There's something about the idea of sprinkling Sevin dust in my house that just gives me the heebie-jeebies. I'm also told that sprinkling table salt in the carpet will accomplish the same thing, but I can't recall if I've ever used it--it has been a long time since I've had to fight fleas, and I don't remember if I learned about the salt trick before or after that. I vaguely remember sprinkling salt in the carpet, but it may have been a preventative measure...actually when I was a kid and we had an indoor outdoor cat and fleas sometimes hatched, my granny would sprinkle 7 dust all over the carpet and leave it on for 24 hours and sweep it up. no more fleas. Ive heard the same can be done with plain salt.
