What is Diatomaceous Earth?

Diatomaceous Earth (DE)Quite simply Diatomaceous Earth is the fossilized remains of ancient algal shells called Diatoms or Phytoplankton. Diatoms are the grass of the waterways of the planet. Much in the same way grass is the staple food of land based herbivores. Diatoms (algae) are the foundation basis of all aquatic life and form the most plentiful group of individual species known to man. There are more types of Diatoms in the world than all land plants combined.

The Diatoms living in the waterways absorb minerals and elements from water enabling them to ‘build‘ their tiny shells. Consequentially, the fossilized remains have captured and contain the some 15 trace minerals used to form the shell. As they die the microscopic diatoms drop to the bottom of the waterways and form deposits of essentially marine sediment.

These sedimentary deposits are later mined, milled, dried and bagged creating Diatomaceous Earth or more commonly known as DE. DE is widely used internationally for a host of industrial, agricultural and horticultural applications.

Some Diatoms are salt water based, others are fresh water based. The product we sell is fresh-water DE. It is considered to be ‘Food Grade’ and has been shown to have a myriad of uses. For a number of decades fresh-water or food grade DE has demonstrated to have excellent health benefits for mammals and plants when used correctly.

Diatomaceous Earth Applications

There are a large number of uses for DE so please don't hesitate to get in touch if you have any questions.

Diatomaceous Earth is an all natural product that has an incredible number of uses:

  • In the garden:
    Diatomaceous Earth from Perma-guard has a wide range of applications and uses in the garden as a natural tool in your arsenal against pest and parasites. DE can be applied wet or dry. Application can be as simple a hand spread or choose from one of our DE tailored applicators. Alternatively mixed with water at a rate of 20gms per 5 litres you can apply via a pump up type sprayer or simply brush on items at a higher concentration.
  • In the home:
    Food grade Diatomaceous Earth is useful in controlling and discouraging insects from your home, garage, workshop, sleep-outs, sheds – just about any building where control is necessary.
  • Anti-caking agent:
    Diatomaceous Earth is a completely natural, chemical free anti-caking agent. It has very useful benefits in products and feeds that experience difficulties in pouring and flowing. Particularly stock-feeds containing molasses tend to form clumps and become sticky. Not only will the clumps become hard to pour, they start to encourage mould and potential wastage can occur. DE when mixed with the feed will coat the particles preventing them from binding together. This enables the feed to flow better making the feed less likely to mould due to the moisture absorbency characteristics of Fossil Shell Flour.
  • Grain storage protector:
    Simply remove 2% of stored grain, replace with DE and blend.
  • Commercial insecticide:
    Seriously effective on bugs, they literally have no chance with the mechanical action of DE working like razor blades once contacted with their exo-skeletons.
  • Consumption by mammals:
    Perma-guard’s Fossil Shell Flour deposit is 89 - 95 percent amorphous silica. As well as being very high in silica percentage it also contains 15 essential trace minerals including phosphorous, selenium, calcium, sodium, potassium, magnesium, copper, zinc and iron.

    As well as the trace minerals, Fossil Shell Flour particles are negatively charged (rather rare). Heavy metals, bacteria and viruses, pesticides, drug residues and the likes of E-Coli are all positively charged.

Some of the reported potential benefits of daily consumption of DE include:

  • 15 Trace minerals – beneficial for soil, plants, animals and potentially even humans
  • Better feed conversion, improves weight gain and general health
  • Promotes shinier coats, hair, skin, manes, hooves, nails and plumage
  • Reduces fleas, ticks, flies, general manure odour and fly population
  • Cost effective health supplement.

Diatomaceous Earth Precautions

  • DE production staff working in Food Grade DE mines in the US report no ill effect from prolonged and regular inhalation of dust in the workplace.
  • Despite this, dust inhalation of any kind, especially in a pro-longed nature should be considered un-healthy and best avoided.
  • We recommend exercising caution and using a mask especially when applying heavy applications and working with volume to avoid an excess of inhalation.
  • Asthma suffers or other lung ailments should certainly take extra careful and take additional precautions and be conscious not to breathe the ultra-fine dust particles.
  • Avoid getting DE in the eyes of yourself, your animals and livestock. DE is drying to the eyes, so be aware of wind direction.
  • DE can be drying to your skin, hands, and feet, similarly to your pets. If you suffer from dry skin you may consider using gloves when handling.
  • Some two legged mammals have the potential to experience a healing crisis (detox reaction) when beginning DE consumption. If this occurs, reduce the dose, increase in slow increments until RDA is reached.
  • Apply liberally on carpets and similar surfaces. There have been reports of excessive volumes of DE causing issues with certain vacuum cleaners.
  • Ensure all spray equipment is cleaned after use to avoid DE leaving residue deposits in the tank, pump, nozzles etc. Simply flushing with clean fresh water for a minute until clean will suffice.
  • DE has the potential to kill beneficial insects as well, exercise discretion particularly with flowering plants where bees may frequent in season.
  • DE has absolutely nil withholding period when sprayed on fruit and vegetables destined for human consumption. It is harmless and you could spray, pick and eat it all in the same day! What other insecticide can claim that !!!
  • NEVER use pool filter grade, industrial grade or any diatomaceous earth other than those labeled "Food Grade" for yourself or your animals. It can poison or kill them.
  • Don’t settle for anything less than Perma-guard Fossil Shell Flour for your home, your family, pets, farm or horticultural uses. Fossil Shell Flour is the purest, most refined food grade DE available in the world that we know of. Perma-guard have achieved OMRI (Organic Materials Review Institute) status for Fossil Shell Flour – certified Organic in the United States. New Zealand Organic status has recently been granted by BioGro - BG5339.
