Help! I'm being tormented by mosquitoes and can't seem to find an effective repellant. It's very strange as I work in West Africa and, for example, received only one bite in 5 months on my last tour. Here in Bayaguana I am bitten constantly, often as many as 10 hits in an hour if I go out in the evening, despite wearing Off, Cutter, Tesco and Boots own brand and now Villeneuve. They bite me through trousers, long sleeved shirts and also get me on the head and face. It's a torment and I'm finding myself reluctant to open my doors or go out. Any tips and advice would be most welcome.
