Mosquitoes - Headaches in smaller working areas?

Mosquitos just eat me alive. If there’s one within a mile it will
find me and leave everyone else around me alone. It is specifically
Vitamin B-6 that works wonders. I was once planning an month long
camping trip to a mosquito infested area, and I began taking 50 to 75
mg of B-6 about six weeks before my trip. I was extremely skeptical,
but I’d read about it and was willing to try anything. I didn’t have
one mosquito bite while camping. They would hover, then fly away. It
works!
