Virginia opossums eat varied foods and readily use trash or pet food. Learn about their diet, the limits of tick-control claims, and safer ways to prevent conflicts.
The Florida animal is a Virginia opossum
In Florida, the animal commonly called a possum is the Virginia opossum, Didelphis virginiana. It is the state’s only marsupial: females carry very young offspring in a pouch. Its pointed face, pale-gray coat, small bare ears, and long largely naked tail help distinguish it from a raccoon or a rat.
Opossums are native wildlife. They can climb and may travel along fences or through trees while foraging. Seeing one in a yard does not by itself establish a building infestation or justify removal. Record whether it is simply passing through, feeding at a predictable source, or repeatedly entering shelter.
This guide concerns the Virginia opossum, Didelphis virginiana, identified by FWC as the opossum common throughout Florida. Match the specimen to that species before using its diet account.
The useful takeaways are food, access and the actual encounter. Virginia opossums are omnivores that may use insects, fruit and carrion as well as exposed garbage or pet food. Secure bins, manage compost and remove accessible feed and produce instead of feeding wildlife. A passing visitor differs from repeated occupied shelter use; confirm dependent young before any closure. Keep pets separated, avoid handling wildlife or waste, and have bites or concerning contact assessed by the appropriate health professional.
An adaptable omnivore, not a one-food specialist
Virginia opossums use many available foods. Invertebrates, carrion, fruit, and other plant or animal material can be part of the diet. In urban areas, accessible garbage, pet food, and cultivated fruits and vegetables are especially relevant. There is no universal favorite that explains every visit.
A foraging opossum may clean up material already on the ground, but that does not make feeding wildlife a useful pest-control strategy. Artificial food encourages repeated visits and can attract other animals. Secure the source rather than adding a preferred food in hopes of drawing the animal away.
Garden damage needs observation. An animal can investigate fallen produce without causing every missing leaf or damaged fruit nearby. Look at the specific damage, whether it is fresh, and whether a safely obtained photograph identifies the visitor.
The animal-food group includes insects, snails, earthworms, reptiles, frogs, crayfish, birds and eggs, and small mammals such as mice, rats and voles. UC and Missouri conservation accounts also describe fresh meat and carrion. Fruits, nuts and green plants form another part of this adaptable diet; Missouri lists grapes, persimmons and other fruits particularly in fall and early winter. These are species examples and availability patterns, not a menu that every Florida animal eats in fixed proportions or a reason to feed it.
Carrion feeding is different from killing the animal eaten: Missouri explicitly lists carrion of rabbits, cats, squirrels and mice. Finding an opossum at a carcass therefore does not prove it killed that animal. UC states that opossums do not ordinarily prey on cats or other larger mammals, although a cornered animal or competition for food can lead to an attack. Keep pets separated and secure their food; a small pet should not be used to test the distinction.
Virginia opossums remain active in winter; Missouri’s species account explicitly distinguishes this from winter inactivity of some other visitors. Food searching therefore continues through the year rather than following a fixed hibernation interval. Available foods, weather and the local site affect what is used. This does not establish fixed Florida seasonal diet percentages or a reason to leave food out during colder weather.
Carrion is an animal already dead. At a roadside carcass, keep away from traffic and do not handle or move the remains to lure or diagnose an opossum. Manage food on the property instead of creating another roadside feeding opportunity.
Concrete diet examples make the food groups more useful. Government and university accounts list beetles, crickets and cockroaches among insect foods, alongside slugs and snails. Alabama Extension names apples, persimmons, blackberries, wild grapes and nuts; Pennsylvania’s wildlife account includes mushrooms and acorns, while NPS includes grains and other fungi. These are documented examples rather than a ranking of favorite foods or a promise that an opossum will control each garden pest.
