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.
