Do Moth Balls Deter Possums? Exploring the Truth Behind This Repellent Method
Do moth balls deter possums? The answer is a resounding no. While moth balls emit a strong odor, they are not an effective or safe way to deter possums and can pose significant risks to humans, pets, and the environment.
The Allure of Moth Balls: A Misguided Hope
For homeowners battling unwelcome possums, the promise of a simple, readily available solution is understandably attractive. Moth balls, with their pungent smell, seem like a logical deterrent. However, relying on them for possum control is not only ineffective but also potentially dangerous.
Why Moth Balls Fail to Deter Possums
Possums are adaptable creatures, and while they may initially be put off by the strong odor of moth balls, they quickly habituate to it. There are several reasons why moth balls are ineffective as a possum deterrent:
- Habituation: Possums are remarkably resilient and can quickly adjust to the presence of moth balls. The initial aversion soon fades, and the possums will return.
- Odor Dissipation: The effectiveness of moth balls relies on the concentration of their fumes. Outdoors, these fumes quickly dissipate, rendering them useless.
- Lack of Targeted Repellency: Moth balls emit a general odor designed to kill moths. Possums are not susceptible to the chemicals in the same way.
- Alternative Food Sources: Possums are primarily motivated by food. The presence of readily available food sources, such as garbage, pet food, or fruit trees, will outweigh any aversion to the smell of moth balls.
The Dangers of Using Moth Balls
The primary chemicals in moth balls, paradichlorobenzene and naphthalene, are toxic. Their use as a general repellent is illegal in many jurisdictions. The risks associated with moth balls include:
- Human Health Risks: Exposure to moth ball fumes can cause headaches, nausea, dizziness, and respiratory irritation. Prolonged exposure can lead to more serious health problems, including liver and kidney damage.
- Pet Poisoning: Pets are particularly vulnerable to moth ball poisoning. Ingestion can cause vomiting, diarrhea, seizures, and even death.
- Environmental Contamination: Moth balls can contaminate soil and water, harming wildlife and the environment. The chemicals can persist in the environment for extended periods.
Effective and Safe Possum Deterrents
Instead of relying on moth balls, consider these humane and effective methods for deterring possums:
- Remove Food Sources: Secure garbage cans with tight-fitting lids, bring pet food indoors at night, and clean up fallen fruit from trees.
- Eliminate Shelter: Seal off access to under decks, sheds, and other potential nesting sites. Trim overgrown vegetation to reduce hiding places.
- Motion-Activated Lights and Sprinklers: These devices can startle possums and discourage them from entering your property.
- Commercial Repellents: Some commercially available repellents are specifically formulated to deter possums. Choose products that are humane and safe for the environment.
- Professional Wildlife Removal: If you have a persistent possum problem, consider hiring a professional wildlife removal service.
Legal Considerations
It’s crucial to understand that using moth balls as a general pest repellent is illegal in many areas. Always check your local regulations before using any pest control product.

Understanding Possum Behavior
To effectively deter possums, it helps to understand their behavior. Possums are nocturnal animals, meaning they are most active at night. They are opportunistic omnivores, meaning they eat a wide variety of foods. They are also excellent climbers and can easily access elevated areas.
Frequently Asked Questions About Possum Deterrents
Can moth balls kill possums?
While moth balls are unlikely to kill a healthy adult possum outright, they can cause serious health problems if ingested or exposed to high concentrations of fumes. The toxicity can be particularly harmful to young or weakened possums. It’s best to avoid using them entirely.
Are there natural alternatives to moth balls for deterring possums?
Yes, several natural alternatives can be effective. Citrus peels, such as orange or lemon, can deter possums due to their strong scent. Garlic and chili peppers are also known to repel them. Scattering these around your property can create a less inviting environment.
How can I prevent possums from nesting in my attic?
The best way to prevent possums from nesting in your attic is to seal off any potential entry points. This includes repairing holes in the roof, patching gaps around pipes and vents, and installing wire mesh over chimneys. Regularly inspect your attic for signs of possum activity.
What should I do if I find a possum in my yard?
If you encounter a possum in your yard, do not approach it. Possums are generally not aggressive but may bite if they feel threatened. Simply leave it alone and allow it to move on. If you are concerned about its presence, contact a local wildlife control service.
Do ultrasonic pest repellents work on possums?
The effectiveness of ultrasonic pest repellents on possums is debatable. While some studies suggest they may have a limited effect, others show that possums quickly habituate to the sound. It is best to rely on other, more proven methods.
Is it safe to trap and relocate possums?
Trapping and relocating possums can be stressful for the animal and may not be the most effective solution. Relocated possums often struggle to survive in unfamiliar territory. Additionally, relocating wildlife may be illegal in your area. Check with your local authorities before attempting to trap and relocate a possum.
What attracts possums to my property?
Possums are attracted to properties that offer food, water, and shelter. This includes readily available food sources such as garbage, pet food, and fruit trees, as well as potential nesting sites under decks, sheds, and in attics. Removing these attractants is crucial for deterring possums.
How can I protect my fruit trees from possums?
To protect your fruit trees from possums, consider netting the trees with bird netting or hardware cloth. You can also wrap the trunks of the trees with smooth metal flashing to prevent possums from climbing them. Regularly cleaning up fallen fruit will also help to reduce their attraction.
What are the signs of a possum infestation?
Signs of a possum infestation include droppings, tracks, disturbed garbage, and noises in the attic or under the house. You may also notice damage to plants or partially eaten fruit.
Are possums dangerous to humans?
Possums are generally not dangerous to humans, but they can carry diseases such as leptospirosis and tuberculosis. They can also bite if they feel threatened. Avoid direct contact with possums and seek medical attention if you are bitten.
How can I humanely deter possums from my garden?
To humanely deter possums from your garden, try using physical barriers such as fencing or netting. You can also sprinkle cayenne pepper around your plants, which will deter possums without harming them. Ensure there are no easy water sources available.
Is there a specific smell that repels possums?
While there’s no single guaranteed scent, many find success with predator urine (available at some garden stores), or strong scents like peppermint oil diluted in water and sprayed around areas possums frequent. Remember that success can vary.
