the mosquito is a device for those who don't know it emits a 17 khz signal very loudly, this frequency is only audible by persons between the age of 13-25.
it is designed to keep persons with in that age group OUT of certain areas
by causing a painful ringing in their head
the device is mainly used in the UK but is gaining in popularity here
i personally think this thing should be outlawed,
what are your opinions?
