I have a natural moisturiser that repels mozzies, DS hasn't had a single bite with it on. Which is saying something, we attract them like iron filings to a magnet. Not sure if it's good enough for use in Malaysia, never been there, but the vendor says she use tod live in Cairns and it's all they used.

It's called "bush essentials natural moisturiser". Let me knew if you're interested and I'll send you their email address.
Very interested indeed and the email address would be very much appreciated. Thanks and thank you every one for the prompt response.
