They sell big bags of diatomaceous earth at pool supply places. It is
pure unlike what you get at nurseries - they put clay in it for some
reason.

I think it is less than 50 cents a pound but you have to get a big bag
of it. It has a long shelf life.

This is NOT the same type of D.E. as the horticultural and food grade D.E. Pool
D.E. is chemically heated and the properties are useless to soils, and certainly
not edible, and nothing to breath in.

I buy D.E. (horticultural/food grade) at Lowes. They have the brand name
"Concern." Never use pool D.E. as you would the proper material.
