The owner of one of the townhouses on Benjamin Hill Ln. recently put up an ultrasonic animal repellant thing in his front yard. The problem is that this device makes a piercing high-pitched noise that is very audible to my ears. I am sure that other neighbors will probably complain soon, but what can be done to stop this? The device goes off with any motion in the vicinity of his sidewalk, and is an incredible nuisance for neighbors and dog-owners alike.
