Super Fine DE benefits for Livestock

DE has received recognition around the world as a beneficial feed additive for all livestock. It has been used as a digestive aid, mineral and trace element supplement and for parasitical control. It is used extensively in the USA and Europe, its use in Australia has been limited by its supply.

Livestock to benefit include Beef and Dairy Cattle, Horses, Poultry, Goats, Pigs, Sheep and Domestic Animals. Though this list does not limit the types or breeds of animals DE will benefit.

 Studies show a general to significant improvement in the following areas:

  • Optimizes animal health

  • Control of internal parasites (will not control heart or lung worm) and external parasites

  • Reduced odours – particularly noticeable where intensive farming practices are in use

  • Controls flies, ticks, fleas, buffalo fly on the animal, in pasture and around pens

  • Reduces infant mortality

  • General improvement in wellbeing

  • Greater resistance to disease and parasites

  • Improved appetites in picky eaters

  • Healthier appearance

  • Improves growth and development

  • DE will also provide the animal with calcium, magnesium, potassium, phosphorus, zinc, and sulphur trace elements 

In addition to the above improvements and in relation to specific animals:

Dairy Cows 

  • Increase in milk production and butterfat %

  • Incidence of mastitis reduced

DE in Cattle

  • Increased in weight gain

  • Improvement in coat sheen

  • May control worms and parasites

  • May control fleas, buffalo flies, ticks-internal    and external

  • Increase feed intake in prepared feeds


  • Greater weight gain

  • Reduction in odour

  • Less destruction of housing


  • Improvement in coat sheen

  • Cured scours

  • Better food absorption

Dogs and Cats and Domestic Animals

  • Controlled internal parasites completely within seven days


  • Increase in egg production

  • Control of Bird lice

  • Dryer droppings allowing easier cleaning of house

  • Feed supplement

  • Controls internal and external parasites

  • Reduces smell, controls fly

  • Improves quality of eggs

How it works

It is thought that DE works in ways similar to holistic medicine, benefiting the entire animal. It is believed that the structure of the DE stimulates the digestion and aids in improving feed conversion and absorption of nutrients, essential elements and trace elements. In short, the animal is able to gain more of the available nutrients from the feed you are feeding them. Therefore, it makes economic sense to use DE as a regular addition to your feeding routine.

​External Use

Use as a dust or a spray to control external parasites. To use as a spray mix 250 grams with 4 litres of water and spray livestock - filter before use. Spray and dust around living quarters and bedding.

The following rates are only a suggestion as livestock and pets vary due to the difference in farming procedures and animal size.

Super Fine DE as an Insecticide and Pesticide​

DE is a highly effective organic pesticide, insecticide and fungicide. DE offers protection against disease, fungi, nematode and insect attack but without the negative and often toxic effects sometimes associated with manufactured chemical products. ​

DE is a totally safe organic powder suitable for the control of insect pests around the farm, home, office, factory or warehouse, in fact anywhere insects are a problem. It is so effective that any insect that comes in contact with DE will die in 48 hours or less. It is the formation of the actual Diatoms themselves that are fatal to insect pests rather that it’s chemical composition (as DE is totally nontoxic). The sharp edges of the Diatoms cut the insects exoskeleton and draws moisture from inside the insects – this is call Desiccation (dehydration). DE is not a knockdown because it is not a poison but it does achieve the desired results and is used extensively in the USA and Europe as a method of pest control for many years, and is now readily available in Australia.

​Indoor Use​

Apply a thin layer of dust in any area where pests are found; under skirting boards, sinks, kitchen cabinets, behind and underneath fridges and stoves, laundries.

​Outdoor Use​

Apply liberally around garbage bins, windows and doors, entrance points, garage, sheds and workshops, gardens, fruit trees, veggie patches, pets, pet housing and bedding for the control of common pests in and around the house and garden.

Insect pests controlled include:​

All Ants, Caterpillars, Cutworms, Armyworms, Fleas and Ticks, Bedbugs and Carpet Beetles, Centipedes, Cockroaches, Potato Beetles, Crickets and Earwigs, House flies, Millipede and Mites. Scorpions, Silverfish and Spiders, Scorpions, Slugs and Snails, Lice, Fruit flies and Vinegar Flies, Aphids and Weevils, 12 spotted Cucumber beetle, Green Veggie Bug, Corn Ear worm and Corn Borer, Harlequin Bugs, Leaf Miners and Loppers, Squash Vine Borers, Thrips and White Flies, Peach borer and Pecan Weevil, and Grey Back Cane Grub.

Application Rates​

Dust: as a dry powder until the area is lightly coated with DE

Spray: by mixing 500gms to 5 litres of water, keep agitated and spray the area to be protected. Filter it before use. But remember that DE works best when dry.

As a Barrier: Apply DE in a 10cm border around the property to be protected. This is particularly  important when controlling Fire Ants and Termites.

Remember that the insect must be in contact with the DE for it to be effective. If you spray the DE directly onto the insect the DE must first dry before it begins to take effect.​ So while you may not get an instant result as you would with a knockdown spray the benefit if using a product that in Natural and Organic, safe for you, your family and the environment, makes it all worthwhile.​

Super Fine DE for Oil Absorption and Spill Kits

​Because of DE’s very absorbent properties, consisting of more than 70% silica it is the perfect product to have in your spill kit, house, garage or shed for cleaning up grease and oil spills. Cloth rags, sponges and paper towel often leave behind residue and spread the spill further than the initial mess making the clean-up time twice as long. The porous molecules in DE are able to absorb high quantities of moisture unlike a lot of other cleaning products on the market. Also, DE is 100% natural and nontoxic making it a safe alternative to use in any situation. The Diatomaceous Earth renders the spill inert which neutralises the chemicals in the oil and be safely disposed in the rubbish bin. DE can retain up to 100% of it own weight in liquid.

How to use:

Firstly, act quickly. Apply DE to the spill as soon as you can. Apply up to an 1” over the spill. Leave for approx. 2-24hrs for the DE to absorb the spill. The longer you can leave the DE on the spill the more the DE will absorb the oil or grease. DE can hold more than twice its weight in liquid, so the longer it’s left on the spill the more effective it will be.​

Once the DE has absorbed the spill, simply sweep up with a dustpan and brush and dispose of safely in the rubbish bin. If the spill in on a carpeted area, apply as per above instructions, sweep up the majority of the DE once absorbed and then safely vacuum the finer DE particles. If the spill has caused a stain, simply clean the area with warm, soapy water to remove the mark.

Super Fine DE for Pest control in grain storage

Our DE Super Fine is the finest grade DE currently available in the Australian market. Due to is very fine powder content it controls insect such as weevils, beetles, moth and borers in stored grain such as rice, corn, sorghum, lentils, wheat barely and other stored products. It can provide up to 1-year protection against insect and pests.


  • In storage and warehouse facilities where any food products are stored

  • After harvest apply to machinery, combine harvesters and belt conveyors to avoid any increase in pests during the off season

  • In grain handling operations and in empty silos as a protection method


CAUTION: Do not confuse natural silica or food-grade Diatomaceous Earth with crystalline silica which is commercially produced by exposing amorphous silica to extreme heat for use in swimming pool filtration systems. Crystalline silica is extremely dangerous and must not be consumed by humans or animals, or used on gardens or agricultural crops. All care should be taken when applying DE Dust. The dust particles could irritate lungs and long term use if constantly inhaling could cause potential damage. Additionally protect skin as DE is particularly drying and may affect sensitive skins. Use standard protection as you would when using any insecticide, although DE is non toxic.
