The best thing I've found was the old WW II. "jungle juice"
which was 100% DEET. Hard to find now even in army surplus
places. Now I use something called "Arthropod Repellent"
that works pretty good and has no discernable smell.
Tried the skinsosoft fishing out of Venice La. and it sort of worked but not as good as the AR.
It sure was funny, during the day not a mosquito to be found
after dark they would eat you alive!
We always tried to come back early so we could clean our fish in daylight!
Sure got hammered by Katrina, it was a fisherman's paradise
We always stayed on the floating bunk houses, it was then
$45 a day and that included breakfast and dinner, with the boat tied up along side!
Huge Reds,Kings, Tuna, Cobia even marlin within ten miles of shore.
Hope to go back someday.
I probably need some jungle juice.
I'm telling you those skeeters love me, as well as ticks, fleas, and every other bug out there.
I have some personal opinions about how to deter them, and all I can say is now I COVER the eatable parts of me.
It can get some uncomfortable when you are fishing in the full sun, under certain circumstances.
Okay, show me a bug repellant that actually works and I'll help you market it.
