Where can I buy fresh water food grade diatomaceous earth in Houston TX Area? I want to use it as a wormer for my horses and dogs. Thanks.

I buy food grade diatomacious earth at the feed store. Delilah500 is right. Absolutely do not use the DE meant for swimming pool filters for your animals.

Fresh water food grade diatomaceous earth is unlike other forms of DE because it is safe to pets and people. This is for information.. not a cheap plug. You can also buy food grade diatomaceous earth inexpensively ONLINE. I own a company called Earth Works Health, and we distribute Permaguard Fresh Water Food Grade DE products with the best prices on the net. You can find us at Earthworkshealth.com.

I don't think the Diatomaceous Earth that you're seeking is the same that is used in swimming pools.
I would check with the health food store or a vet before giving it to any animal.

Jean, I don't know anything about your question but just wanted to say HI cause I'm from SEALY-hi again.

Hope you have found it by Now! I use on my horses, cats, and birds. My birds include Dom. Turkey, Wild Turkey, Pigeons, Jersey Giant Chickens, One Emu, and a Chukar (Used to have Pheasant, Quail, & Peacock, Toned down a little). Birds get it in their food, nest boxes, sand (dusting) Boxes, Horses get it in their food and I sprinkle it on the floor to cut down on oders, and cats get in their food sprinkled on them for fleas etc. I've been using it for 10 years! Any way you can find it just about anywhere out west by the fifty lbs. bag. One place is wolfcreekranch.net in CA. Do your research! It has to be food grade, and don't buy anything that sits on a shelf in a garden shop near poison. I live in Upstate NY Its $30.00 to ship it here!
Where can I find Diatomaceous Earth?
Go to any swimming pool supply store.
We used it to put around our flowers and plants that slugs love, it stopped them in their tracks. I'm reading that it is good for other pests as well.
I buy it at the nursery, but before I could get it locally I bought it on-line. I buy the 25 lb. bag. (07/12/2004)
Diatomaceous Earth is used in some types of swimming pool filters, therefore it is readily available at swimming pool supply dealers. (07/12/2004)
They sell it at health food stores with the pet supplies. (07/12/2004)
Home Depot has it, check the garden department. They did warn us that it also kills the good bugs such as earthworms. We decided not to use it. (07/13/2004)
I didn't know it killed the good bugs, thanks for the info. But I just sprinkle it on ant hills & around the perimeter of the outside of my house. I haven't seen any dead good bugs or worms. It's also one of the few things you can use inside safely. (07/13/2004)
Warning! I just read on another site that you don't want to use diatomaceous earth that is for swimming pools: "DE sold for swimming pool filters is ineffective for insect control because it has been heated and chemically treated. It won't kill insects and it is very dangerous to breathe."
Also, if you are using DE for garden insect control, be careful, because it will kill beneficial insects too! Don't use it too often. (07/19/2004)
You should not use swimming pool DE. It is heat-treated, which causes a change to the powder that makes it more dangerous for humans. See: http://en.wikipedia.org/wiki/Diatomaceous_earth
dirtworks.net has diatomaceous earth - you can buy the freshwater, food grade, it comes in small or large quanities, along with puffer bottles for insect control. (10/14/2006)
sorry, here's the link:
I'm going to go buy some at home depot. (12/30/2006)
You can use "beneficial nematodes" for the yard. I read that they eat the larvae of bad insects, not the good ones. I'm planning on using that in the yard and DE in the house! (01/18/2007)
Is diatomaceous earth readily available in Central Mexico? Is it a locally produced material, or must it be imported?
Editor's Note: The Aztecs used to use it so it must be available in Mexico.
WARNING: Please make sure you distinguish the difference between
"Food Grade Diatomaceous Earth" and "Pool Grade Diatomaceous Earth".
Food-grade Diatomaceous earth is safe to use around pets and children and indoors with animals, while pool grade is toxic to pets and even humans!
You can buy food grade diatomaceous earth online at:
Or retail stores:
If you can find a retailer near you, the best place to find "food grade" diatomaceous earth is at a feed store.

Make sure that if you plan on ingesting diatomaceous earth, that it is labeled as "food grade". Otherwise, it is larger shards and can tear at the intestinal lining. (02/01/2009)
