Diatomaceous Earth Online™   supplies premium-grade Australian diatomite (also known as natural amorphous silica).  Sourced directly from one of the world’s largest known and highest quality deposits*, our freshwater DE is taken from the ancient freshwater lakes of Mount Garnet, Far North Queensland. We process the Diatomaceous Earth directly from the mine, enabling us to ship throughout Australia and internationally, in quantities from as little as 1kg, to many tonnes, at very competitive prices. 

Our diatomaceous earth is Food Grade, 100% natural and chemical free, and has been certified by the Queensland Government as containing an undetectable amount of crystalline silica (less than 1%) . It has no additives and has not been subject to any manufacturing process other than crushing and bagging.  It is only sun-dried and has not been subject to any artificial heat treatment – making it safe to use in the home, garden and on the farm.

Whether you are a large-scale agricultural producer, run livestock, a professional horticulturist, a breeder, a home gardener, or a pet owner, you will find many uses for Diatomaceous Earth

We offer Food Grade Diatomaceous Earth in the following grades:

All are exactly the same quality, but each has been milled to a different particle size, to suit different uses.

Food grade regular is ideal for using in your garden (mixed in with garden soil), with fruit trees, with pets and livestock. It is milled to a maximum particle size of approximately 2.00mm and so is a mixture of powder and larger ‘crunchy’ particles. It is excellent for use with insects, such as ants.

No-grit Food grade superfine has many applications, and will appeal to users who are seeking a fine powder with no grit. This is exactly the same quality DE as regular, extra-milled to a maximum particle size of mostly less than 200 microns (or 0.2 mm). It is ideal for use in pet’s fur for fleas, or for bed bugs. While no DE produced in Australia has been certified for human consumption, many people do choose to eat DE, seeking to obtain the many reported health benefits. If you choose to consume DE, spread it in a baking tray and heat in a moderately slow oven of 140-160 degrees (not hotter) for about 30 minutes to ensure it is sterilised.

Chicken / bird food DE supplement is milled to a particle size of between approximately 0.5mm to 2.00mm. It is a perfect additive for mixing with regular chook and bird food.

DE potting medium additive is milled to a particle size of between approximately 5.00 mm and 15.00 mm and so is a good chunky additive, retaining moisture while providing water soluble silica at an affordable price.

*Independent comparison tests undertaken by the Russian Academy of Science found that Diatomaceous Earth from our mine in Mt Garnet, Far North Queensland, compared favourably to high quality DE from the USA and Russia.
