SK Telecom Introduces Mosquito-Repelling Sound Service in South Korea

SK Telecom offers a mobile service that emits a sound to repel mosquitoes by mimicking male mosquito sounds, which female mosquitoes avoid during pregnancy. The sound uses various frequencies to target different mosquito types and is effective within 1.5 meters. Despite using 30% of the phone's battery, it is safe for humans. The service has been popular, with 300,000 downloads since July, and SK Telecom plans to expand to repel other insects like cockroaches and bees.
