Last summer I watched a mother possum lead three babies across my backyard at midnight, stopping to sniff at fallen fruit and investigate a compost pile I'd forgotten to cover.
That encounter sparked my curiosity about what these nocturnal visitors actually eat to survive in both wild and urban environments.
Possums eat a highly varied diet including insects, fruits, vegetables, small animals, carrion, and in urban areas, pet food and garbage. As omnivorous opportunistic feeders, Virginia opossums consume approximately 90% of available food sources in their environment.
After years observing wildlife and researching with local rehabilitators, I've learned that possums are nature's ultimate survivors, adapting their diet to whatever food sources are available in each season.
What Do Possums Eat? The Complete List
Possums are true omnivores, meaning they eat both plant and animal matter. Their diet varies by season, habitat, and food availability:
- Insects & Invertebrates: Beetles, grasshoppers, crickets, caterpillars, worms, slugs, snails, spiders
- Small Animals: Mice, rats, voles, shrews, small snakes, frogs, toads
- Birds & Eggs: Ground-nesting bird eggs and occasionally nestlings
- Carrion: Roadkill, dead animals, decaying meat
- Fruits: Berries, apples, grapes, persimmons, cherries, fallen fruit
- Vegetables: Corn, tomatoes, peas, beans, sweet potatoes, carrots
- Grains & Seeds: Bird seed, acorns, grains, nuts
- Fungi: Mushrooms, especially in wet seasons
- Urban Foods: Pet food, garbage, compost, kitchen scraps
Are Possums Omnivores?
Omnivore: An animal that eats both plants and animals as their primary food source. Possums are true omnivores, consuming roughly equal amounts of plant and animal matter throughout the year.
Yes, possums are omnivores through and through. Unlike some animals that lean heavily toward plants or meat, possums genuinely eat whatever provides the most calories in their current environment.
In spring and summer, I've observed them eating more insects and fruits. During fall, they shift toward nuts and grains. Winter forces them to rely more on carrion and whatever human-provided foods they can find.
This dietary flexibility explains why possums thrive everywhere from deep forests to downtown city blocks.
What Possums Eat in the Wild?
In natural habitats away from human influence, possums follow a seasonal rhythm dictated by food availability. Their wild diet differs significantly from their urban menu.
Insects and Invertebrates
Insects make up a significant portion of a wild possum's diet, especially during warmer months. I've watched possums methodically turn over leaf litter, hunting for beetles and their larvae.
Common insect prey includes:
- Beetles: Both adults and larvae, found under logs and rocks
- Grasshoppers & Crickets: Caught in low vegetation during night foraging
- Caterpillars: Picked from leaves and stems
- Earthworms: Dug from moist soil after rain
- Slugs & Snails: Consumed shell and all, especially in damp areas
- Spiders: Found in crevices and under bark
After helping a wildlife rehabilitator care for orphaned possums, I learned that insects provide essential protein for growing joeys and fat reserves that adults need for winter survival.
Small Animals and Vertebrates
Possums are opportunistic hunters, not sophisticated predators. They catch small animals that are slow, injured, or unwary.
Their vertebrate prey includes:
- Rodents: Mice, voles, and occasionally young rats
- Shrews: Small, abundant mammal prey
- Amphibians: Frogs and toads near water sources
- Reptiles: Small snakes, including some venomous species
- Fish: Small fish in shallow water or stranded in pools
- Crayfish: Found in streams and wetlands
One fascinating fact I discovered: possums have some natural immunity to certain snake venoms, allowing them to eat venomous snakes that would kill other predators their size.
Birds and Eggs
Ground-nesting birds face predation from possums, who opportunistically eat eggs and occasionally nestlings. This isn't their primary food source, but eggs provide concentrated nutrition when available.
Vulnerable species include quail, killdeer, and other ground-nesters. Possums typically can't catch healthy adult birds but will consume injured ones or carrion.
Carrion and Scavenging
Possums serve as nature's cleanup crew, consuming dead animals they encounter. This scavenging behavior serves an important ecological function.
- Roadkill: A dangerous but common urban food source
- Dead animals: Any carrion found in territory
- Decaying meat: Often ignored by other predators
I've seen possums feeding on roadkill at night, a risky behavior that accounts for significant possum mortality. However, this scavenging prevents disease spread and returns nutrients to the ecosystem.
Plant Matter in the Wild
Plants constitute roughly half of a wild possum's diet, with preferences shifting through the growing season.
