What Can I Spray to Keep Possums Away?

Wildlife 2

Possums might be cute to some, but they can also be a nuisance, especially if they’ve taken a liking to your garden or property. From ravaging your flower beds to rummaging through your trash, these nocturnal creatures can cause quite a mess. If you’ve been wondering, “What can I spray to keep possums away?” you’re in the right place.


You can spray natural repellents such as peppermint oil, cayenne pepper, garlic, molasses, or quassia chips to keep possums away. Commercial possum deterrent sprays are also available. Alternatively, you can create homemade possum deterrent sprays using ingredients like hot peppers, garlic, or molasses. Apply the spray during the cooler parts of the day, such as early morning or evening, for maximum effectiveness.

Natural Sprays and Repellents

There are various natural sprays and repellents that you can use to keep possums at bay. These include:

Peppermint Oil

Possums have a strong sense of smell, which you can use to your advantage. They find the scent of peppermint oil particularly offensive, making it an effective repellent.

Cayenne Pepper

The capsaicin in cayenne pepper irritates possums. You can create a spicy spray by mixing cayenne pepper with water and dish soap. Spray this concoction on plants and areas where you don’t want possums.


Garlic is another natural repellent for possums. You can place garlic cloves around your property or create a garlic spray by mixing minced garlic with water.


A solution of molasses dissolved in water can make your garden leaves less appealing to possums. Add a squirt of dish soap to the mix to help it adhere to the leaves.

Quassia Chips

Quassia chips can be used as a deterrent as possums find their smell repugnant. Soak the chips in water and spray the solution around your garden.

Commercial Possum Deterrent Sprays

If you’re looking for a ready-made solution, there are commercial possum deterrent sprays available. These sprays contain ingredients that possums find repugnant, like the ones mentioned above. Some recommended products include Natural Armor Animal & Rodent Repellent Spray and Bonide’s Shot-Gun Repels-All Animal Repellent Spray.

Homemade Possum Deterrent Sprays

If you prefer a DIY approach, you can create your own possum deterrent spray at home. Here are few recipes:

Spicy Mix Spray

Mix hot peppers, hot sauce, or cayenne pepper with water and dish soap. Spray this around your yard to deter possums.

Garlic Spray

Crush garlic cloves and place them around your yard. Alternatively, mix minced garlic with water, add it to a spray bottle, and spray it on surfaces where possums are active.

Molasses Solution

Mix a cup of molasses with 1 litre of water, stir until the molasses dissolves, and pour it into a spray bottle. Spray the solution onto foliage to deter possums from eating your plants.

How to Apply the Spray

To ensure maximum effectiveness, apply the spray during the cooler parts of the day, such as early morning or evening. Follow the label instructions for dilution rates and application methods. Test your sprayer with water before mixing the pesticide to ensure proper coverage. Use spot treatments where the pest is most prevalent, avoiding widespread applications.

Potential Side Effects

While many possum deterrent sprays are designed to be safe for plants, pets, and other animals, there can still be potential side effects or dangers. Some chemical animal repellents can cause pollution and have adverse short-term and long-term effects. Always choose a product specifically designed to be safe for the environment and other living organisms, and follow the application instructions carefully.


Possums can be a nuisance, but there are various sprays available to keep them away. From natural oils to homemade concoctions, there are plenty of options to choose from. Always remember to apply the spray correctly and regularly for the best results.
