I learned about this a couple of years ago visiting a friend of mine who lives in the Tigre Delta. It's sort of like a suburban version of Venice, except with a jungle, and lots and lots of enormous black mosquitoes. After a while sitting in her living room talking to her, I wondered aloud why we weren't getting bitten by mosquitoes, and she pointed out the electric fan overhead and explained it discouraged the mosquitoes. Very useful!
And despite the danger of fan death when it gets hot enough, I think fans are more certain not to have long-term toxic effects than mosquito spirals or DEET.
