When it comes to safeguarding your property, one of the last things you might consider is defending it against opossums. These nocturnal creatures, known for their cat-sized bodies and distinctive rat-like tails, are a common sight in many neighborhoods. Although they play an important role in controlling pests like ticks and insects, opossums can become a nuisance when they venture onto your property. They may raid trash cans, dig up gardens, or even make themselves at home in your attic or under your deck.
Whether you’re a homeowner concerned about your property or a passionate gardener looking to protect your efforts, this guide will help you understand opossum behavior and equip you with practical strategies to keep them at bay.

Understanding Opossum Behavior
To effectively opossum-proof your property, it’s crucial to understand why they’re drawn to it in the first place. As omnivores, opossums are opportunistic feeders. Their diet includes fruits, vegetables, pet food, garbage, insects, and even smaller animals like rodents. If your property offers easy access to food or shelter, you may inadvertently be inviting them in.
Why Opossums Are Attracted to Your Property:
- Food Availability – Trash cans, pet food left outside, ripe garden produce, or compost piles are irresistible to opossums.
- Shelter – Dark, enclosed spaces like attics, under decks, crawlspaces, or sheds provide the perfect hiding spots.
- Water Sources – Puddles, bird baths, or leaky faucets can become watering holes for thirsty opossums.
Now that you know what might be bringing these nuisance critters to your property, it’s time to address these attractions head-on.
Sealing Entry Points
One of the most effective ways to prevent an opossum invasion is to seal any potential entry points around your home and outbuildings. These resourceful creatures can squeeze through surprisingly small openings, so a thorough property inspection is essential.
Steps to Seal Entry Points:
- Inspect Your Home – Check for cracks, holes, or openings in walls, roofs, and foundations. Pay special attention to areas around vents, chimneys, and crawlspaces.
- Secure Doors and Windows – Repair damaged screens and ensure doors (including garage doors) close tightly without gaps.
- Block Off Crawlspaces – Install lattice or hardware cloth over the openings beneath decks, porches, and sheds to deny access while maintaining ventilation.
- Patch Holes Immediately – Use durable materials like steel mesh, caulking, or plywood to cover openings larger than one inch.
Remember, prevention is always easier than dealing with an infestation later.
Securing Trash and Food Sources
Unsecured trash cans and outdoor food sources are some of the most common reasons opossums frequent residential areas. Properly managing these attractants can significantly reduce encounters.
Tips for Securing Food Sources:
- Use Opossum-Proof Trash Cans – Opt for bins with locking lids. For added security, use bungee cords or weights to keep lids firmly in place.
- Remove Pet Food – Feed outdoor pets during the day and bring food and water bowls inside at night.
- Compost Responsibly – Use a compost bin with a secure lid and avoid adding meat or dairy scraps, which are particularly appealing to opossums.
- Harvest Regularly – Collect ripe fruits and vegetables from your garden promptly to prevent them from becoming a snack.

Garden Protection Strategies
Gardens are a common target for opossums, but with a few precautions, you can safeguard your plants without resorting to drastic measures.
How to Protect Your Garden:
- Install Fencing – Use a mesh fence at least four feet tall, and bury it six inches into the ground to prevent burrowing.
- Use Raised Garden Beds – Elevating your plants can make it harder for opossums to reach them.
- Net Your Plants – Drape lightweight netting over fruit and vegetable plants to deter opossums from nibbling on them.
Using Opossum-Repellents and Deterrents
If opossums are persistent, repellents can be an effective way to discourage them. Here are some options:
- Scent-Based Repellents – Use ammonia-soaked rags or commercial products containing predator urine to create an olfactory barrier. Place these near known opossum hangouts.
- Motion-Activated Sprinklers – These devices spray water when motion is detected, startling and deterring opossums.
- Ultrasonic Devices – Install these to emit high-frequency sounds that are unpleasant for opossums but inaudible to humans.
- Natural Repellents – Sprinkle cayenne pepper, garlic powder, or other strong-smelling substances around vulnerable areas.
Creating an Unwelcoming Environment for Possums
The key to long-term opossum control is making your property as unappealing as possible. Small changes can have a big impact.
Steps to Make Your Property Unappealing:
- Keep the Yard Tidy – Remove woodpiles, brush, and debris where opossums could hide.
- Eliminate Water Sources – Fix leaky faucets, drain standing water, and cover bird baths at night.
- Brighten Up the Space – Use motion-sensitive lights around your yard to deter nocturnal visitors.
- Install Physical Barriers – Place spikes or deterrent strips on fences and rooftops to make climbing difficult.
FAQs About Opossum Removal and Control:
What should I do if I find an opossum on my property?
First, make sure it is an opossum and not another wild animal. If it is an opossum, contact a professional wildlife control service to have it safely removed and relocated. Never attempt to touch, trap, harm, or kill an opossum.
What should I do if an opossum is injured?
If you come across an injured opossum, it is best to contact a local wildlife removal professional or animal control agency for assistance. Attempting to handle and treat the injury yourself may cause further harm to the animal.
Are there any diseases associated with opossums?
Opossums are susceptible to some diseases, such as leptospirosis, tularemia, and toxoplasmosis. It is important to wear gloves and use caution when handling any wild animal, and to consult a veterinarian if you suspect an opossum may be infected.
Can I keep an opossum as a pet?
In most states, it is illegal to keep opossums as pets without proper permits and licenses. Here in Virginia, the law specifically states that “it is unlawful to import, possess or sell any wild animal” without proper authorization. Additionally, wild animals do not make good pets and can become aggressive or exhibit unpredictable behavior when kept in captivity.
How can I prevent opossums from entering my property?
Opossums are attracted to food sources such as garbage, pet food, and bird feeders. To prevent them from entering your property, make sure to secure all potential food sources and seal any openings or holes where they may enter.
Remove any fallen fruits or vegetables from your garden, as these can also attract opossums.
Final Thoughts
Preventing opossums from becoming unwelcome guests on your property is all about understanding their behavior and taking proactive measures to address attractants. By sealing entry points, securing food sources, protecting your garden, and employing repellents, you can create an environment that’s far less inviting to these critters.
Lastly, always remember the importance of humane opossum control. These creatures may be a nuisance, but they’re also a vital part of the ecosystem, helping to control pests and clean up decay.
