The set can cover up to 2600sq feet, so even large properties can be effectively covered. Place each stake in open areas 50ft apart to ensure maximum coverage. Make sure there are no large obstacles in the way such as fence posts or foundations as they will block and reduce the distance the sonic waves can travel.
