Would you recommend Pyrethrin Dust over Diatomaceous Earth powder or are they pretty much the same thing?
While they are actually very different products, they do pretty much the same job. Pyganic dust is made from pyrethrins and silica gel and MotherEarth D is diatomaceous earth (crushed diatoms). Pyganic dust would need to be reapplied every 6-8 months while MotherEarth D would only need to be reapplied if it were to get wet. Pyganic dust does have a bit of a faster knockdown.