For garden crops, Connecticut wildlife guidance specifically describes visits to vegetables, apples and strawberries, and Alabama Extension names corn while noting that opossums usually are not a significant source of crop damage. Inspect tomato plants, strawberry patches and melon vines for the actual animal and type of loss before attributing it to an opossum. A garden visit or missing produce is not proof of the cause. Published accounts support garden and fruit foraging, but they do not single out tomatoes or melons as preferred targets, and a damaged plant was not necessarily eaten by an opossum.
Do opossums eat thousands of ticks?
The popular claim that an opossum eats thousands of ticks each week is not a dependable foundation for a home tick-control plan. University of Illinois Extension reassessed the claim, contrasting a small captive grooming study with later diet research. In the later work, investigators found ticks on 32 opossum carcasses collected in central Illinois but no tick parts in their gut contents.
That does not prove opossums never eat a tick. It does show why a large fixed tick-consumption number should not be turned into a promise that attracting opossums will reduce Lyme disease risk. Grooming experiments, wild diet, local tick populations, and human disease outcomes are different kinds of evidence.
Use tick identification and appropriate prevention for people and pets. Do not leave food outside to create a wildlife-based substitute for tick inspection, veterinary prevention, or medical advice after a concerning exposure.
Compare other animals using the same resources
Raccoons can also exploit trash and shelter, but their mask, ringed tail, and waste concerns differ from those of opossums.
Skunks and armadillos may dig for soil animals. Armadillos have a mixed diet that includes plants, so calling them exclusively insect eaters is too strong. Neither digging nor a shared food source proves which animal caused lawn damage.
Squirrels entering a house usually direct attention toward climbing routes and upper openings. An opossum is also a climber, but the species, opening, and actual shelter use still need confirmation before exclusion.
Compare all five visitors by resources as well as appearance. Opossums use insects, fruit, carrion and accessible trash, pet food or compost. Raccoons use plant and animal foods, including eggs, crustaceans and small animals, and exploit trash and outdoor feeding. Skunks eat insects and other plant or animal foods and seek shelter and soil-foraging opportunities. Eastern gray squirrels prefer bark, berries, seeds and acorns, with bird seed and access to tree or attic shelter relevant to a visit. Armadillos eat insects, insect larvae such as grubs, earthworms and some plant material; moist soil and garden beds are foraging sites to inspect, not proof that every hole belongs to one. Shared attractants cannot identify the animal or prescribe a common removal method.
Fish or other animal food around a pond is a separate attractant question from fruit, carrion or a trash bin. Opossums are opportunistic feeders; a visitor at an ornamental pond is not proof that it killed a missing fish. Assess accessible food, the actual animal and suitable pond protection.
Raccoons also use aquatic foods.
Keep raccoon contamination in a pool separate from a routine opossum sighting; contaminated water needs an appropriate assessment before use.
A pet door provides possible access rather than identifying the intruder: secure or control its use when wildlife visits, while meeting the pet’s needs, and compare the actual route with other building openings.
Skunks share some resources but not an identical menu: UC describes insects and grubs alongside fruit, bird eggs, garbage and pet food. A yard with exposed poultry eggs, fallen produce or accessible bins can therefore attract more than one omnivore. The animal’s actual appearance and repeated route, rather than the shared food or one digging mark, should determine the response.
Food access and shelter are separate decisions
Use bins with tight-fitting lids and secure them so an animal cannot easily open them. Clean food residue around the storage area. Bring pet food indoors after feeding and store animal feed securely. Pick up fallen fruit and manage compost so it does not provide an open buffet.
Check accessible areas around sheds, decks, and building gaps from a distance. Do not close a suspected den after seeing an adult depart; dependent young may remain. Young first develop in the pouch and later may ride on their mother’s back, so a lone-looking adult is not proof that shelter is empty.
Ask a wildlife professional to determine occupancy and explain repairs once the space is vacant. FWC regulates taking a nuisance opossum under rule 68A-9.010. Traps must be checked at least once every 24 hours. A live-captured opossum must be humanely killed, released on-site, or released within the same county on a property of 40 acres or more with written landowner permission. Contact your FWC regional office for current requirements before any removal. Handling, trapping, transporting, or relocating an opossum yourself is not part of this prevention plan.
