Foxes have a very strong sense of smell and will eat almost anything. Gardens with chickens or rabbits, or bird feeders, accessible pots, and crops are particularly attractive. You can use some scents to deter foxes, they are said to dislike the smell of chilies and garlic, so pour boiling water and spray your garden as a fox repellant. Other animal repellents are available, but be aware of the risk to other wildlife and always read the manufacturers' instructions carefully. If a territory is marked by a fox, it will take some effort to move them, and if they feel their territory is being threatened, they may increase the amount of marking.
