Diatomaceous Earth 'N' Natural Products Out West started out of a desire to bring to Western Canada nature's natural gifts and reduce the chemical ingestion/absorption of our animals and ourselves.   One amazing organic natural product is Diatomaceous Earth. It is know for many benefits but is sold as an anti-caking agent. No information on pests elimination is claimed, however, please refer to  wolfcreekranch1.tripod.com/no_flea.html

a natural dewormer for livestock (no reason for rotation because it is known to act by physical action not chemical..therefore no immunity developed) and an animals and human detoxifier is another known possible benefit of D.E. We believe that "Nature's Way is the Only Way" and we try to adhere to her rules as much as possible!
