Mosquito Ultra-Sonic Youth Crowd Dispersal System

 

The Mosquito is a non-invasive device that has been specifically designed to disperse groups of youths and teenagers who may be loitering in areas where they could prove to be a nuisance. It is an effective deterrent that causes no physical pain or damage, even in the event of long term exposure. 

 

Effective for the following areas: 

• Outside shop entrances

• School grounds

• Construction sites

• Car parks

• Railway platforms

• Children’s play areas

• Industrial premises

• Residential areas

The system generates a pulsed, near ultra sonic tone at around 16KHz, close to the limit of the hearing range of people under 25 years of age. The sound, though not painful in any way, becomes highly annoying after 5 or so minutes exposure. The result is that most under 20s leave the immediate area, whilst the majority of those over the age of 30, because of natural age related hearing loss, either just hear, or, as in most cases, are totally unaware of any noise at all.  

The system is designed to be used for up to 20 minutes at a time. The unit incorporates a 20 minute cut-off time to avoid unnecessary annoyance. Mosquito complies with the HSE 2005 guidelines and is already widely used by police and local authorities around the UK.

Everyone is talking about Mosquito !   
 

• I am not a teenager. Will the Mosquito annoy me ?

This is very unlikely and research has shown that the majority of people over the age of 25, have lost the ability to hear at this frequency range. It should be borne in mind however, that the unit usually has the desired effect in moving crowds away within just a few minutes. So even if you are able to hear the noise to some degree, you will not have to put up with it for long.

• Who installs the Mosquito ? 

The unit has been designed to be easily fitted as easy as fitting an exterior spotlight  and is supplied with comprehensive instructions. An approved, trained installer should not take more than 1 hour to complete the installation. 

• How robust is the unit ?

The Mosquito is housed in a custom designed, tough vandal resistant metal casing and is consequently very strong. We recommend the unit is mounted at least 2.5 metres high to reduce the risk of vandalism

• How does Mosquito work ?

Mosquito is essentially a sounder unit that emits a very high (ultra sonic) tone that is completely harmless, even with long term use.
