how to keep possums away

Ever found your trash can raided, your garden looking like a salad bar, or heard strange noises coming from your attic at night? You might have a possum problem. While these nocturnal marsupials play an important role in our ecosystem, their foraging habits can often lead to conflicts with humans and damage to our property. Understanding how to deter them safely and humanely is crucial for maintaining a peaceful coexistence.

Dealing with possums isn’t just about protecting your vegetable patch or keeping your trash contained; it’s also about preventing the spread of diseases and ensuring the structural integrity of your home. Possums can carry parasites and diseases harmful to both humans and pets, and their nesting habits can lead to damage to insulation and wiring in attics and crawl spaces. Learning effective possum deterrent methods is a responsible step towards safeguarding your health, property, and the environment.

What are some frequently asked questions about possum removal?

What smells deter possums effectively?

Several strong odors can deter possums, but ammonia and its derivatives are among the most effective. The smell mimics the scent of predator urine, signaling danger to the possum and encouraging them to seek shelter elsewhere. Other reported deterrent scents include garlic, mothballs, and some strong essential oils, although their effectiveness can vary.

Ammonia-based products, such as diluted household ammonia, can be strategically placed in areas where possums frequent. Soak rags in the solution and place them around gardens, under decks, or near entry points to your home. It’s crucial to reapply the ammonia regularly, especially after rain, as the scent will dissipate over time. Note, however, that ammonia can be harmful to plants in high concentrations, so dilution is important. Be mindful of using ammonia products in areas accessible to pets or children. While garlic and mothballs are sometimes mentioned as possum deterrents, their effectiveness is less consistent. Some gardeners report success with scattering crushed garlic cloves around plants, while others find it has little impact. Mothballs contain naphthalene or paradichlorobenzene, which are toxic chemicals, and their use in deterring animals is often discouraged due to environmental and health concerns. Strong essential oils, such as peppermint, eucalyptus, and citronella, may offer some temporary relief, but they need frequent reapplication and may not be potent enough to deter determined possums. A multi-pronged approach, combining scent deterrents with other exclusion methods, is usually the most effective way to manage possums.

Will motion-activated sprinklers keep possums away?

Motion-activated sprinklers can be a moderately effective tool for deterring possums, as the sudden burst of water can startle and discourage them from entering your yard. However, their effectiveness varies depending on the individual possum, the consistency of the sprinkler’s placement and coverage, and the availability of alternative food sources.

While the surprise of a sprinkler blast can certainly scare a possum, keep in mind that these animals are adaptable. A particularly persistent or hungry possum might learn to tolerate the water or find ways to avoid the sprinkler’s range. To maximize the effectiveness of motion-activated sprinklers, position them strategically in areas where possums frequently visit, such as near gardens, garbage cans, or pet food bowls. Ensure the sprinklers have a wide range of motion and are properly calibrated to avoid false alarms from other animals or wind, which could desensitize the possums to their presence. Ultimately, motion-activated sprinklers are best used as part of an integrated pest management strategy. Combining them with other deterrents, such as removing food sources, securing garbage cans, and using physical barriers, will provide a more comprehensive and reliable solution for keeping possums away from your property.

How do I possum-proof my garbage cans?

The most effective way to possum-proof your garbage cans is to secure them with tight-fitting lids and latches or bungee cords, store them in a secure shed or garage, and regularly clean the cans to remove food odors that attract possums.

Possums are attracted to the scent of food, making garbage cans a prime target. Simply having a lid isn’t always enough, as possums are surprisingly adept at opening unsecured bins. Heavy-duty lids that clamp or lock into place are best. Bungee cords can also work well, but ensure they are strong enough to resist a determined possum. If possible, storing your garbage cans inside a shed, garage, or even behind a sturdy fence adds another layer of protection. Make sure the shed or garage door is also secured to prevent the possum from gaining access. Regularly cleaning your garbage cans, inside and out, with soap and water or a disinfectant cleaner will minimize attractive food odors. Pay particular attention to spills and residue buildup. Consider double-bagging particularly smelly garbage, like meat scraps, to further reduce odors. Avoid leaving garbage bags outside the cans, as this provides an easy meal for possums and other scavenging animals. Over time, consistent efforts in these areas will dramatically reduce possum interest in your garbage cans and property.

Can I use netting to protect my garden from possums?

Yes, netting can be an effective way to protect your garden from possums, but it’s crucial to choose the right type and install it correctly to ensure it works. Netting acts as a physical barrier, preventing possums from accessing your plants and vegetables.

While netting offers a direct solution, its effectiveness depends on several factors. The mesh size is crucial; it needs to be small enough to prevent possums from squeezing through. Heavy-duty netting, like bird netting with a small mesh size (less than 2cm), is preferable to flimsy, easily torn materials. Furthermore, proper installation is key. The netting must completely enclose the plants you want to protect, extending to the ground and being securely anchored to prevent possums from lifting or burrowing underneath. Leaving gaps or loose sections will render the netting ineffective, as possums are adept at finding weaknesses. Beyond the type and installation, consider the overall practicality. Netting large areas can be cumbersome and visually unappealing. It also requires regular maintenance to ensure it remains intact and free of holes. For larger gardens, you might consider a combination of netting for vulnerable plants and other deterrent methods like motion-activated sprinklers or ultrasonic devices for the perimeter. Remember to remove the netting when the plants are no longer vulnerable to prevent trapping birds or other wildlife.

Do ultrasonic devices actually repel possums?

The effectiveness of ultrasonic devices in repelling possums is generally considered low and unsupported by scientific evidence. While some anecdotal reports suggest temporary displacement, possums are adaptable creatures and quickly habituate to the high-frequency sounds, rendering the devices ineffective in the long run.

The theory behind ultrasonic repellents is that the high-frequency sounds emitted by the devices are irritating or disruptive to possums, causing them to avoid the area. However, numerous studies and expert opinions indicate that possums, like many other animals, quickly learn that the sounds pose no real threat. Their natural curiosity and drive to find food and shelter override any initial aversion to the ultrasonic noise. Factors such as the device’s frequency, intensity, and the surrounding environment also play a role in its (lack of) effectiveness. A noisy urban environment, for example, can easily mask the sound. Furthermore, relying solely on ultrasonic devices can be detrimental as it creates a false sense of security. While you *think* you are protecting your property, possums may continue to cause damage and establish themselves nearby, simply ignoring the device. It’s much more effective to focus on proven deterrents like eliminating food sources, securing garbage cans, and blocking access points to your house or garden. Combining several strategies will have the best chance of keeping these adaptable marsupials away from your property.
