I have lived in Florida my entire life, 56 years, and spent the vast majority of it outdoors, I grew up in an isolated country house and played all day everyday in the woods, spent 8 years in the Boy Scouts, camping and hiking all over Florida, Joined the reserves and spent 6 years in a Recon Platoon, training, crawling about in the Florida swamps and woods, often at night, and since I was 12 hunted every thing legal all over the state of Florida in every terrain under every condition.
And for the last 24 years I have served as Paid Professional Firefighter and have fought hundreds of brush fires, charging towards the fire in the woods while everything in the woods was charging out.
Most of my friends hunt, one of my best friends is member Gatorgrabber, who is a biologist who specializes in Florida reptiles, he has captured for various reasons, countless Florida snakes and alligators.
In all of that time and experience, I have personally known exactly ZERO proven snake or alligator bites in the wild.
They are exceedingly rare, which is why the ones that do occur receive great media fanfare.
I did have one friend who was bitten by something, which we suspect was a water moccasin ( Venomous snake) through the top of his shoe in the water while beaching a boat. But the snake was never seen, and he was not envenomed, just two painful pokes in his foot.
One of our medics was bitten by a shark while fishing at the beach, a much more common occurrence.
Alligators are common, but shy and skittish for the most part, and try to stay clear of people, as are snakes, which are rarely seen.
Don't worry about snakes and alligators. Don't swim at night in wild water.
