Many stores sell animal repellent for gardens. They include garden centers, pet stores and others. Granules, gel or sprays may be bought to be applied to the areas of the garden to be protected. Ultrasonic devices or spikes may be strategically placed within the garden to deter unwanted visitors.

Scent off gels should not be applied directly to favorite plants and flowers. They affect the animal's sense of taste and smell and this discourages them from fouling flower gardens and beds, driveways and paths. A single application should be effective up to approximately four weeks.

Dogs, cats, rats, rabbits, mice and bats hear at a different range of sound than each other. This means that when ultrasonic devices are set to deter the animals they can be set to emit the appropriate level of sound depending on which animal is to be deterred. This may be effective and the sounds cannot be heard by human beings.

Some ultrasonic devices have been made with twin speakers so that the sound can reach a wider area of the garden. The ultrasonic devices are built with a motion sensor to detect the movement of animals within the garden. These devices are designed for the prevention of cats, dogs and foxes from entering the garden.
