Along with treating my kits with the DE, I also sprinkled the
Earth on Rugs and floors and then vacuumed every day without fail, emptying the bags
on the vacuum quite a few times to keep from blowing eggs and larva and fleas back into the parts I already vacuumed. I did apply the DE right to my cats fur, not near the faces or ears at all, when I saw them scratching and the DE does not outright kill the fleas, but dries them up and then they die.
