The ‘Mosquito device’ is an electronic device capable of emitting a high frequency sound which is generally only audible to young people aged 25 years old and below.

These devices are installed in various public and private locations (such as in transport stations, and outside shops and houses) with the aim to deter young people from loitering and/or becoming involved in anti-social behaviour.

There is a lack of robust data available on their prevalence in Scotland and the rest of the UK, but anecdotal evidence suggests that these devices are quite commonplace.

Various concerns have been expressed about these devices. These relate broadly to the negative health effects these devices are associated with, and their discriminatory nature.

These devices have been the subject of recent and increased political and media attention, and various organisations such as Children in Scotland and the Scottish Youth Parliament have criticised their use.

While there are a range of complex legal and constitutional considerations associated with both the restriction and ban of these devices, the Scottish government continues to not support their use.

The Scottish government is committed to helping to develop understanding of the impact of these devices on young people. To contribute to this understanding, the Scottish government commissioned Young Scot and the Scottish Youth Parliament, to conduct a short survey of young people’s experiences and views of these devices.
