Am I going to need to bring insect repellant in September. I have not been to Florida since I was a small child so I have no clue about what the insects are like.
I'd bring it - I've been at various times in the year - and I don't see a particular pattern to the bugs - I only know that sometimes they are bad (and you'll be very glad you have the repellant) and sometimes they're not.
The only bugs I ever remember are the love bugs (2 bugs attached). I don't believe that they bite, they are a lot of them and they are just annoying. No need for bug spray.
One year we stayed on site from August 25 to September 3 and the mosquitoes were biting. Of course I got bit the most because mosquitoes love me!! The were particularly bad the night we went to Hoop-de-doo revue.
