Hehe Leftiant :-) 
Some good suggestions here - I'm glad I wrote this post. I've also read eating loads of marmite a day or so before works as well. I'll be trying out that Neem stuff first I reckon, failing that will try the Dettol and Baby oil option. I can't stand the taste of marmite, and as I mentioned, I just don't trust the ingredients of Bushmans. Telfast is something I'll probably seek out as well. Soov does very little in my experience.
