Maybe this only works for some people and many will be sure to call it a Myth.....
But, my first time in Jamaica I was bitten from head to toe.
Since then, we started taking 100mg of Vitamin B1 daily 6-8 weeks before our vacation (and continue taking during). We have not had one bite since! And yes, we do walk on the beach at night and dine with our feet in the sand.
