Some insist that cockroaches don't bite, that I must be dreaming. Well at 2 am I could feel a rather large creature taking a bite out of my scalp and I whacked it with a slap to my head and turned on the light. There on the sheet was a filthy quivering fat disgusting roach.

Of all the things to worry about while diving in Asia. Bugs! Mosquitoes are another thing that can be most annoying. It is not common, but in some remote areas dengue and malaria are real possibilities.

Mosquitoe nets can help out. The malaria carrying mosquito is reported to be most active at dusk. Some people use insect repellent. There are pills you can take to prevent malarai but I choose not to. I spend quite a bit of time in remote areas and the chemicals are said to build up in your liver over the long term.

For some people there can be halucenagenic reactions to the drugs as well. That might not be a good thing if you already have a tad bit of narcosis going on at depth. Which brings up the topic of DCS which would be an absolute nightmare to have in some of these places.

You would probably have to be flown into Australia from a lot of these places. Maybe several days away. Dive conservatively and make sure your DAN ins is paid up, just in case.
