My grandparents stayed at the club mac hotels (alcudia) last september, and didnt get bit once.
We all went back there last week, and low and behold..... WE GOT EATEN ALIVE!!!!
They are a seasonal thing, so be sure to take out mozzie repellants, sprays, plug ins etc etc.........
we also noticed while we were ther that people had candles on there tables in a bowl..... Turned out that they are also used to keep the mozzies away when sat outside enjoying the night time entertainment.
Just go well prepared........ Also...... JUNGLE FORMULA is a good repelleant. It comes as a cream, and has a better smell compared to other repellants I have used. Its also a fair price at 5 pounds a bottle.
