I've heard mixed things about that stuff. Anyway, I never put anything on my skin that has "parfum" as an ingredient... 50% DEET for me. The worst mozzie attacks I ever endured were in late September in Kefalonia (Roger may confirm the perils of that region if he's been there in late summer...), but I got a few very nasty bites in Campania (Sorrento/Naples) one early October. Those ones came up in big blisters and I still have a scar on my leg from one of them 10 years later! Only DEET will do me - everything else far too risky!
