A Low-Tech Mosquito Deterrent (NY Times)
Outsmarting bugs with a fan may be a poorly known strategy. But the method, it turns out, is endorsed by the American Mosquito Control Association, a nonprofit group based in Mount Laurel, N.J., that publishes a journal bearing its name.
“Mosquitoes are relatively weak fliers,” it says on its Web site, “so placing a large fan on your deck can provide a low-tech solution.” The group says mosquitoes fly slowly — from roughly 1 to 1.5 miles per hour, depending on the species.
Scientists have identified another factor. The breeze from a fan disperses the human emanations (Carbon Dioxide) that allow female mosquitoes to zero in on us.
