Is Vitamin B12 an effective mosquito repellent?
This Denver Post article suggests that mosquitoes dislike biting people who have excess vitamin B1.
The notion behind the Don't Bite Me! patch is that mosquitoes don't eat vitamin B-1. So slap one of these clear transdermal skin patches on a hairless spot two hours before going out to play with the bloodsuckers, and the excess of B-1 it builds up in your body supposedly will keep them at bay.
Is it true?
