Frontline not working on fleas
We have had a bad flea outbreak in Fl and Frontline dosen't seem to be
working any longer. We had ordered some off the internet awhile back and the expiration date in in 2005. Put it on both cats as prescribed about two weeks ago and so far, no effect on the fleas. Therefore, 1) Are fleas developing a resistance to FL? or.. 2) Could this be a defective batch (even though not expired)? Just wondering what to try next but wanted FL also for the tick benefit. thanks-- |

I then switched to Frontline and it worked. Perhaps fleas in Florida have developed a resistance to Advantage? I suggest trying a different brand. I really think these companies should change their formula every year as fleas are becoming resistant. |

Use a spray or bomb with an insect growth regulator. Vacuum daily and throw away the bag. |

It's poison I tell ya, poison! Which is not to say that I don't use it myself... --Catherine & Rosalie the calicohead |

If you spill too much of it into the fur, it won't work very well. Advantage works exactly the same way (same formula). Your home/cats' environment might also be infested. Frontline doesn't kill flea eggs or larvae, so if the cats sleep or lie where there are flea eggs or larvae - they'll become infested again and the cycle begins again until those fleas die off. This could give the appearance of the drug losing efficacy. Also, are your cats exposed to other cats or dogs or possibly infested environments? If so, you could have a reinfestation problem. Treating the cat is only one part of getting rid of fleas. You need to treat the environment, too, and also prevent reinfestation. Good luck. Phil |
