Well, I guess I'm the odd one out here!
We, too, live in Florida (Lakeland). We live between two lakes and mosquitos are plentiful. When I bought this bungalow, the front porch was screened in. The mosquitos were horrible! They would come in little openings or the screen door and never be able to leave, so they just ate us up! We took the screen off and it got so much better! I think the breeze kind of blew them away or something. I'm not sure, but it's much better!
A big fan and anti-mosquito plants really helped, too.
We just bought the house across the street and can't wait to rip off the closed in front porch to have a big open porch again!
