Diatomaceous Earth - Part 3 - Uses for Pets and Livestock

Article addressing the use of diatomaceous earth for farm animals and pets health.

Diatomaceous Earth (DE), as discussed in parts 1 and 2 of this series, is organic and is a mineral.  Previous articles discussed how this product could be used to get rid of bed bugs and used for lawn and garden pest control.  While diatomaceous earth is very harmful to insects and some types of fungi, it will have no harm for humans or pets.  There are no chemicals used at all.  Diatomaceous earth kills the insects by breaking or piercing their outer shell which then causes the insect to dehydrate.  The product is a fine white powder which insects also carry back to their colony.

The uses for pets are for flea control, ear mites, wormer, dietary supplement, and ticks.  Diatomaceous earth comes in two grades – regular and food grade.  While neither grade is harmful to humans, animals, or plants, it is recommended that food grade be used on and around animals because it is more refined.

For pets, to use as a daily food supplement or as a safe wormer, mix with pet food in these quantities:

Mini Dogs – ½ teaspoon

Dogs under 50 lbs. – 1 teaspoon

Dogs 50 to 100 lbs. – 1 tablespoon

Dogs 100 + lbs – 1 to 2 tablespoons

Kittens – ¼ teaspoon

Large Cats – 1 teaspoon

Diatomaceous earth can be sprinkled in your pet’s living area by applying to moist areas to reduce odors and dry the area.  It will stop fleas and ticks from breeding.  Add to cat letter to control dampness and odors.

For older dogs and cats, diatomaceous earth added to their food also helps reduce inflammation caused by arthritis.

Speaking for a particular supplier of Diatomaceous Earth, Veterinary naturopaths and hosts of the online radio show, Animal Talk Naturally, Drs. Kim Bloomer & Jeannie Thomason, www.animaltalknaturally.com, have this to say about (Permaguard Brand) Diatomaceous Earth:  

Our work is based on natural, preventive care for animals so of course we are always on the lookout for good, quality NATURAL products to help our clients and our listening audience that won't break the bank. We've long been proponents of FOOD-grade diatomaceous earth as a natural pest control for both external and internal use in animals. Earth Works Health has provided the high quality and affordability of DE in their Permaguard product that we look for, both for our own personal use as well as for our clients.

Livestock, including chickens, horses, goats, pigs, cattle, etc. have been observed to benefit in these ways from

DE:  flea and tick control, stimulated metabolism, better feed conversion, correcting and preventing scouring or diarrhea, reduced odor in barns and stalls, improved hoof and coat, fly control, mastitis control, improved egg production, prevents algae overgrowth in livestock water.   Application amounts and methods for particular livestock animals can be learned from the distributor of the products.
