Diatomaceous earth and how it works
Diatomaceous earth is made from the fossilized remains of tiny aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. Over a long period of time, diatoms accumulate in the sediment of rivers, streams, lakes, and oceans. Today, silica deposits are mined from these areas.
Silica is very common in nature and makes up 26% of the earth’s crust by weight. Various forms of silica include sand, emerald, quartz, feldspar, mica, clay, asbestos, and glass. Silicon, a silica component, does not exist naturally in its pure form. It usually reacts with oxygen and water to form silicon dioxide. Silicon dioxide has two naturally occurring forms: crystalline and amorphous. Most diatomaceous earth is made of amorphous silicon dioxide. However, it can contain very low levels of crystalline silicon dioxide. The first pesticide products containing silicon dioxide (diatomaceous earth) were registered in 1960 to kill insects and mites.
Diatomaceous earth goes by many names other than diatomaceous earth, including: 
Diatomaceous Earth is a mineral-based pesticide.
Its composition is approximately
- 3% magnesium
- 5% sodium
- 2% iron
- 19% calcium
- 33% silicon
- several other elements.
Diatomaceous earth is not poisonous; it must not be eaten to be effective. Diatomaceous earth causes insects to dry out and die by absorbing the oils and fats from the cuticle of the insect’s exoskeleton. Its sharp edges are abrasive, speeding up the process. It remains effective as long as it is kept dry and undisturbed.
DE has to be dry to be effective. Daily watering, heavy dew, and frequent rain can make using DE a hassle. Ensure you don’t apply it when the ground or plants are wet, and keep it away from areas that collect runoff water.
When diatomaceous earth is dry, you can sprinkle it where needed. You can sprinkle it on plants, the ground, the patio, in obviously infested areas, or wherever you need it. You can use a sifter or a duster. Sifters will help you get an even application, and dusters will make it easier to apply a fine layer to the leaves of plants.
It’s also possible to mix diatomaceous earth with water and spray it. This is the easiest way to get DE to hard-to-reach areas of plants, like underneath leaves and on branches. Wet diatomaceous earth will stick to the plants and become effective once it dries out. The label on your bag may have specific measurements to make a spray, but if it doesn’t, four tablespoons per 3L of water should do the trick.
How Long Does it Take Diatomaceous Earth to Work?
Depending on the insect and the conditions, this process can take a few hours to a few days. An article in National Geographic says, “Death comes in 12 hours after insects venture into diatomaceous earth. Their skins are pierced by sharp edges of the diatom’s siliceous shells, causing life’s juices to flow out.” It has been reported that some insects die within 4 hours of contact, and others may take an entire day. While individual insects can be eliminated relatively quickly, a whole infestation can take longer.
DE is effective against many pests, including ants, aphids, earwigs, mites, slugs, snails, thrips, vine borers, beetles, cockroaches, and other crawling and soft-bodied insects.
It is harmless to earthworms, as they do not have a chitinous waxy coat. However, if applied in large enough dry quantities in the garden, it could dehydrate other beneficial insects. However, mixed into compost /soil or growing media watered frequently in the recommended quantities does not pose a problem.
Since diatomaceous earth can rid you of many insects and garden pests, it’s worth mentioning that it may be harmful to beneficial insects that act as pollinators, including bees and butterflies. You can easily avoid harming them by paying attention to how and where you apply the powder. Pollinators almost always land on flowers, so avoid putting DE on any part of the flowerhead.
To achieve complete control, you should reapply DE about once a week for a whole month. This is because new eggs will hatch, and the nymphs and adults must all contact the powder for it to be effective. Since direct contact with diatomaceous earth is required, proper placement and application are essential. A thin layer of DE can be spread where insects have been known to live and travel.
How long will diatomaceous earth continue to be effective? Indefinitely, as long as it remains dry.
Although it may not be the fastest method of insect control, diatomaceous earth is chemical-free, easy to use, and has the added benefit that insects can not develop resistance to it since it is a mechanical means of pest control.
Diatomaceous earth improves moisture retention in potting mix, soil, and sandy soil by holding more fluid and drying slowly. DE will aerate the soil so the roots can breathe better, producing more robust, vibrant plants.
DE has a higher free silica content, so it is advisable to wear a mask to avoid inhaling the dust. The dust is an irritant that can cause coughing and breathing issues if inhaled, making your eyes and skin itchy. Wear a dust mask, safety goggles, long-sleeve clothing, and gloves—even if it’s food-grade—to prevent yourself from inhaling it. Keep children and pets out of the area until the dust has settled completely.
