Another Diatromaceous Earth question

Hi there and welcome Jason! I use D.E. FOOD GRADE only. I will continue to use it as I use it to keep my coop/chickens clear of mites, etc. Odor is just a side benefit for me. I, too, use deep litter method. I put the D.E. in their "dust bowls", nests and under all the litter when I clean out the coop. There is always dust when you work that litter in the coop so it is best to cover your mouth to be on the safe side anyway. Many old timers never used D.E. as they didn't have access to it long ago and I am sure many do not use it now but why risk having mites in the coop and on your chickens?? That is what would rule my decision. Again, this is just my opinion.

Origins of Diatomaceous Earth
With more than 600 deposits of diatomite west of the Mississippi—and only four (to our knowledge) that can be considered food grade—it is very important that people know what they are using. The vast majority of diatomite deposits are impure.



When diatomite is formed, water currents bring in foreign material that mixes with the microscopic diatom shells. This type of diatomite is absolutely without value for practical purposes, but many people tend to think that if it is “Diatomaceous Earth,” then it has the same value as other, purer deposits. There are many places where diatomite deposits can be loaded up “for free,” but generally this substance has no value. If this impure diatomite is sold for practical usage, the customer may end up with an unpleasant surprise.

Scientists estimate that there may be as many as 12,000 species of Diatoms, each identifiable by their delicate, ornate shells. Diatoms are a dominant species of phytoplankton, ... This fine, crumbly substance is used in insulating materials, abrasives, ceramics, and in filtering and filling materials. More than 270,000 metric tons of it are extracted annually from a quarry near Lompoc, California.

Diatomaceous Earth comes in at least two grades: Horticultural Grade and Food Grade. It's important to use only Food Grade Diatomaceous Earth if you're using it to store grains. If you want to use it on plants, don't get any on the flowers. It'll slice up the few honeybees we have left. And I don't recommend incorporating mass quantities into the soil. Earthworms are good things: You don't want to hurt them until you put 'em on your fishhook. Diatomaceous Earth is also effective against fleas, but again, take care not to let your pet breathe it.

 

is the food grade DE different from the type that is mentioned above as somewhat dangerous to breath? (I realize that it mentions “industrial” form, which is probably different than the food grade form…right?)

Assuming labelling is accurate, food-grade DE contains next to no crystalline silica, which is the stuff that is really rather dangerous to breathe and causes silicosis etc.

I know of no reason to believe that food-grade DE is worse than any other typical dust, like road dust -- you don't want to breathe gratuitous amounts of it but assuming you behave sensibly you'll be fine (barring some individuals with preexisting respiratory problems, perhaps).

Here is a link to a copy of the MSDS sheet for food-grade DE:

For comparison, here is a link to a copy of same for baking soda:
http://www.jtbaker.com/msds/englishhtml/s2954.htm

Not much difference. It is better not to breathe *either one*, but neither is particularly dangerous.

-Why not just use baking soda?

Baking soda seems a slightly odd choice. It is expensive (unless you have an industrial type source), and will weird out the pH of your coop cleanings if you have any substantial amount in there, which you'd want to *check* how the composted results will affect your garden.

PLUS, baking soda will not do much of anything vs mites and lice.... which is probably the most popular and (IMO) reasonable use to which DE is put.

There are plenty of alternatives for odor control: more ventilation, better hygeine, drier run, droppings boards, and if all else fails it'd be cheaper to use zeolite/clay type stall powders such as Sweet PDZ or Stable Boy.

For mite/lice treatment, though, your alternatives to DE are limited to things like Sevin or Rotenone, both of which are unarguably worse for you (although still not *tremendously* toxic pesticides). So I believe there is something to be said for DE as a treatment for lice/mites.

Why did the only two people, who have surely never met, give me the same reasons not to use DE, and yet, this forum goes on and on that it’s the best thing to use?

There is actually quite a diversity of opinions on BYC about whether or how to use DE.

Yes, there is a popular 'bandwagon' as well, but you get that sort of thing happening any time you get a bunch of people hanging out together, esp if many are relative newbies. <Shrug>.

So, do some reading, and thinking, and form your own opinions

Good luck, have fun,

I use DE and Have no problems with it. I use hay in the coop and use DE in both the nests and on the hay, I also rub a heavy handful on the roost when I clean out the hay. You might try to Google golden blend and see if they have a rep in your area. I buy mine from a man who sells exotic bird food and so I don't have to pay shipping, And I pay $20.00 for a 50 lb bag, so I know its FOOD GRADE. . & welcome marrie

 

I've had problems finding DE in columbus OH so I contacted OSU because they have an agricultural department. I figured they would be the best to tell me where to get it and if I should be worried or not.

You might want to do the same thing find a college and ask them.

 

I find that food-grade DE is exceptionally good, and the poultry feed I buy is 5% DE by weight. Birds are thriving and I had 12 eggs from 12 hens today. But if it bothers you why not use a product like Stable Boy or Stall-Dri designed for all kinds of animal stalls?

I've also used Stable Boy for years with horses and I mix it with food-grade DE in my coop.

 

There is a fantastic natural outlet for natural and organic fertilizers and other products. I have purchased food grade DE from them.
Their prices are good.

No kind of dust is healthy to breathe. It's a good idea to slightly dampen what you are fluffing and wear a mask. The chickens "do dust" naturally so who knows if it will bother them, but I would agree that the sharp silica should not be inhaled by man nor beast. It is great parasite control though. Not the ideal thing for a deodorizer, the benefit would be coming from the dryness.

Has anyone heard of using wood ash for dust baths? ...okay, cooled wood ash of course, not trying to pre-cook my chickens!

 

We use DE and it works great for us. Helps absorb moisture and keep bugs out. The food grade DE is basically crushed up fossils; completely organic and safe for us, the birds, and pets. In fact, it's great to pour in your feed storage bins to prevent bugs from getting in and eating/contaminating the feed. No dust is good dust to breathe, but it shouldn't cause much problem unless you use gobs and gobs of it at once.
Just remember that once it gets wet, it loses effectiveness as far as bug killing goes. So you'd need to put out some fresh DE every once in a while.
There is the DE they put in pools (NOT food grade of course), which is harmful, so don't get confused!
