An opossum in your yard is a common occurrence, especially if you live in an area with plenty of food and shelter. These fascinating creatures, often called possums, are generally harmless and play a beneficial role in the ecosystem. They are marsupials, meaning the females carry their young in a pouch, and they are the only marsupial native to North America.
Deciphering Opossum Visits
Seeing an opossum in your yard is usually a sign that your yard is providing something it needs. This could be food, water, or a safe place to rest. Since opossums are nocturnal animals, you’re most likely to spot them after dusk or before dawn as they forage for meals.
What Do Opossums Eat?
Opossums have a diverse opossum diet. They are opportunistic omnivores, meaning they eat a wide variety of things. This includes:
- Insects: Beetles, cockroaches, grasshoppers, crickets, slugs, snails.
- Fruits and Vegetables: Berries, apples, grapes, nuts, seeds, leafy greens.
- Small Animals: Rodents, birds, eggs, amphibians (frogs, toads), reptiles (lizards, snakes), carrion (dead animals).
- Human Food Scraps: Garbage, pet food left outdoors.
This varied diet is a primary reason they are attracted to human habitats. Your trash cans, compost piles, or even a pet’s food bowl left outside can be a buffet for an opossum.
Where Do Opossums Live?
Opossums don’t dig their own burrows. Instead, they seek out existing sheltered spaces. This can include:
- Under decks and porches.
- In hollow logs or stumps.
- In dense brush piles.
- In attics, crawl spaces, or garages if they can find an entry.
- In abandoned animal burrows dug by other creatures.
The presence of opossum nesting materials like leaves, grass, or paper within these shelters is a strong indicator of their temporary or semi-permanent residence.
Opossum Behavior Explained
Opossums are generally shy and solitary nocturnal animals. Their most famous defense mechanism is “playing dead.” When threatened, they can enter a trance-like state, appearing dead. This is an involuntary response to extreme stress. They might also hiss, drool, or emit a foul odor to deter predators.
Opossum Identification
Distinguishing an opossum from other backyard visitors is usually straightforward. Key features include:
- Size: They can range from the size of a house cat to a small dog.
- Appearance: They have a pointed snout, a prehensile tail (used for grasping), and can have a grayish-white or brown coat of fur. They are often described as having a “rat-like” appearance, but larger.
- Ears: Large, rounded, hairless ears.
- Pouch: Females have a pouch on their abdomen for carrying their young.
It’s important to note that “possum” and “opossum” are often used interchangeably, but in North America, the creature is technically an opossum.
Why Are Opossums Drawn to Your Yard?
Several factors can make your yard an attractive spot for an opossum.
Food Sources
As mentioned, their varied opossum diet means they’ll readily forage for anything edible.
- Accessible Garbage: Unsecured trash cans are a prime target.
- Pet Food: Food left outdoors for pets is an easy meal.
- Fallen Fruit: Ripe fruit that has fallen from trees can attract them.
- Bird Feeders: Spilled birdseed can attract insects, which then attract opossums.
- Compost Piles: Many compost piles contain food scraps that are a delicacy for opossums.
Shelter and Safety
Opossums seek safe places to rest during the day and raise their young.
- Unprotected Crawl Spaces: Openings under your house can offer ideal shelter.
- Cluttered Yards: Piles of wood, debris, or dense vegetation provide cover and potential nesting sites.
- Water Sources: Accessible water like puddles, bird baths, or leaky faucets can be an attraction.
Proximity to Natural Habitats
If your yard borders wooded areas, fields, or wetlands, it’s a natural extension of the opossum’s territory. They are adapting to urban and suburban environments because these areas often offer abundant food and shelter.
Potential Problems Associated with Opossums
While opossums are generally beneficial (they eat pests like rodents and insects, and ticks), their presence can sometimes lead to issues.
- Damage to Property: They might dig in gardens, tear into trash bags, or nest in attics or under sheds, causing structural damage.
- Mess and Odor: Their droppings and urine can create unpleasant odors and messes.
- Disease Transmission: While rare, opossums can carry diseases like leptospirosis and rabies, though they are not frequent carriers of rabies. It’s important to avoid direct contact.
What to Do When You Find an Opossum in Your Yard
The best approach depends on whether the opossum is causing a problem and whether you want it gone.
1. Observe and Assess
First, watch the opossum from a distance. Is it just passing through? Is it rummaging through trash? Is it showing signs of illness (lethargy, aggression, unusual behavior)? Most of the time, a brief visit is not a cause for alarm.
2. Secure Food Sources
This is the most crucial step in how to get rid of opossums if you want them to move on. Opossums are primarily attracted by food.
- Secure Trash Cans: Use cans with tight-fitting lids. Store them in a garage or shed if possible.
- Don’t Feed Pets Outdoors: Bring pet food bowls inside after feeding.