Bird feeders and poultry areas deserve separate checks. Clean spilled seed and secure stored feed, then secure chickens and their nests at night: FWC specifically notes that opossums can take sleeping birds or eggs. Remove accessible pet food, fallen produce and food scraps from open compost. A covered trash bin does not solve a second meal under a feeder or in a coop.
As a noncontact deterrent, FWC describes motion-activated water near an opossum entrance while animals are away for the night. Confirm young and occupancy before deciding on exclusion; seeing an adult depart is not a complete vacancy test. UC notes that sprinkler fright responses can fade with habituation. Use the equipment under its instructions as part of food and shelter management, monitor renewed use, and complete screens or mesh repairs only after confirmed vacancy. No permanent natural-deterrent guarantee follows from one quiet night.
Habitat work adds to food control. Cut back overgrown shrubbery, reduce overhanging access where the site allows, stack firewood tightly and store scrap lumber neatly off the ground. UC describes screening vacant under-deck or building openings with hardware cloth and a buried edge where appropriate; fit the repair to the site and confirm occupancy and dependent young first. For gardens, UC describes a poultry-wire barrier with an outward, unsupported top that bends under an animal’s weight. Treat this as a site-specific barrier design, not an opossum-proof promise or a reason to improvise electrical fencing. Identify the animal and choose a lawful, practical design for the property.
Harvest ripe fruit and vegetables promptly while they are still on plants, as well as picking up fallen produce. These are separate ways to reduce easy access to foods in the documented opossum diet; neither promises that every garden visitor will leave. Inspect the actual damage and animal before choosing a garden barrier, and retain suitable plant care rather than using food scraps to divert wildlife.
Chemical repellents and sound devices need separate evidence. UC reports that marketed chemical wildlife repellents do not offer significant results for opossums and warns against using mothballs or household ammonia that way. The UC, FWC and Connecticut opossum guidance does not list ultrasonic devices among effective controls; ask for opossum-specific evidence rather than accepting a general pest-repellent claim. Neither product category replaces managing food access and an occupied shelter route.
Manage food still in an active bird feeder as well as spilled seed. Nebraska’s selective-feeding guide recommends emptying feeders when opossum or skunk conflicts become intolerable; temporarily removing the accessible feeder, including overnight, provides a concrete access-control option. A feeder marketed as squirrel-proof should not be assumed to exclude opossums. Continue cleaning spilled seed and securing stored feed even when the feeder is removed.
WDFW and Connecticut wildlife guidance advise secure garbage storage in a shed or garage where suitable, with bins kept closed until collection. For food residues inside the refuse, rinse empty food containers as local collection rules allow and put meat scraps and other food waste in a closed bag within the secured bin. Double-bagging scraps is not an animal-proof alternative to the bin or closed storage. Keep the storage space closed to wildlife and manage collection timing without providing another outdoor meal.
Keep firewood tightly stacked without den-sized gaps, and use a practical raised storage rack away from the building rather than an untidy pile against a wall. UC’s opossum guidance specifically emphasizes tight firewood stacking and orderly raised storage of other materials. NPS building guidance also recommends raised, separated firewood storage in its rodent-prevention context. These storage practices address inspectable shelter and building access; they do not establish a standalone opossum-removal guarantee or a required distance for every yard.
Lighting is another option to evaluate where opossums return at night. Connecticut’s wildlife agency advises keeping a yard well lit because opossums usually avoid well-lit areas. That guidance does not establish that a brief motion-triggered flash provides the same deterrence, nor that either lighting approach permanently excludes an animal. WDFW adds that floodlights or motion-detector lights placed above a pet door to scare opossums are not long-term solutions. If you try lighting, observe whether visits actually change. Correct accessible food and shelter rather than relying on a light as proof that the animal has left.
