We’ve had new neighbours in next door and they’ve put two of those ultrasonic cat scarers out - one out the back and one in their front garden.
The problem is that I can hear them and they give me splitting headache. They’re on 24/7 and mean I can’t spend any time in my garden or even open my windows without ending up with a headache.
I’ve tried knocking a couple of times and have now left them a note explaining the situation and asking them to please turn them off but if they don’t is there anything I can do. Would the council consider it antisocial/ a nuisance noise if I make a noise complaint?
