I cant believe this is true....

Mosquito

The Mosquito emits a high-pitched noise that can only be heard by young people and has a record of driving gangs away from trouble spots.

What a bleeding brilliant idea.....I want to know how it works.
Is it good or bad ?
Is it left on constantly or sprayed around when needed ?
