Yeah, that's my preference too. I had a shitty roommate that brought home a flea-invested cat. We spent weeks trying different sprays, powders, shampoos, bug bombs, etc. They just kept coming back.
Finally got a bag of DE and dusted the house. You could watch the fleas come out of the carpet and die in seconds. They were completely gone overnight.
Cheap, easy, kills any insect it touches, and it's mostly safe. Just try not to breathe it in.
