I don't know all of the snakes in FL but we do have rattle snakes and pygmy rattlers. Also water moccasins and they are aggressive. Pygmy rattlers are aggressive and they will chase you or a pet.

We lived in SE FL and I had a plant right outside the front door on a little table. It started to rain so I told my husband I was going to move the plant to the yard where it could get rained on. He being the gentleman he is offered to do it for me. When he picked the plant up and was carrying it a pygmy rattler jumped out and went after my husband. We were both at the door and it was headed towards the door. We slammed the door shut. My husband went to the garage through the inside of the house and got on the riding mower, and destroyed the snake. At that time we had dogs and we weren't about to take a chance that snake would go after them.

My first time facing this type of snake here in The Villages. Do you know what it is?
 

Had one in my yard recently, believe me, they are more afraid of you then you are of them. I scared the poor thing terribly.

I saw a black snake in the back last year, but it took off before I could really look. And one in the front, also took off real fast. Nevertheless, I bought a cordless blower powerful enough to blow the garage away - just in case one decided to come inside. I don’t have rats, but if I get any I’ll deal with them another way.

That was my experience also with this one, I tried to shoo it away with a stick, and it wasn't budging. Big noise didn't bother it either. I'm glad it finally slithered away! And thanks for the heads up, my tetanus status is up to date.

WHOA that was quite the event!

In Florida, an outdoor cat is a short term cat.

That's a black snake and is a property owner's best friend, in that it normally kills and eats ALL the poisonous snakes around. And it eats LOTS of mice and insects. If your cat was foolish enough to mess with the snake (not likely) the snake, also like any turtle MIGHT (?) BITE the cat on the paw, but black snakes are non-poisonous. Most likely, the snake would RAPIDLY move away from the cat - quicker than the cat could move. State Farm and Black Snakes are "like a good neighbor".
..........If we were in Naples Fl., there could be Boa Constrictors which could kill a cat and eat it.
.........It might NOT be a good idea to let a CAT out at night around TV Land because there are possibilities of alligators in ANY of the lakes. And even a very LARGE snapping turtle could take a hunk out of a Cat

Why would you need a "vacine or antidote" for a NON-venomous snake?

Sometimes you can't make this stuff up!

Poisonous Snakes in TV.
 

Coral Snakes are also present. Had a couple of sightings a couple of years ago in our hood. They are VERY dangerous and have a mean venom. Have never heard of anyone or anything actually being bitten by one however. Like most snakes, they don't seek out trouble. They are very colorful so are easy to see.

They are quick. My first experience with one was when I was walking along an MMP. I heard a commotion in the brush next to me and a Black Racer came bounding (literally...they move FAST) out of the undergrowth. He saw me, slammed on the brakes, spun around and took off in the opposite direction. Must have been chasing something.

Snakes are cold-blooded. At 40 degrees or less they don't like to move fast - sometimes staying coiled up - that is when people step on rattlesnakes the most. A black snake at 80 degrees would probably beat most runners in a 100-yard dash if they could be coerced into running straight.

A tetanus shot is used to prevent problems from cuts on rusty steel and iron object. Also if a dog bites you. Has nothing to do with snakes. For Poisonous snakes (except the CORAL SNAKE which has a nerve agent poisoning) you need to make a cut at the bite and then SUCK it out. You spit it out, but it can't hurt you in the stomach because of stomach acids. For a CORRAL snake you need to get a person to medical attention quickly, they have an antidote. There is a snake from India (I think) called a 3 stepper that kills people quicker than the CORAL snake. But the Coral snake is Florida's most poisonous snake, worse than a rattler, water moccsin, or a copperhead.
..........Now, I suggest that I am NOT AN ENCYCLOPEDIA about snakes. So, for more information trust your Google Machine the MOST.

The Coral is far from the most poisonous Florida snake.
You should try the google machine yourself.

Coral snake anti-venom hasn't been made since 2003
If coral snake bites you, don't count on antivenin

The cut and suck out the venom is not recommended according to the CDC

Great advice. You should take it...

Spoiler alert: The answer is no... It's complete nonsense, promoted by the old cowboy movies... And it'll probably make things worse...
