My rule is if it's harmless leave it alone. Leave the door open and it will leave eventually. We have species of poisonous snakes here in Florida. I have taught my wife and son what they look like. Although two of thee 6 are found in the northern part of the state. In our area we mainly get pigmy rattlers, eastern diamond backs ( saw a monster a few weeks ago crossing the road. bout a 6-7 footer), water mocs, and your basic coral snake. Saw my first pigmy about 6 months ago. Was in the garage. I caught it with a pair of plyers to show the kid. Haven't seen a coral in many months. But we have tons of black racers, indgos, rat snakes of all colors, and a ring neck that I have just started seeing.
I'll add one funny story. I was helping my younger sister clean out her tack room in her stable several years ago. It was early spring. Still relativley cool but sunny. She went to reach for a "coil of rope". Just before she picked it up I realized it was a 4-5 foot brown rat snake. She picked it up, dropped the snake, ran one way and the snake the other. I naturally stood there laughing my a$$ off .... LOL
