I have used a spray that contains a ingredient called Ovatrol, it doesn't kill the fleas but makes them sterile. The spray also contains pyretherem (sp?), an extract of African daisy that is an insecticide. The fleas on the animal are killed but the ones that hop on later are sterile when they reproduce, thus breaking the breeding cycle. We literally have gone years between flea outbreaks and our cats and dogs are outdoors animals the cats hunt also.
I swear by this stuff, I have had cats that were killed by the internal and dermal treatments such as frontline.
