ultrasonic noise / high frequency deterrent SE1

does anybody know if what can sometimes be called a `sonic no loitering deterrent' is being used in Borough High Street - possibly near the Blue Eyed Maid Pub and from early August?

hi graham

yes `mosquito' is another name for the ultrasonic device.

I hear an ultra sonic sound in the area and wondered if there is a logical reason / solution

Hi All,

This system is often used by owners / Mgt of vacant or high risk properties as a deterrent for possible vandalism or break-ins. A good system although can by annoying in residential areas.

It would be worth pin pointing the exact building or 'place' where it has been installed and then to take this up with the owner/Mgt Company.

Hope this helps.
