Cell Phones Scare Bugs
South Korea's largest mobile phone operator said Thursday that it will offer cell phone users a new noise service that it says will repel mosquitoes.
SK Telecom Co. said subscribers can pay 3,000 won (US$2.50) to download a sound wave that is inaudible to human ears but annoys mosquitoes within a range of three feet. Customers can then play the sound by hitting a few buttons on their mobile phones.
The company claimed that the service worked during tests.
The service, which begins Monday, has one drawback: it consumes as much battery power as normal cell phone rings.
