I know, kinda beating a dead horse here, but while I was at work I checked out the labels of the serious flea shampoos, powders, and sprays that you can use on the carpet (and shampoo on the dog/cat). These are the products that most petstores in California probably carry, but I can't say the same for other states.
Cats had only one shampoo, whose active ingredients were Pyriproxyfen-2, Pyrethrins, and N-Octyl bicycloheptane dicarboximide.
Dog products all had essentially the same chemicals:
Pyrethrins
N-Octyl bicycloheptene dicarboximide
Pyripoxyfen
D-li Monene
Piperonyl butoxide
Carbryl
Permethrin
*Tetrachlorvinphos
(S)-Methroprene
D-Trans Allethrin
Di-N-Propyl Islochomeronate
Linalool
All of the products only had a combination of at most 4 of those chemicals. I'm really fuzzy on my organic chemistry (knowing what all those godawful names mean) but most of those compounds look like they're just huge, complex chains of chlorine, oxygen, and carbon.
The only one that looks like it might have phosphorous (or phosphates) is the one I starred, which was in the Hartz brand products.
If anyone's feeling particularly bored at work and would like to add any information about those compounds I'm sure we'd all appreciate it.
I'd check them out but I have a lot to do before classes start tomorrow.
