I use Interceptor only from May to Nov.
Last May we got our yard treated for ticks and they didn't get any on them at all last year, so I was able to stop using Frontline, as I am not thrilled about putting a chemical like that on them. We don't have fleas so I don't have to worry.
I did just buy that stuff from Only Natural along with the S & C - so I hope to have success again this year
