Possums are nocturnal creatures that can become quite a nuisance around residential areas, especially in gardens, attics, and rooftops. While they are protected in many regions like Australia, homeowners are still in need of humane methods to deter them. One of the most effective and non-lethal options available today is the ultrasonic possum deterrent. Sold at popular home improvement stores like Bunnings, these devices offer a practical and chemical-free solution to possum problems. They operate on the principle of emitting high-frequency sound waves, undetectable to human ears, which irritate and drive away possums without causing them harm.
Understanding Ultrasonic Possum Deterrents
What Are Ultrasonic Possum Deterrents?
Ultrasonic possum deterrents are electronic devices designed to emit high-pitched sounds that are uncomfortable for possums. These sound frequencies typically fall outside the human hearing range but are highly disruptive to many types of animals, including rodents and marsupials like possums. The idea is to create an environment that possums find intolerable, encouraging them to relocate without resorting to traps or poisons.
How Do They Work?
These deterrents usually work through motion sensors or operate on a timed cycle. When a possum enters the detection range, the device activates and releases a burst of ultrasonic sound. In some models, flashing lights may accompany the sound to enhance effectiveness. Because possums rely heavily on their sense of hearing for navigation and communication, these disruptions are often enough to convince them to stay away from protected areas.
Benefits of Using an Ultrasonic Possum Deterrent
Humane and Non-Toxic
One of the greatest advantages of using ultrasonic possum deterrents is their humane approach. Unlike traps or chemical repellents, these devices do not physically harm animals or expose them to dangerous substances. This makes them a suitable option for homeowners concerned with ethical treatment or who want to comply with local wildlife protection laws.
Low Maintenance and Easy Installation
Most ultrasonic deterrents are plug-and-play devices. Some are battery-powered, while others connect to a power outlet or use solar energy. They typically require minimal maintenance just occasional checks to ensure proper function and perhaps a wipe-down to clear dust or debris from sensors.
Eco-Friendly and Chemical-Free
Because they don’t rely on sprays, traps, or poisons, ultrasonic possum deterrents are safe to use around pets, children, and plants. They offer an environmentally friendly alternative to harsher pest control methods that may contaminate soil or groundwater.
Wide Coverage
Depending on the model, ultrasonic devices can cover large areas of outdoor or indoor space. Some even come with adjustable frequency settings to target different kinds of pests beyond just possums, such as rodents, birds, or cats.

Customer Reviews and Effectiveness
Reviews from Bunnings customers indicate a mixed but generally positive experience. While some users report immediate success in deterring possums, others find that it takes time or requires strategic placement for the device to be effective. It’s important to remember that no pest control method is universally perfect, and ultrasonic deterrents work best when combined with other preventative measures such as securing garbage bins and sealing entry points.
Tips for Maximum Effectiveness
Correct Placement
For best results, ultrasonic devices should be installed at a height and angle that aligns with where possums are likely to enter or pass through. Aim the device toward rooftops, trees, garden beds, or fences where activity is most common. Some units allow for adjustable positioning or mounting brackets, which can help direct sound waves more precisely.
Use in Combination with Other Deterrents
Ultrasonic possum deterrents are more effective when used alongside other methods. Consider the following strategies:
- Trimming tree branches that give possums roof access
- Installing possum-proof fencing or netting
- Securing garbage bins and pet food
- Using natural repellents like camphor or garlic sprays
Regular Maintenance
Like any outdoor electronic device, ultrasonic deterrents require periodic checks to ensure they’re clean and functioning. Dust, spider webs, or rain can affect the sensors. For solar-powered models, keep the panels clean and exposed to direct sunlight.
Considerations Before Purchasing
Safety for Pets
While ultrasonic deterrents are safe for humans, they may affect pets, particularly dogs or cats, depending on the frequency used. Always check the manufacturer’s guidelines regarding pet safety before installation. Some models are specially designed to avoid interfering with domestic animals.
Weather Resistance
If the deterrent will be used outdoors, ensure it has weatherproof housing. Rain, wind, and direct sun can damage electronics if they aren’t designed for exterior use. Most models sold at Bunnings are built with this in mind, but it’s worth double-checking before purchase.
Legal and Ethical Compliance
In regions like Australia, possums are protected species. Any attempt to trap, relocate, or harm them without a permit is illegal. Ultrasonic deterrents comply with wildlife protection laws because they do not injure the animals, but it is still good practice to check local regulations or seek advice from wildlife agencies if needed.

Whether you’re dealing with nightly visitors in your roof cavity or garden invaders eating your plants, these devices can provide an effective defense. By understanding how they work, choosing the right model, and placing it correctly, homeowners can enjoy a possum-free environment without resorting to drastic or harmful measures. As with any pest control method, patience and consistency are key. Combining ultrasonic deterrents with good property maintenance practices will yield the best results in keeping possums at bay.