- Clean Up Fallen Fruit: Regularly collect any fruit that has fallen from trees.
- Manage Compost: Ensure compost piles are secure and don’t contain meat or dairy products.
- Secure Bird Feeders: Clean up spilled seed, and consider a feeder design that is less accessible to larger animals.
3. Eliminate Shelter
If the opossum is nesting or taking refuge under a deck or in a crawl space, you need to make these areas less appealing.
- Seal Entry Points: Inspect your property for openings into attics, crawl spaces, or under decks. Seal any holes or gaps with sturdy materials like wire mesh or metal flashing. Do this after you are sure the opossum has left the area, as trapping it inside can be problematic.
- Clear Debris: Remove piles of wood, leaves, or junk that could serve as a hiding place or nesting site.
4. Consider Opossum Deterrents
There are various methods to discourage opossums from visiting your yard.
Natural Deterrents
-
Strong Smells: Opossums dislike strong odors. You can try placing:
- Ammonia-soaked rags: Place them near areas where you see the opossum. Be cautious with ammonia around pets and children.
- Predator Urine: Available at garden supply stores, urine from coyotes or foxes can deter opossums.
- Peppermint Oil or Garlic Spray: Spraying these around your garden or entry points may help.
- Capsaicin (Chili Pepper): Sprinkle cayenne pepper or chili powder around plants or entryways.
-
Sound Deterrents: While opossums are nocturnal animals, some people have success with ultrasonic devices. However, their effectiveness can vary.
Physical Deterrents
- Fencing: A sturdy fence, at least 3-4 feet high and preferably with an overhang, can help keep opossums out. Ensure it’s buried a few inches into the ground to prevent burrowing.
- Motion-Activated Sprinklers: A sudden spray of water can startle and deter an opossum without causing harm.
Opossum Deterrents Table
| Deterrent Type | Method | Effectiveness | Notes |
|---|---|---|---|
| Smell-Based | Ammonia-soaked rags, predator urine, peppermint oil, garlic spray | Moderate to High | Reapply regularly. Be mindful of pets and children. |
| Taste-Based | Chili powder, capsaicin around plants | Moderate | Can wash away with rain. May harm pets. |
| Sound-Based | Ultrasonic devices | Variable | Effectiveness is debated. May affect other animals. |
| Physical | Fencing, motion-activated sprinklers | High | Fencing is a long-term solution. Sprinklers are effective for deterrence. |
| Habitat Mod. | Securing trash, removing debris, sealing entry points | Very High | Addresses the root cause of attraction. |
5. When to Consider Opossum Removal
If the opossum is causing significant damage or if you are uncomfortable with its presence, opossum removal might be necessary.
Opossum Traps and Relocation
If you decide to use opossum traps, it’s crucial to do so humanely and legally.
- Live Traps: Use a live trap designed for medium-sized animals. Bait it with something appealing like canned cat food, fruit, or peanut butter.
- Placement: Place the trap in an area where you frequently see the opossum.
- Checking the Trap: Check the trap frequently to ensure the animal isn’t stressed or injured.
- Relocation Laws: Important: Check your local and state regulations regarding trapping and relocating wildlife. Many areas have specific rules about what animals can be trapped, how they must be handled, and where they can be relocated. Relocating an animal can also be stressful for it, and it may not survive in a new environment if it cannot find food and shelter, or if it encounters territorial predators.
If you are unsure or uncomfortable with trapping, contact a wildlife control professional. They have the expertise and equipment to handle opossum removal safely and humanely.
Specific Scenarios: Possum in Garden
Finding a possum in garden settings is common, especially if your garden is rich with vegetables, fruits, or attracts insects.
- Damage: Opossums might nibble on ripe tomatoes, berries, or other produce. They also consume slugs and snails, which can be beneficial.
- Protection: To protect your garden, consider:
- Fencing: A fence around your garden beds can be effective.
- Row Covers: Use netting or floating row covers to protect vulnerable plants.
- Deterrents: Apply taste deterrents like chili pepper spray around plants.
- Companion Planting: Some gardeners believe certain plants can deter pests, though evidence for opossums is limited.
Dealing with Opossum Nesting
If you discover an opossum nesting site, especially under your house or in an outbuilding, it’s important to address it carefully.
- When to Act: The best time to deal with an occupied nest is after the young are mobile and have left with the mother. This usually occurs within a few weeks of birth. If you suspect young are present, wait if possible to avoid separating them from their mother.
- Eviction: Once you believe the opossum has vacated, thoroughly clean the area. Use strong-smelling deterrents or motion-activated lights/sprinklers to make the space uninviting for future visits.
- Seal Entry Points: Crucially, seal up any entry points to prevent them from returning or new animals from moving in.
Frequently Asked Questions (FAQ)
Q1: Are opossums dangerous to humans or pets?