Fruits and Berries:
- Wild berries (blackberries, raspberries, elderberries)
- Tree fruits (persimmons, pawpaws, wild cherries)
- Fallen fruit from orchards
- Grapes and wild vines
Vegetables:
- Wild vegetables and greens
- Root vegetables when accessible
- Sweet potatoes and tubers
Nuts and Seeds:
- Acorns (a major fall food source)
- Other nuts (hickory, pecan when available)
- Grains from wild grasses
- Seeds from various plants
Seasonal Diet Changes
Possums adapt their diet throughout the year based on food availability. After three years of trail camera monitoring, I've documented these seasonal patterns:
| Season | Primary Foods | Secondary Foods |
|---|---|---|
| Spring | Insects, emerging plants, amphibians | Eggs, small rodents |
| Summer | Insects, fruits, berries | Small animals, vegetables |
| Fall | Nuts (acorns), fruits, grains | Insects (declining), carrion |
| Winter | Carrion, stored nuts, human food | Bark, buds, garbage |
Spring brings an insect explosion that possums exploit heavily. Summer offers abundant fruits and berries. Fall is all about calorie-dense nuts for building winter fat reserves. Winter forces adaptation to whatever survives the cold.
Urban vs Rural Diet Differences
Possums living among humans develop distinctly different eating habits compared to their wild counterparts. These urban adaptations create both opportunities and conflicts.
Urban Food Sources
City and suburban possums exploit human-provided foods that are often easier to obtain than wild prey:
- Pet Food: Dog and cat food left outdoors is a prized find
- Garbage: Unsecured trash cans provide buffet-style meals
- Compost: Kitchen scraps and decomposing material
- Bird Seed: Fallen seed from feeders attracts them
- Garden Crops: Tomatoes, corn, melons, and vegetables
- Fruit Trees: Fallen and sometimes windfall fruit
Did You Know? Urban possums often have different gut bacteria than wild possums, adapted to process higher-carbohydrate human foods. Their diet in cities can contain up to 50% human-provided food versus less than 10% in truly wild populations.
This urban diet creates conflicts with homeowners, especially when possums raid gardens, scatter garbage, or eat pet food meant for outdoor cats and dogs.
What Attracts Possums to Your Yard
If you're seeing possums regularly, something in your yard is bringing them in. Common attractants include:
- Pet food left outside - The single biggest attractant
- Unsecured garbage cans - Easy meals
- Compost piles - Decaying vegetable matter
- Fruit trees - Fallen fruit is irresistible
- Vegetable gardens - Tomatoes, corn, melons
- Bird feeders - Fallen seed attracts rodents, which attract possums
- Water sources - Pet bowls, ponds, birdbaths
What Do Baby Possums Eat?
Baby possums, called joeys, have dramatically different dietary needs depending on their age and development stage. As a wildlife rehabilitation volunteer, I've helped feed dozens of orphaned joeys.
In the Pouch (0-8 weeks)
Joeys remain attached to their mother's teat inside the pouch for approximately 8 weeks. During this time, they consume only mother's milk and cannot eat solid food.
Transition Period (8-12 weeks)
As joeys outgrow the pouch, they begin riding on their mother's back and sampling solid foods. This weaning period includes:
- Continued nursing (decreasing frequency)
- Soft fruits and vegetables
- Insects (caught by mother or found independently)
- Small amounts of protein
Independent Foraging (12+ weeks)
By 12-14 weeks, young possums forage independently, eating the same varied diet as adults. They're typically weaned completely by around 14-16 weeks.
Feeding Orphaned Possums
If you find an orphaned possum, contact a licensed wildlife rehabilitator immediately. Improper feeding can cause death quickly.
- Check size: If the possum is under 7 inches long (excluding tail), it needs professional care
- Keep warm: Provide warmth but NO food or water until assessed
- Never give cow's milk: It causes fatal diarrhea in possums
- Contact rehabber: Use specialized formulas only under professional guidance
Warning: Never attempt to raise a baby possum yourself without professional guidance. Their nutritional needs are highly specific, and well-meaning but improper feeding kills more orphaned wildlife than starvation.
