Police and local authorities and finding the Mosquito an invaluable tool in the battle against anti-social behaviour, and are recommending it to businesses and other organisations throughout the country.
The unit generates an annoying high-frequency sound which is generally only audible to people under the age of 20. Usually people over this age have lost the ability to hear at this frequency.
Mosquito has been used around the country to disperse troublesome youths from wherever groups of teenagers tend to congregate, including shopping areas, train and bus stations, public buildings, fast-food outlets and car parks.
The device has a range of about 20 metres, and takes effect in just a few minutes, but the noise will not travel through windows or walls so legitimate
customers, staff or neighbours will not be affected.
The noise created by the Mosquito is very irritating, but not harmful, and the device is totally legal and passed as safe to use.
Available as a simple-to-fit DIY kit or professionally installed, Mosquito can be fitted with a timer and a motion sensor or other accessories if required.
