In Fla, as with everywhere else, it is NOT illegal to kill a venomous snake if:
it posed an immediate threat
has bitten someone or pet or livestock
in a dwelling
They would not respond unless it was in the home because of simple mathmatics. If they responded to every snake/wild animal call received, the entire population of Fla would be working for the animal control. They receive thousands of calls everyday.
If a snake, venomous or not, is on your property, leave it alone. It will go its way. NEVER attempt to capture it or harrass it. This could result in a fast trip to the slow wait of your local ER, or worse.
If this is a pest issue, contact a pet store. They will most likely know who will come get it for free, and you'll know the snake is gonna live.
