Most people are going to want to prevent it from happening. We don't treat unless we see fleas, but then we notice them rather quickly and things don't get out of control.
Frontline Plus and Interceptor are fine together. If you switched to Sentinel for heartworms (Interceptor with a chitin inhibitor to stop fleas from reproducing), then Advantage would be okay. Frontline Plus can work for ticks, but if you wanted to use Advantage and want tick protection, then it would have to be Advantix (which contains permethrin...which some don't like).
