Ummm, it seems that a small amount of discomfort, fear, and/or pain, all of which is easily escaped by the animal is exactly the point! It is called operant conditioning by negative reinforcement related to a specific behavior.
What it the alternative, hooking up the device to a water cannot, paintball gun or real gun; are those really better?
Do these ultrasound devices actually work? I always thought that was mostly snake oil, or that animals rapidly become desensitized?
Cats keep pissing in/near my bike shed, i have a wifi camera successfully wired up to a YOLOv8 object detector (to detect cats) but never figured out how to actually repel them. I wanted to go with an actuated water spray but it seemed ridiculously over engineered. If i can just blast them with ultrasound that's a lot easier to do...
Not the London Fox. It’s a lot more diurnal now. They know which day of the week the garbage bins are put out and will often walk about quite brazenly in day time to scavenge.
There’s usually a fox sunbathing on my shed roof during the summer, if one of the neighbours cats isn’t around to claim that space.
I’m guessing Surrey foxes are similar.
But, yes, it’s also about their faeces. UK foxes love to defecate on small items rather than boring grass or flower beds. Leave a ball out in the garden and there’s a good chance it will have a fox turd on it the next morning.
