Yes, snake boots would be a neccesity here. I have only lived here ( south west GA) for about 14 months and have seen 12-13 rattle snakes, 2-3 moaccasins and countless non venomous species. Even in winter months the temp doesn't drop below 60's in the day. Probably 5 out of 12- 13 rattlers were seen in Oct - Dec range. Though they were not really responsive they were out of the ground. We actually have a festival here in Jan. called the "Rattle Snake round up" I hope this was of some help to you.
Absolutely needed and necessary.
As waltor stated it doesn't get cold enough for them to completely stop moving about. Those Cottonmouths can be really aggressive and will come looking for trouble.
If you will be wading thru water or easing along swamp edges I would go a step farther and get some snake proof chaps as well and watch your hands, most snake bites are to the hand/forearm area.
First make sure your gun is safe, remove the bolt and clean your barrel from the chamber to the end of muzzle. Clean the barrel using butchers bore shine until a patch comes out white. Run a total of 5 separate patches soaked with denatured alcohol through the bore and let dry for 30 minutes. Insert a cleaning rod with a jag and a dry patch into the neck of the chamber. Make sure it will stay there through the next process. Now using another cleaning rod, install a patch that has been coated...
