Next door’s dog is terrified of the urban foxes which roam our area unchecked and seem not to be afraid of anything.
We have an alley up the side of our house which the foxes used to access the road and the smell of them was overpowering and coming into the house through vents. Eventually I went into battle and scrubbed the alley, added chicken wire to the wrought metal gate and half way down the alley created a further barrier of wire fencing with 50mm holes which they find impossible to climb. Then I made another barrier at the garden end of the alley. It sounds extreme but after 10 years of the stink coming through into our toilet, shower and kitchen, all is now sweet smelling,
I grow my own vegetables so I made raised beds with bars across to keep the foxes from messing among the veg. My next anti-fox project is to fix 18” high sections of the wire fencing to the top of each fence panel. Foxes can scale a 6 ft fence but not with the wire at the top.
I have tried all the tricks to keep them away - had no idea that Jeyes was a bad idea - but chilli powder, coffee, male pee, anti cat powder etc, etc, are only effective until the next rain shower. It seems only barriers work.
