I'm also a mozzie magnet and have been bitten so badly in the past that I've needed antibiotics, etc (in fact, I've still some of the scars to show!) Anyway, I took the Avon SSS Dry Oil Spray with me in June - stupidly, I didn't put any on before I arrived, and got two bites on my right hand - must have happened either at
Dalaman airport or on the way to the resort.
Anyway, had to go to the chemist to get stuff for them, as my hand swelled up like a paw! However, I religiously plastered myself with the SSS for the rest of my holiday and didn't get a single other bite - although hubby and son did pick up a few.
I will not be going anywhere again without the SSS - seemed to work for me, that's all I can say. I have been told, though, that it's got to be the dry oil spray in the soft and fresh version - the bubble baths, etc, apparently don't work as well.
