Human Flea Repellant?

[SzczerbiakManiac]

It's my understanding the cats have some kind of flea protection. (Advantage or something like that) I'm looking for a flea-equivalent of mosquito repellant that will keep the vile little buggers off of me.

I've contemplated putting plastic bags over my feet & legs before entering. If there isn't an effective chemical solution, I may have to go with that.
