The science says no – but my personal experience (in Australia) says that high dose B1 (WITH a B complex – do NOT take a high dose of B1 alone) for some weeks before travel to a sandfly exposure region is effective. Caveats – DO NOT do a sauna and then go out! However it works, it appears that having the skin not so washed must be useful – this from experience. NO NOT be a heavy consumer of alcohol. Appears that this reduces the effect of B1 and/or attracts biting bugs????

Any over-the-counter Vitamin B tablets will work. Start taking them in February, they’ll take a month to work well. But don’t stop until the end of September, or you’ll be bitten again – like me, lesson learnt!

This DOES work! Before taking it, I was plagued with mosquito bites every summer but now I take one Vit B tablet a day and I get no more than 2 or 3 bites in the WHOLE summer. You must take it at the same time every day and be consistent EVERY day, but it is 100% effective, and I can’t understand why scientists reject this cure.

I’m in USA, it’s amazing how much Internet inquiry results say this is a myth.
But I know what I experienced and I know what I saw.
I went biking cross country years ago.
The formula was this…
Take a certain dose daily of b1…
It had to build up in your system, it took 3 weeks to be effective.
Whoala.. sitting in my camp before sunset, I wore a coat that did not breath.
Mosquito’s lined up on my coat looking at me… And I sat there also looking back at them.. the were numerous..
I had every attraction to them but they did not want to taste… No bites..
Very strange encounter.. I could have made pets of them and named them..
One note though is I noticed the vitamins gave my skin an undesirable odor which was not removed in the shower..
It worked well for that trip, and occasion,but, if I was with a romantic interest I would have suffered the bites,
Because frankly I considered the odor on my skin indeed would repel more than just mosquitoes!

In reply to BMcD. Thanks BMcD for sharing your experience. If our trip were to start on Monday, how many days prior should we start taking B1? We have children so would like to be prepared.
