Also a Florida resident and have not experienced this. I can offer no help, but can I assume you have rinsed / flushed / bleached the black tank to get rid of them?
Just curious, do you leave your black tank valve open when hooked up to sewers?
Ive been using bleach when doing dishes and put a little down the bathroom sink and shower to keep them from coming out the drains. But the main source seems to be the black tank. I keep the black tank valve closed. Someone mentioned that the Gnats get in through the roof tank ventilation vent and into the tank where they propagate and swarm. When flushing the toilet they fly out into the house. Its really nasty when they fly up your nose and into your food and drink. Especially knowing from where they originated... I'll try bombing them with flea insecticide after the next dump and see if that helps. Also I may devise some type of screen on septic roof vents, maybe that'll keep them from getting in period.
