Advantage or Frontline (Frontline kills ticks too) are great for fleas. But as the veterinarian always says, if you don't treat all pets, and their surroundings, you're always going to have a problem. And when you have multiple pets, as I do, that can become quite expensive!

I use Frontline during the warm months on both dogs and both cats. Used to use Advantage exclusively until the ticks found us this spring (can't Frontline myself, but most of the ticks were on me!). I don't have carpet, and only two rugs, so I don't have a big problem indoors, but I did decide to keep the dogs and cats inside and treat my yard with chemicals, which many folks are against. But the ticks were way worse to me than any flea I had ever seen, and I wanted to try to rid our property of them. Haven't seen one since I did that and started them on the Frontline. (Knock on wood! )
