  I'd say you can give the Comfortis the next day.  Comfortis is great you can buy a larger dose and cut it up.  I've had three vets tell me this, always consult your vet before doing this thou.  Although I am all about a holistic approach I live in Florida and lets get real.  These bugs would survive an atomic bomb.