Foods Toxic to Possums
While possums have adaptable digestive systems, some foods are harmful or deadly. This is especially important if you're caring for injured or orphaned possums.
| Food | Why It's Harmful |
|---|---|
| Cow's Milk | Causes severe diarrhea, dehydration, death |
| Chocolate | Theobromine toxicity, affects heart |
| Processed Human Foods | High salt, sugar, preservatives |
| Bread/Baked Goods | Poor nutrition, potential impaction |
| Junk Food | No nutritional value, health problems |
| Citrus (excess) | Can cause digestive upset in large amounts |
| Onions/Garlic | Can cause anemia with regular consumption |
Adult wild possums typically avoid toxic foods naturally, but urban possums exposed to human garbage may consume harmful items unintentionally.
Why Possums Are Ecologically Beneficial?
Despite their reputation as pests, possums provide valuable ecosystem services. After years of studying local wildlife populations, I've come to appreciate their role.
Natural Tick Control
Possums are tick-eating machines. A single possum can consume thousands of ticks per season while grooming, significantly reducing tick populations in their territory.
Research indicates possums eliminate up to 96% of ticks that attempt to feed on them, making them powerful allies in the fight against Lyme disease and other tick-borne illnesses.
Pest Management
By consuming rodents, insects, and snails, possums help control pest populations naturally. They're particularly effective against:
- Garden pests (slugs, snails, beetles)
- Rodents (mice, voles, young rats)
- Insects that damage crops and gardens
Scavenging Services
Possums clean up carrion that could otherwise spread disease. By consuming dead animals, they:
- Prevent the spread of pathogens from decomposing carcasses
- Recycle nutrients back into the ecosystem
- Reduce fly and insect pest populations that would otherwise feed on carrion
Seed Dispersal
When possums eat fruits, they disperse seeds through their droppings. This helps maintain plant diversity and supports forest regeneration.
"Possums are one of the most benign wildlife species you'll encounter. They don't dig, they don't destroy property, and they actually help control pests that do real damage to your garden."

Common Myths About Possums
Misconceptions about possums abound. Let me address the most common ones I've heard from homeowners:
Myth: "Possums attack cats and dogs."
Reality: Possums are peaceful animals that avoid confrontation. When threatened, they typically freeze, hiss, or play dead. They're not predators of pets.
Myth: "Possums carry rabies."
Reality: Possums are remarkably resistant to rabies due to their lower body temperature. Rabies cases in possums are extremely rare compared to raccoons, skunks, and other wildlife.
Myth: "Possums are dirty."
Reality: Possums are fastidious groomers, similar to cats. They spend considerable time cleaning their fur, which also helps remove ticks.
Frequently Asked Questions
Do possums eat ticks?
Yes, possums eat thousands of ticks per season while grooming. Research shows they eliminate up to 96% of ticks that attempt to feed on them, making them valuable allies in controlling tick populations and reducing Lyme disease risk.
Can possums eat cat food?
Possums can and will eat cat food when available, but it's not ideal for their long-term health. Dry cat food lacks the complete nutrition possums need from a varied natural diet. If you must feed rescued possums temporarily, consult a wildlife rehabilitator for appropriate alternatives.
Do possums eat snakes?
Yes, possums eat snakes including venomous species. They possess a natural immunity to some snake venoms, particularly from pit vipers like rattlesnakes and copperheads. They typically hunt small snakes but will consume larger ones as carrion.
Do possums eat rats?
Possums occasionally eat small rodents including rats, mice, and voles. They're not specialized rat hunters like some predators, but they will catch and consume young or unwary rodents opportunistically as part of their varied diet.
Do possums eat bird eggs?
Yes, possums eat bird eggs when they can access ground nests. This isn't their primary food source but eggs provide concentrated nutrition. Ground-nesting birds like quail and killdeer are most vulnerable to possum predation.
What do possums drink?
Possums primarily drink water from natural sources like puddles, streams, and ponds. In urban areas, they drink from pet bowls, birdbaths, and other standing water. They also obtain significant moisture from the foods they eat, especially fruits and vegetables.
Final Thoughts
Possums are remarkable survivors with an adaptable diet that has allowed them to thrive across North America for millions of years. Understanding what possums eat helps us appreciate their role in ecosystems and coexist with these often-misunderstood neighbors.
Whether you're a homeowner dealing with garden visitors, a wildlife enthusiast, or simply curious about the animal rustling through your trash at night, remember: possums are just trying to survive, much like the rest of us.
The next time you spot one, consider the ecological services they provide. A single possum eating thousands of ticks might just be the best pest control you never hired.
