Mosquito MK4 (Anti-Loitering device) Customise your own kit
The Mosquito, MK4 otherwise known as an anti loitering sound device, anti teenager alarm, teenager repellent or ultrasonic teenage deterrent. Call it what you will, but it is essentially a low power device that makes a pulsing sound similar to an alarm clock. This sound is just out of the range of an adults hearing, which is why it only bothers people under the age of about 25. The sound is not loud or painful, just highly annoying after a short period of time.
Over the 10 years since The Mosquito was launched, CSS have sold many many thousands of them worldwide and in 2017 it still continues to be the MOST effective and safe way to disperse groups of loitering teens from locations they are not welcome.
This page allows you to customise your own Mosquito kit. Whilst we supply security cages, PIR motion detectors, timers and remote controls, for most applications, activating the Mosquito via the switch on the power socket is sufficient. If you will have to mount the Mosquito below 3m / 9 feet though, we suggest purchasing a security cage. The Mosquito itself is cast zinc and is very durable and impact resistant, as it was designed for use in US prisons. That said, it is worth the extra precaution if being mounted low.
As this is a 'customise your own kit' page, you will need to purchase a power supply also. You can choose between UK 3 pin or EU 2 pin power supplies. If you require a power supply that is different to these two options, you can purchase 24v DC power supplies in your local area. Please ansure the power supplies are rated at greater than 500 mA.
