deerhuntress, there is an Advantix spray. Last summer my then 1 1/2 yr. old Springer got a terrible case of fleas. He had just received his "summer clip" two days prior and we thought maybe he got them when he was being groomed. That was not the case. He had so many fleas we had to take him to the Vet at once. She gave him a treatment of Advantix spray and said to give him another treatment of standard Advantix after 24 hrs. One day later he had no fleas at all. When asked what could have caused this problem, she said he probably ran into a "storm" of fleas in the woods. I was very impressed with the fact that he had few fleas on him and those were dead. He now takes his Advantix every 3 weeks instead of four and the folks at Advantix paid for a yr. supply. We feel this was a very rare situation. Since (and before), while using Advantix, he has never had a flea, mosquito or tick on him.
