I was wondering if anyone could tell me where to buy diamateous earth please? I live in Portland so there are tons of pet stores / health stores / med stores, etc etc. Online it says "any local health food store" - but does this mean like GNC? Or could I find it in, say, the health-food isle at Whole Foods? I just don't want to drive all over the place, all the specialty stores are pretty spread out.
And second question: How much does it cost for how much? I often end up buying too little of a home-remedy flea product. Like $__ would cover my dog and his bedding ___ times? Thank you so much for any help and advice on using diamateous earth, and sorry in advance if "this question has already been asked".
