Diatomaceous earth to treat fleas?

[binka_nugget]

I treated the three with one dose of advantage and spread diatomaceous earth on the carpet all over.. seems to have worked!

[So-Crafty]

I had gone through flea shampoos, topical gels like Frontline and Advantage, flea collars, flea combs. I had such an infestation in my house that nothing. worked. But they are gone now.

My secret? I treated the source before I treated the animals. I used a Borax/Salt combo on the carpets and vacuumed up about 12 hours later. Then, I religiously killed any fleas on the animals with natural sprays. I retreated the carpet 2 times a week for 14 days, 1 time a week for 21 days and then now I'm up to every 6 months as a precaution. I haven't had a flea since.
