You don't generally see Brown Recluse spiders in Florida, but they are quite common in Texas where I am from. They are very bland looking,, deceptively so.

As far as I know, the cute little frogs in Florida are safe. It's the tree frogs that have poison on their skin, none in Florida, as far as I know.
Major 'YIKES' factor of 10 about the black widow spiders! Professional for sure.
About scorpians, we spent a holiday in a cabin in the Texas Hill country a few years back, and my youngest DD, (who was about 6 at the time) put on her water shoes that were drying out on the front porch. Seconds later, she was screaming her head off, and upon taking off her watershoes,, a scorpian fell out. Well, I guess we had seen way too many Cowboy movies,, as we panicked big time. We were out about 50 miles from a hospital, so we drove to the owner of the cabin, who calmed our fears, and told us to put wet baking soda on the sting, and have her keep her foot in cold water, at the creek possibly. Sheesh. She always shakes out her watershoes now, and remembers vividly that scorpian. She believes it targeted her because that's her zodiac sign,,lol
