your skin
 
is the largest organ of your body
having the most square feet of
surface area  
 
it's the first line of ATTACK
 
having brewers yeast regularly (ICE CREAM SHAKES)
makes you
excrete vitamin B1 ON YOUR SKIN and mosquitos hate it...
the TASTE OF IT TO THEM IS 
TABOO
 
you also need to not be wearing denim blue
colors as that attracts mosquitos.
 
i like the 
cutters skinSensations  [correction]
for when they are thick
THEN there's also a bit of wisdom knowing when to retreat 
 
citronella candles work VERY well for us....  
or you can also set up a square window fan 
 
mosquitos can't fly in that breeze very well
