Perma-Guard Fossil Shell Flour is the world’s finest food-grade diatomaceous earth. This natural solution is suitable for almost all animals and livestock and helps improve digestion, gut health and nutrient and mineral absorption.




Fossil Shell Flour is a natural product derived from the fossilised remains of microscopic shells of freshwater aquatic organisms called diatoms. This 100% pure plant based whole food is an ideal, natural solution for optimising animal and livestock health.


Safe to use on most animals and livestock, diatomaceous earth provides a chemical-free alternative for internal and external parasite control. Rich in silica, DE will help improve your pet’s skin and coat, reduce odours and improve gut health.




The benefits of Fossil Shell Flour (diatomaceous earth) can include:


  • Help with internal and external parasite control
  • Increases detoxification and removal of heavy metals
  • Improves gut health and acts as digestive aid
  • Helps improve joint, bone and ligament health
  • Contains minerals including Calcium, Magnesium, Zinc, Iron and is 93% Silica
  • Stimulates basic metabolism
  • Reduces odour and moisture in barns, stalls and litter boxes
  • Cost effective and reduces annual veterinarian bills



Directions/dosage + storage:


Mix with food. For small pets under 24 kg, use half to one teaspoon per day. For larger pets, use half to one tablespoon per day. 


Alternatively, add 1-2% of the weight to the feed rations. This does not have to be an exact amount, more will not be harmful, but less may not give you the results.


For external parasite control, make a paste with water or rub full-strength powder on to the skin and/or apply to the coat and sprinkle on bedding.




Q: Is Fossil Shell Flour safe for all animals?


A: Diatomaceous earth is safe for consumption and use around most animals. However, due to its ability to absorb moisture, it is not recommended to use with reptiles and insects. If unsure, consult with your veterinarian prior to use.

Q. Does your Diatomaceous Earth kill Bed Bugs, fleas, weavils and other pest insects.

A. Although Diatomaceous Earth has been proven to kill many pests (including Bed Bugs, fleas, weavils etc.) by mechanical action (google it), our product is not a registered insecticide, so we cannot sell it as such.

What minerals are in it?


  • Amorphous Silica: 89 – 95%
  • Calcium: 0.407%
  • Iron: 0.25%
  • Potassium: 0.107%
  • Magnesium: 0.138%
  • Phosphorus: 0.00937
  • Silicon: 0.342
  • Zinc: 0.000754
  • Plus, other trace elements.


How do I use Fossil Shell Flour to help with parasite control?


Although Fossil Shell is not a registered for pesticide control, it is a great alternative. While most pesticides are highly toxic, Fossil Shell Flour is a non-toxic natural product.


For best results, lightly sprinkle Fossil Shell Flour onto your pet’s fur and rub or even comb into skin. Alternatively, you can mix the powder with water and make a paste and then apply to your pet’s coat. You can also dust a small amount of powder onto your pest’s bedding.

Perma-Guard is the original and largest supplier of registered food-grade diatomaceous earth products in the world and is imported from the United States. Not all Diatomaceous Earth is Food Grade. There are many cheaper versions of Diatomaceous Earth starting to flood the market in Australia, we suggest you check that the product is registered/certified food grade before making any purchases as many types can contain impurities making them unsafe for consumption. To date, there is no Australian Diatomaceous Earth that is certified as Food Grade.


Some Diatomaceous Earth claimed as food grade contain higher amounts of sediment and clay that make them less effective. Depending upon how the deposits were formed, clay particles may be present in sufficient quantities to clog the pores of the fossilized shells. If this is the case, the effectiveness of the Diatomaceous Earth is severely reduced. The shape of the diatom must be tubular with holes in the walls. It must be fresh water because the diatoms form a harder shell and are less fragile than those in saltwater. Perma-Guard Fossil Shell Flour DE is registered Food Grade and is 100% pure, organic and contains no chemicals.

Out of 600 deposits in the USA, only 4 are considered "Food Grade" by the FDA standards.


Warning: When purchasing Food Grade Fossil Shell Flour Diatomaceous Earth, you should be looking for something that is off-white/bone in colour. There is a large comparison in colour, this is mainly due to clay deposits found in the Australian and other countries products.


Perma-Guard Food Grade Fossil Shell Flour (DE) - amorphous silica as diatoms (microfossils) is more than 99% and the crystalline silica is generally regarded as less than 0.5%.

PERMA-GUARD is the trade name for a grade and quality of Diatomaceous Earth (DE) and comes from the USA. Actually, DE is not an earth. It is the fossilized remains of microscopic shells of freshwater plankton Algae/plants called DIATOMS.

These products do not contain persistent chemicals harmful to the environment and to higher forms of life. Although not harmful to animals or the environment generally, it may be harmful to fish.


Perma-Guard is uniquely Natural, Organic and Sustainable.

All diatomaceous earth is not the same. Diatomaceous earth packaged under our Fossil Shell Flour (FSF) label comes from an extremely pure freshwater deposit of the diatom Melosira Preicelanica. Why is this diatom so special? Its shell is made of amorphous silica. Its shape and hardness are important to how it works. Its hardness keeps it from dissolving in liquid. The holes along the diatom's wall allow it to absorb moisture.


Why fresh water vs. saltwater DE? Fresh water deposits like ours have a consistent diatom presence. Their fossilized shells have maintained their tubular shape. This shape and strength of the fossil shell is critical to its effectiveness. Our deposit has very high amorphous silica content. Our deposit is more consistent in purity of other elements that have settled in it. Saltwater deposits contain a mix of types of diatoms of different shapes. Their fossilized shells are fragile and break easily. This renders them ineffective for our purposes. The saltwater deposits are less predictable in their sediments.


What's the difference between amorphous and crystalline silica? Amorphous silica is silica in its natural occurring state. It is a trace mineral every mammal on the planet needs to gain full health. It becomes crystalline when it is exposed to extreme heat through volcanic activity or commercial manufacturing means, e.g. the type of diatomaceous earth used in swimming pool, and other, filtration systems are crystalline silica. Crystalline silica is extremely dangerous when inhaled or ingested. It is not biodegradable.


In Australia, Food Grade Fossil Shell Flour has only been approved for sale as an Anti-Caking Agent and animal feed, therefore we can only advertise it as such. Please see the manufacturers website to find out more or research on the internet (google, YouTube etc). In Australia it is currently not approved as a human health product, in other countries such as USA and Canada the Perma-Guard brand of Fossil Shell Flour Food Grade DE is approved by PMRA & Health Canada, USDA, FDA and EPA.

Suggested feeding instructions:
Add 1-2% of the weight of the feed rations. It doesn't have to be exact. More will not be harmful, but less may not give you the results expected.

* Avoid inhalation (as with all small particles they can cause health issues if breathed in).

Storage Conditions:
For best results store sealed in a cool dry place.
