What opossums look like and where they live
Virginia opossums have pointed snouts, grayish white fur, and naked ears and tails. Adults weigh 4–14 pounds and show a distinctive footprint pattern with five digits on front and hind feet. They occupy a wide niche, thriving in woodlands, wetlands, and dense urban mosaics that include Brooklyn backyards, rail yards, and park edges. They rely on cavities and cover, so hollow trees, brush piles, and under decks can serve as den sites.
Typical behavior and daily patterns
Opossums are primarily nocturnal and slow-moving, balancing energy conservation with opportunistic foraging. They are omnivorous generalists, eating insects, worms, small vertebrates, fruits, and human refuse when accessible. When threatened, they may freeze, growl, salivate, or perform thanatosis (playing dead), a highly effective defense. They are solitary except for mothers with young, and while they can climb and swim well, they generally avoid prolonged conflict.
Brooklyn encounters: when and where you might see one
Residents most often notice opossums at night near unsecured bins, compost piles, or under stoops. Sightings increase in spring and summer when juveniles disperse and adults forage more to support young. They travel overlapping home ranges, so multiple sightings in a block can reflect a single individual moving through greenways, tree belts, and fence lines.
Common scenarios in urban Brooklyn
- Late-evening rustling under decks or sheds during warm months.
- Scavenged fallen fruit or torn-open trash bags along sidewalks.
- Roadkill along local streets after strikes by vehicles at night.
Health considerations and disease risks
Opossums carry a low risk of rabies among wild mammals and are unlikely to bite when foraging calmly. Their reduced body temperature can inhibit rabies virus replication, which is a noted biological trait. They can host parasites and bacterial pathogens, so handling live or dead animals is discouraged. Secure garbage, remove food scraps, and avoid feeding wildlife to reduce close encounters.

How to reduce opossum visits around your property
Effective management focuses on removing attractants and limiting access to sheltered spaces. Consistent sanitation and exclusion are more reliable than repellents or lethal measures. Coordinate with neighbors when possible, since opossums move across property lines.
Practical prevention steps
- Secure trash in tight-lid containers and place bins away from stoop entrances.
- Pick up fallen fruit and remove accessible compost or secure it in bins.
- Close gaps under porches, sheds, and decks with sturdy mesh, bury edge a few inches outward to prevent digging.
- Remove woodpiles and dense ground cover near walkways that can offer shelter.
- Use motion-sensor lighting or noise devices if activity is concentrated near entry points.
Safe response when you encounter an opossum
If an opossum is on your property, give it space to move out on its own; most will leave at night. If a denning female is under a deck, place a bright light and radio near the entrance by day, then block the opening at dusk after you confirm it has left. Never corner or handle an opossum, and keep pets indoors or leashed to avoid conflicts. If an opossum is behaving erratically, disoriented, or unable to leave, contact local animal control or a permitted wildlife professional for assessment.
Coexisting with opossums in an urban park setting
In Brooklyn parks and greenways, opossums contribute to ecosystem function by consuming ticks, carrion, and discarded human food. Public messaging that stresses non-lethal prevention, secure waste, and respectful viewing distances supports balanced stewardship. Municipal practices that limit accessible food and maintain habitat edges can reduce nuisance complaints while preserving wildlife presence.
When to seek professional help
Contact a licensed wildlife rehabilitator or nuisance wildlife professional if an opossum is injured, orphaned, or repeatedly denning in an inaccessible or high-traffic area. Professionals can humanely exclude animals and advise on long-term habitat modifications. Avoid unlicensed operators and verify credentials before hiring for wildlife work.
