I used the hyperlite on the entire AT.
Not once in 6 months did I ever have a mosquito problem.
And I am not a fan of Deet or anything of the like. Just feels yucky on my skin and god knows what it does to materials. ( I did see some lettering come off a Nalgene bottle when someone who had applied Deet rub up against the bottle.)
there were maybe 2 night where the skeeters were out in droves.
But I easily made my way into my HH, and all was good.
Hope this helps
oh- and for FLORIDA, you might only need a ZRest from Thermarest. I used that after winter in GA. No need for an UQ.
At least, that was my experience. I made sure my tarp was pretty taut and close to me. That adds several degrees.
