Caution; It MUST be food grade, the type used for pool filtering is lethal. Putting DE powder on your animals and around the home will penetrate the hard shell of a flea, dehydrate it, therefore killing the flea. It can be used outside, in the doghouse, kennel, pen, entryways, etc.
This is best used as a prevention. It doesn't work well if you are infested with fleas. DE can be sprinkled on food as a dog wormer also. Quite often when you have fleas, the dogs will have worms from ingesting the fleas.

I would be very cautious about using DE around pets. I bought some and my cat died. I can't be sure if that is what caused it, but I think it was. I ordered it online and it came in a plastic bag. It was supposed to be food grade, but who knows if it really was. I would rather have the fleas and my cat back. Just a warning. Be careful what you use around your pets.
