Mosquitoes sense your fear. :) Well, sort of. Mosquitoes sense the CO2 from your breath (in addition to skin odors) so if you get anxious and breath faster, you could be attracting more of them. :E
I've been around them since the day I was born because we camped every summer at my parents cabin where there was plenty of them. I've gotten used to just ignoring them and they don't seem to bother me.
Thermacell works pretty good if you want to sit outside. Inside, a fly swatter works okay except I have high freq. hearing loss and can't hear them anymore. DW points them out and it's my job to whack them. She has some kinda Avon product she uses.
Worst CG we've been to was next to the Pend Oreille river in Newport WA. Wall to wall mosquitoes and other flying insects so bad it was impossible to be outside. Like a London pea soup fog. Don't go there!!!
