What Smells Will Repel Cats?

If you are thinking about using mothballs to repel cats, it is best to look at an alternative solution. Not only will you be saving countless feline lives, but you will also be protecting other animals and yourself from dangerous fumes.

There are plenty of smells that repel cats which you can use instead: 


Vinegar, as we all know, has a strong acidic smell. Cats find the smell of vinegar quite overpowering, which is why using it as a deterrent can be effective.

You can mix some vinegar in water and spray it in your plants or pots and areas where you find cat poop most often. 

One thing to remember is that you need to be careful about spraying too much vinegar on leaves. Vinegar can cause damage to leaves as it can burn them. Therefore, it is also vital to do a test patch first to see how your plants react. 


When we think about garlic, we imagine a delicious smell and some great food. On the contrary, cats imagine walking as far away from garlic as possible. Garlic is famous for its strong smell, so it is not quite popular in the feline community. 

What is great about garlic is that it is accessible, and you can use it however way you like. You can smash some garlic, releasing its juice and scent, and put it in your garden, in pots and the famous spots.

You can also boil some garlic in water, get the juices flowing, add some other ingredients you think can make the mixture stronger. Next, simply spray the mixture on the leaves and in your garden. It is important to keep up with the application as the scent can wear off. 

Essential Oils 

Essential oils are known for their powerful smells and are widely used. The overpowering scent can irritate cats, discouraging them from entering your garden. The most famous cat repellant essential oils include lavender, eucalyptus, and citronella

You can mix a few drops of essential oils in water to create a mixture and spray it in your garden.

You can also adopt other methods like your very own scent diffuser. You can dip some tea bags in essential oils, place them inside a bottle with holes and let the scent linger. This is a good method to adopt as essential oils can be harmful to cats if they ingest them. 


We relate citrus with the feeling of freshness, but cats do not think so highly of it. Citrus, like vinegar as a strong acidic scent that keeps cats away. This means you can use citrus scents like lemons, limes, oranges, and grapefruits to your advantage. 

You can either squeeze some citrus juice in water and make a spray or use the peels. Usually, we throw the peels out, but you can grind them in a powder or use them as they are, placing them in your soil. 

The citrus smell will keep the cats away, and the peels can decompose and act as a fertilizer for your soil. However, the wind can blow the citrus powder, and you will have to reapply it.

Spices like pepper, chilli flakes, and cinnamon have a strong smell that repels cats. You can sprinkle your choice of spice in your garden, staying wary of the wind. Or you can make a spray too.

The spices trigger the cat’s sinuses and irritate the paws, discouraging it from entering the garden.
