Mosquitoes must be a real problem in South Korea because SK Telecom has launched a phone service that claims to repel them, according to the BBC (via Dvice). This $3 per download sound file is being offered to SK Telecom subscribers in order to combat blood-sucking mosquitoes within three feet.

The high-pitched sound is similar to the buzz of a male mosquito, which female mosquitoes tend to avoid during their egg-laying period. The BBC report says the sound uses the handset's battery power faster, but it's expected to be very popular during Korea's hot and humid summers.

Like the popular mosquito ringtone, the mosquito sound cannot be heard by human ears, not even by young people, so the only evidence that the sound is working at all will be the absence of bug bites on your body at the end of the day.
