Mosquito population in China quickly multiplies during autumn and a Chinese Web site trying to cash in on the problem, is offering Chinese consumers a special mobile phone software that claims to repel mosquitoes. The software, available on download over the Internet, claims to release mosquito repellent waves.
Over 1,000 Internet users downloaded the free software and answered the survey online attached to the file. But most of them said the software is not effective in repelling mosquitoes and claimed they have suffered severe headaches the morning after...
Xu Renquan from the Shanghai Municipal Center for Disease Control and Prevention said that they have done similar experiments but the outcome was not successful. He adds that there are different mosquito types in different regions, saying that it would be effective to other region and might not be effective to some.
