Hi,

I buy my diatomaceous earth (DE), at the feed store.  It cost $19.95 for 50
lb of food grade DE.   I use it on weevils in grain, in the goat's loose
mineral mixture (for worms), on ant beds, dust the dogs for ticks and fleas
and to dust the garden without poisonous chemicals.  It looks like sharp
glass under an electron microscope.  Lots more information on the internet
and this is my favorite mined product, made from diatoms.  Can't find
anything better in my opinion.  Do NOT confuse the pool type of DE with food
grade because the pool type has been heated and is ineffective for the above
things.
