PISCIATA DI GATTO

Try some of these popular home-made dog and cat deterrents:

Pepper: You can make a simple animal repellent with black pepper and chilli pepper. It’s best to grind your own because the smell will be much stronger. Spread the powder on annuals and perennials to keep pets away.
Mothballs: These contain naphthalene which will repel animals. They can be used as a barrier around flowerbeds, but take care with children about.
Citrus: Cats don’t like citrus smells. Scatter some orange or lemon peels to create no-go zones. Citronella oil is considered to be a good cat repellent but generally it does not appear to have an effect on dogs.
Ammonia: Dogs and cats absolutely detest the smell of ammonia. Buy some cloudy ammonia and dilute with 10 parts water. Spray around the garden and yard but always do a small test before applying to plants.
