In Florida, so far, only bugs which have bitten me are fire ants. They are all over my yard, and when I moved here, I was not aware of them. Now I wont work in yard without long boots and gloves. Their bites are itchy for couple of days, then day 3 through 7, blisters form and itch even more.
I pop them as soon as I see them and apply hydrogen peroxide 3 or 4 times every day and then they heal in a couple of days. Antibiotic ointment does not work. peroxide works great.
I lived in Miami for 10 yrs and had to learn how to deal with fire aunts. Best remedy I found was finding their nests and poured 3 or 4 gallons of scalding boiling hot water right on top of the nest. It proved a determent.
