for its extremely pure quality of Diatomaceous Earth (DE), Perma-Guard
DE is an eco-friendly naturally organic material from the purest fresh
water source. Diatomaceous Earth is the fossilized remains of
microscopic shells created by one-celled plants called Diatoms. Not all
deposits of diatomaceous earth or the diatoms present in those deposits
are the same. The shape of the diatom must be tubular with holes on the
walls. It is important to have a consistent shape diatom without any
unwanted sediment and it must be fresh water because the diatoms form a
harder shell and is less fragile than those in salt water. Salt-water
deposits contain a mix of diatom species. These deposits shapes and
sediments are inconsistent, making them unusable for our products. Of
the 600 deposits in the US only four are considered "food grade" by FDA
standards. Other food grade deposits may contain higher amounts of
sediment and clay that make them less effective. After analyzing many
other "Food Grade" deposits we are satisfied that Perma-Guard Fossil
Shell Flour is the purest form of diatomaceous earth.
Important! Do not
confuse our products with the Diatomaceous Earth
(DE) that is used in
swimming pool filters! This type can harm you and your animals because of
the different processing. The pool grade
DE is chemically treated and partially melted and consequently contains
crystalline silica which can be a respiratory hazard. (see safety

your own experience and the weight of the animal.
- Our DE is GRAS
(Generally Regarded as Safe by the FDA), so there is no harm of
overdose. A basic rule of thumb is 2% of the dry weight of the food but here are some "dosage" guidelines:
Humans 1 heaping teaspoon stirred in cup of water,
mixed in food or in
anything you like.
Children 1/2 to 1 level teaspoon per day.
- Kittens 1/2 teaspoon
Cats 1/2 to 1 teaspoon
- Puppies 1/2 to 1 teaspoon
- Dogs under 50 lbs. 2 teaspoons
Dogs over 50 lbs. 1 tablespoon
Dogs over 100 lbs. 2 tablespoons
- Cattle 2% by weight of dry ration
Calves 4 grams in morning
Dairy Cows 2% by weight of dry ration (4 oz. )
- Chickens 5% in feed, also add to dusting boxes
- Goats 1% to 2% in grain
- Hogs 2% of weight in feed ration
- Horses 1/2 - 1 cup in daily ration
- Sheep 1% to 2% in ground grain
For effective use, the DE must be fed long enough to
catch all the newly hatching eggs or cycling through the
lungs and back to the stomach. A minimum of 60 days is suggested at 2%
of dry weight of the grain ration. It doesn't have to be exact.
More will not be harmful, but less may not give you the
For large animals, DE may also be offered "free choice" as long as
dispenser is protected from wind.
Use on beddings, rub into fur and mix in with salt
and or minerals for livestock
