Forget Zanza Click, I tried it and it is completelty useless. I believe that it is supposed to work by stunning your nerve endings by giving them a small electric shock - similar to slapping a bite rather than scrathing it. Unfortunateltly, the affected area (if you are badly affected like me) can spread over up to a couple of inches, and the effect (even with the recommended 10 zaps) is far too localised. I tried it on one of two similar bites, and couldn't tell the difference.
You are better off throwing the device at a mossie, if you see one.
What did work was leaving the fan on at night, and I even followed Mr Wooler's less than obvious suggestion of abandoning the mossie net this time in order to let the fan do its work, and ended less bitten than usual - Cheers Steve.
The best advice I can give, is that when you are not in your room with all of the fans & bug mat etc for protection,
that is when you are most vulnerable, so use an effective reppelant, whatever works best for you. I used 'Neet Deet' (from the Chemist in the UK) on clothes around ankles or on wrist bands, and/or 50% Deet (Jungle Formula) on my ankles and arms, which seemed quite effective. You can even get Jungle Formula wipes wrapped in foil now, which are handy to keep in your beach bag. And don't ever think about leaving it until you get home, as that is when you become the juciest morsel around.
