I did not have any luck with Frontline. I have used Advantix and Vectra 3d. I think both have been good. I have also heard that Dawn dish washing liquid will kill fleas. I haven't had a problem with fleas but remember hearing that Dawn works I think. We have ticks we battle and Frontline is like candy to them. Lol. I also think there was a natural flea mixture here on YT that was posted. I'm so sorry I don't remember what thread it was from. |
