There's research that says efficacy of B vitamins against mosquito bites is low or none, but then there's many anecdotal stories for some it works like magic, yet not everyone. Is there a specific B vitamin blend, an isolate, or type of vitamin B that works better than others!? Are some of the anecdotal stories that failed using inferior B vitamins and saying it does not work!? I've read a bunch of people using B1 to ward of the pests.
I went out to mow a lawn one morning and the skeeters were all over me - I went back inside instead.
Quickly googling B1 and mosquitos, I found some anedotes of B1 trans-dermal patches that help protect against a plethora of bugs like flies and skeeters for 36 hours supposedly.
