What is Diatomaceous Earth?

Diatomaceous earth is a remarkable, all-natural product made from tiny fossilized water plants or algae. Diatomaceous earth is a naturally occurring siliceous sedimentary mineral compound from microscopic skeletal remains of unicellular algae-like plants called diatoms. These plants have been part of the earth’s ecology since prehistoric times. It is believed that 30 million years ago the diatoms built up into deep, chalky deposits of diatomite. The super-fine diatoms are mined and ground up to render a powder that looks and feels like talcum powder. The coarse ground is less dusty and looks like fine gravel consistency. DE is approximately 3% magnesium, 88% silicon, 3% calcium, 3% sodium, 2% iron and many other trace minerals such as titanium, boron, manganese, copper and zirconium.

Organic Food Grade Diatomaceous Earth is a natural (not calcined or flux calcined) compound.

Superfine diatomaceous earth (<0.3mm) may be used for feeding to animals, dusting through animal’s coat or dusting house for pest control.

Coarse ground diatomaceous earth (0.9-2mm) may be used for feeding to livestock or poultry, dusting pens, greenhouse or outdoors on fruits, vegetables, flowers, grains and grass, up to and including the day of harvest.

    Hi, I purchased this product from you and have been using it for several months now on my poultry. I dust them with this and also put some in their seed and sprinkle it around the hen house.

    None of my birds have lice and it is great product. Delivery was prompt.

    I use this for pups and kittens. Just add a bit to their food each day for a month or so and this will break the cycle. I also add it to the birds’ seed and rabbit’s food.

    Also can be used on carpets – just don’t use too much or you’ll block the filters on your vacuum cleaner.

    I finally found a product that kills fleas on cats and dogs SAFELY. Over the years, I’ve become anxious about using chemical products, as it only takes one time for your precious pet to have a bad reaction. Plus I’ve witnessed alive fleas on my pet 2 days after applying the expensive chemical product.

    I did a lot of research into looking for a safe and effective treatment, and I read numerous times, about applying Diatomaceous Earth. I even watched video clips on UTube about it. I would rather not put it heavily on my cats long hair, as I want to avoid the dust that can come off it, from doing this. So I simply put about a teaspoonful of the powder into my hand, (I buy the extra fine powder from Greenpet) and I lightly sprinkle it onto my cat’s coat, and then simply give her nice long pats, and she doesn’t suspect a thing ha ha ha. This way I avoid the powder being dusty in the air. I’ve picked a flea off her an hour later, and it can’t even hop. The flea wobbles around as if it’s drunk before dying. I’ve poured out some of the Diatomaceous Earth into a smaller container, and every couple of days I do the exact same thing.

    One man on UTube shows putting it on his cat a lot more heavy then what I do, and he protects his cat’s face from the dust in the funniest manner. I ordered this on a Thursday, and it turned up the next day, Friday. I did pay for Express Postage, but this is still fast, considering Greenpet is in Queensland, and I’m in Canberra. I even give my cat half a teaspoon a day mixed in her food, as it’s also effective in killing worms in cats and dogs very safely, plus it gives them so much energy. You end up with a very happy pet. All animals can use it, including horses and cattle. And I bought a huge 2.5kg bag, and it was only 23 dollars, so I’m very happy, and so is my precious cat. Thankyou Greenpet.

    I bought this product to de flea my house. it was very effective as I noticed dead fleas on the carpet the following day. It is so much better to use a product which is harmless to my pets and to me, rather than using harsh chemicals

    I was astonished when my order arrived within a day. Good quality and great service

  6. Christine S. (verified owner)

    Greenpet products are excellent and this one is too. My cats do not need flea prevention when I use this on the lawn in the backyard and it does not harm the plants. It keeps unwanted fleas away in their play enclosure as well.

    The item took nearly three weeks to arrive but the wonderful customer service and follow up was second to none

      Sorry that your order took so long to arrive but unfortunately due to the bush fires and holiday period, the couriers where taking much longer than usual. Hopefully future orders will not take this long.

    I use it as a natural pesticide for my houseplants and it works a treat.

    I also ordered this during the Christmas period and was pleasantly surprised that it came so promptly. Thanks for your hard work!

  11. Chin (verified owner)

    I put this in my garden so my cats won’t get the fleas from the garden. So far, it has worked.

    I had the WORST flea infestation. My poor animals were constantly itching, and it seemed that nothing was working to help them! Until I grabbed some of Greenpet’s Diatomaceous Earth! I treated my house and pets once a week for 4 weeks, and now it’s like we’ve never had fleas before! Great product, will 10/10 purchase again if needed!
