Oh my god - bugproof perfumes. [smiley=grin.gif]
I'm sorry, it's just that I'm in the middle of mosquito season and they're so fierce, they could carry you away with nary a change to their pitch. Propane mosquito vacs, Pic coils and Buhach work around the clock.
Really, like Perfume Hound said, there is no such critter. When I bring people from town out to my place and they step out of the plane, if they're wearing fragrance, the rest of us that aren't don't have to worry about bugs, because they're all on the perfumed one, who is doing the bug dance, which is sort of like a combination of these two fellas without the smiles.
BUT.... there are options.
Skin So Soft, the Avon product that has such a cult following as a pleasant bug repellant works only in minor bug invasions, and then only for a short while. And it costs too much for what little it does. But it does sorta work, kinda.
You may laugh, but have you smelled some of the newest OFF mosquito repellant fragrances? They're rather amazing. Their 'Tropical' fragrance smells like some Escada or other, and 'Fresh Scent' is sort of citrusy/refreshing. They aren't incredibly long-lasting (15% Deet), but about the best I've ever smelled.
I'm also sort of test-driving "Spezie" by Lorenzo Villoresi, a fresh-spice unisex fragrance. It seems to attract mosquitoes less than the usual fragrance, but I haven't confirmed that one yet, so don't buy a bottle based on that comment...
Low-sillage is important, of course, which means skin fragrances probably work best of standard fragrances.
