I don't know what has happened this year to make them like my blood, even in the UK the little blitters have taken taken a shine to me, I love Marmite, my doctor has blasted me with B12 ( not for mossies). I tried the creams lotions and potions all mentioned, except for the Rum. However, the mouth breath freshener that I reached for in desperation is still the only thing that has worked so far.
At least if they bite someone else their breath will be fresh ;-)