Pets, people, and a useful response
Keep pets from approaching or cornering an opossum, and do not handle an animal that appears motionless. Defensive behavior or a quiet posture is not evidence that contact is safe. A feeding visit does not mean the animal is hunting a cat or dog, but close encounters can still cause injury.
Opossums are sometimes described online as immune to rabies. Do not use that claim to decide whether a bite matters. CDC advises urgent medical assessment after a possible rabies exposure, and any bite or scratch should be washed promptly with soap and water. A veterinarian should assess pet contact.
If visits continue after food access is corrected, record where the animal goes and whether it enters a structure. Ask for species identification and a property-specific plan. Prevention may be sufficient for a passing visitor; repeated shelter use, dependent young, or exposure needs a more careful response.
Parasites and waste are separate concerns from the animal’s diet or rabies. UC notes that opossums can carry fleas, ticks, mites and lice, and can host cat and dog fleas. A sighting does not prove infection or establish a Florida disease rate. UC also describes scattered, variable scat near feeding routes; diet means appearance is not a dependable identification rule. If waste accumulates at repeated shelter or feeding sites, keep people and pets away, avoid handling it and request identification and a suitable cleanup assessment. Correct food access without attracting wildlife as a parasite-control strategy.
An opossum seen during the day is not necessarily ill: FWC explicitly says daytime activity can be normal. Keep the timing of a sighting separate from an animal that appears injured or behaves in a concerning way. Observe from a distance, keep pets away and avoid handling or cornering it. For identification and an appropriate response to a concerning animal, contact the nearest FWC regional office for technical assistance; ask which qualified wildlife or rehabilitation resource should assess the situation. Neither daylight activity nor a defensive display supplies a diagnosis.
Frequently Asked Questions
-
Do possums eat cats or small dogs?
Virginia opossums do not ordinarily prey on cats or other larger mammals, according to UC extension. They do eat carrion, and Missouri conservation specifically includes cat carcasses in that diet; feeding on a dead cat is different from killing one. A cornered opossum or competition for food can lead to a defensive encounter and pets can be injured. Do not allow a small dog or cat to approach or corner it, secure pet food and consult a veterinarian after concerning contact.
-
What is a possum's favorite food?
There is no universal favorite. Virginia opossums use varied foods and are often attracted by trash, pet food, and cultivated produce. Remove accessible meals rather than feeding wildlife to test its preferences.
-
Do possums eat garden vegetables and plants?
Yes, cultivated fruits and vegetables can be part of their diet. But garden damage has several possible causes, so use the damage pattern and distant observations to identify the visitor.
-
Are possums dangerous to humans?
A passing opossum is not automatically a danger, but handling or cornering wildlife can cause injury. UC notes possible fleas, ticks, mites and lice; waste at repeated feeding or shelter sites also needs a separate sanitation assessment. A sighting or scat appearance does not prove infection or calculate your risk. Keep people and pets away from the animal and waste rather than handling either. Do not rely on a claim of rabies immunity: wash a bite or scratch and seek prompt medical assessment; consult a veterinarian after pet contact.
-
Will possums eat ticks and reduce Lyme disease risk?
The claim that every opossum eats thousands of ticks weekly is not established by wild-diet evidence. Attracting opossums should not be promoted as Lyme disease prevention. Use tick identification and appropriate prevention for people and pets.
-
How do I keep possums out of my trash cans?
Use tight-fitting secured lids, clean food residue around bins, bring pet food indoors after feeding, and collect fallen fruit. Repeated visits into shelter need a separate occupancy assessment before any closure.
Where suitable, keep the closed bins in a secure garage or shed until collection. Rinse empty food containers as local collection rules allow, and contain meat scraps and other food waste in a closed bag inside the secured bin. A second bag does not replace a tight lid or wildlife-resistant storage.
