does not contain this type of silica. Diatomaceous earth is sometimes referred to as pool grade due to its use in pool filters. Diatomaceous earth of this type should never be consumed.


Bags of diatomaceous earth weighing from 1 lb. to 50 lb. are most commonly used to buy diatomaceous earth. Dusters are sometimes included in bags for easy application.

For easy storage, diatomaceous earth can also be found in tubs of various sizes with tightly sealed lids. It is possible to purchase diatomaceous earth in bottles that contain only a few ounces of the powder.


Despite the fact that diatomaceous earth is non-toxic, natural, and safe for humans and pets, you should make sure to take some precautions before using it.

Do not inhale it. You can suffer from coughing, sneezing, or throat, nose, or lung inflammation. Wear a dust mask when applying it indoors, especially if you need to touch surfaces.

If you plan to take it orally, consult your physician. Keeping this in mind before you take any supplements is a good rule of thumb. Diatomaceous earth should not be consumed by people with digestive diseases, such as IBS and Crohn’s disease. A flare-up or worsening of symptoms is possible.

Keep it away from unintended uses. Diatomaceous earth comes in various forms because each of them has different properties. To get the best results, choose the appropriate form according to the application.

Children and pets should not have access to it. While diatomaceous earth is harmless, it can cause harm to animals and children if ingested or inhaled in large quantities.

Diatomaceous Earth Prices

The price of diatomaceous earth depends on its use and the size of the packaging.

Inexpensive: It costs between $5 and $10 for a bottle of about eight ounces, but it isn’t enough for large projects or frequent use.

Mid-range: Diatomaceous earth comes in bags or tubs weighing about 3 to 10 pounds, with prices ranging from $14 to $35. Compared with most pet control options, diatomaceous earth that is food-grade can be a bit more expensive. However, bulk bags usually cost one dollar per pound.

Expensive: Pool grade diatomaceous earth typically costs between $1 and $2 per pound and is sold in bags of 25 to 50 pounds.

Tips on Choosing Diatomaceous Earth

Are your plants infested with aphids? Diatomaceous earth is a natural pesticide that can be applied to leaves to help keep small insects at bay.

As diatomaceous earth contains no harmful chemicals, it is a safer alternative to insecticides for pets that frequent your garden area.

If you choose to take food-grade diatomaceous earth as a supplement, you can mix it with your favorite beverage to add it to your diet.

It is not a good idea to take diatomaceous earth in excessive quantities, even if you enjoy the effects you get from using it in your diet. Follow the directions on the packaging or the advice from your doctor if you wish to stay safe.
