About the Mosquito Alarm

Using high-frequency sound, the Mosquito alarm helps to reduce anti-social behaviour such as loitering, vandalism, graffiti and violence sometimes caused by youths under 25.

The deployment of Mosquito devices gives communities respite in cases of acute anti-social behaviour and youth nuisance. The devices are successfully being used in areas where there are large groups of young people making life a problem for residents and businesses. It is a reliable and tested product aimed at controlling problem areas and stopping anti-social behaviour escalating or getting out of control.

The Mosquito alarm works not by being loud and painful, but by being annoying to the point where youngsters disperse from any area being controlled by the Mosquito high-frequency sound. The device is usually effective within 20 minutes.

The MK4 Mosquito is equip with a multi-age function allowing the device to be set to 17 KHz to disperse groups of troublesome teenagers. The lower 8 KHz frequency setting should only be used if there are persistent problems with older groups of people but the device should not be used at the ‘all-age’ setting in residential areas.
