Last year when we stayed at POFQ we saw dozens upon dozens of them but we did not get bitten once and I believe the reason for that was Avon's skin so soft, it is a well known mozzie deterrent in the US, the mozzies hate the stuff apparently!
In the US they do a proper anti mozzie skin so soft but all of the produts work just as well I think. I got the dry oil spray and the bath products, it does really smell lovely... The only downside was DH complaining that he smelt "girly" and try to mask it with using some Lynx, but not a bite in sight!
I have ordered mine off the Avon UK website.
