darkaether - you are quite correct. The african bees can sting you only once. The ones that particulars bother me are the white faced hornets. Not only can they sting many times they are much more painful than a normal bee, hornet, or wasp. Isoamyl acetate is some bad smelling stuff. I remember it from chem class. It is used to make fake banana scents among other things.

Snakes on an engine block are quite common. All the guides in africa have experienced it one time or another. Ususally at night when the engine is still warm they crawl in. Then during the morning when it is cold they seek a spot in the sun.

I would prefer wasps as a squatter to a snake.
