Aromatic Oils
This is a really good option since it makes use of essential oils like lemon grass oil, orange oil, rosemary oil, lavender oil, lemon oil, eucalyptus oil, and citronella oil. Not only are cats allergic to these smells, but the oils help create a pleasant aroma in your house and your garden, making them the most recommended cat repellents for gardens. It is always better to use a blend of different oils rather than just using one.
