Diatomaceous earth - good or bad?


I recently rescued a Persian male about 6 months old and he is a flea bag! I have bathed him twice in Dawn and massaged it in really well for more than 15 minutes and combed out as many fleas as I could find. I have also treated him with Advantage and I still seem to find "flea dirt" on him. Not to mention, I vacuum everyday just in case there are any pregnant fleas laying eggs around my house.

I also have another kitten about 12-weeks old who I gave Advantage and she seem perfectly clean.

I have been reading about diatomaceous earth and I am wondering if anyone here has experience with it as a flea killer and de-wormer. I would like to dust both cats with it and my baseboards - if it is truly safe. I would also like to feed 1/2 teaspoon to the kittens every day for 3 months as a de-wormer. I know it is hazardous to inhale, which is the only drawback that I can find. Just curious if anyone has actually used it and what they think.

I also have 3 small children under 5, so I don't like to use chemicals in our home. If you have any other fool proof, non-toxic way to keep fleas off of hairy cats, I would love to hear them.

Re: Diatomaceous earth - good or bad?

Not to disturb you, after all this time after your question about DE, but I would share the one little thing I know about it.

DE is like big crystal sharp boulders to little tiny bugs like mites and I suppose, fleas, too. It cuts their bodies and kills them. (a good thing!) So dusting carpet, baseboards, doorways, windowsills, etc. may work. If the DE gets wet, you will have to re-apply.

However I do not know how cats would be affected by licking or breathing it.

Hope you are rid of the critters by now and don't even need to read this!

PS: My furs wore bandanna collars containing eucalyptus (sp?) and another herb (can't remember the name) all the terrible Summer of the Fleas here in 1997 and never "re-caught" fleas. They go outside on ropes but only on the cement. --

Re: Diatomaceous earth - good or bad?

I remember we had a discussion about DE not too long ago, though I can't remember whether it was here or somewhere else. The conclusion coming out of that discussion was that DE is safe to use so long as you use human grade DE. The other kind, used to deter ants and other insects is the kind referred to in the post above. That is NOT.

Yep human grade is just fine. My understanding is you can even feed it to your pets--although I don't plan on doing that.

It sounds like DE can be a PREVENTATIVE, too...
