I think the worst thing is yellow flies. I remember one bit me on the leg when I was sitting on the porch at my Aunt’s house.
It really hurt and just kept on hurting in addition to itching. Actually now that I think about it, I have not seen a single mosquito this year.
Aggressive suckers too. They don't let up until they get a bite outta you or you kill them. And that itching, burning welt they leave sticks around as a reminder for a few days.
Gotta love Florida.
