I have to agree with Gill - as previously posted, I went armed with everything from wristbands with 100% deet, sun creams with anti-mossie/wasp properties, plug in things, after sun with anti-everything, a zapper, bite ease and who knows what else (apart from a very heavy suitcase!) - I didn't see one mossie - tons of wasps (who by the way, obviously couldn't read as they were not deterred!!) but no mossies. Result - no bites! I've been bitten more at home this year! As someone that couldn't walk for 2 days after being bitten I was rather relieved!
I wonder if the mossies were all on holiday in one part of the island this year! We were in Glyfada (to the west).
