The rut in Fla can be from Sept to Feb depending on where you are in the state.
South Fla is usually earlier and North Fla.

As far as rattling, never had any luck with it. I just like to find an active scrape and set up on it, and wait for a big buck to check it. Hunting scrapes can be very productive, here are a few tips.
Do not get to close to the scrape, shooting range and where you have a clear view.
Watch your scent and wind direction, when you can.
Get a comfortable stand and sit all day , or as long as you can.
Sneak in early and be as quite and use as little light as possible.
I do not use Deer scent to attract the deer: but, I use a buck bomb, just to mask my scent. ( never really had much luck with deer scents either)
