Opossums in Oklahoma — Identification, Behavior, and Coexistence
Scientific Classification & Opossum Biology
The Virginia opossum is the only marsupial native to North America and is widespread across Oklahoma.
Scientific overview:
- Common Name: Virginia opossum
- Scientific Name: Didelphis virginiana
- Order: Didelphimorphia
- Diet: Omnivorous
- Lifespan: Typically 1–2 years in the wild
- Reproduction: Marsupial (young develop in a pouch)
This guide provides an Oklahoma-focused overview of opossum biology, behavior, seasonal patterns, and interesting traits that explain why these animals are so frequently encountered around homes.
Fun Facts & Interesting Opossum Behaviors
Opossums have several unique traits that set them apart from other Oklahoma wildlife.
- Opossums are immune or highly resistant to many snake venoms.
- They consume large numbers of ticks and insects while foraging.
- “Playing dead” (thanatosis) is an involuntary stress response, not a conscious trick.
- Opossums have 50 teeth, more than any other North American mammal.
- They are excellent climbers and swimmers.
- Their body temperature is lower than many mammals, reducing rabies risk.
- Opossums are solitary and non-territorial.
These traits make opossums more beneficial than many people realize.
Opossum Babies and Breeding in Oklahoma
Opossums have one of the most unique reproductive systems of any mammal found in Oklahoma. As marsupials, their young are born at a very early developmental stage and continue growing in the mother’s pouch.
Breeding Season
In Oklahoma, opossum breeding typically occurs from late winter through summer, with peak activity in early spring. Females may have one to two litters per year, depending on environmental conditions and food availability.
Birth and Development
Opossum babies, known as joeys, are born extremely small—about the size of a honeybee. After birth, they instinctively crawl into the mother’s pouch, where they attach to a nipple and continue developing for several weeks.
- Gestation period: approximately 12–13 days
- Time in pouch: about 2 months
- Typical litter size: 6–13 young (though not all survive)
Once they outgrow the pouch, young opossums often ride on their mother’s back before becoming independent.
When Young Opossums Are Seen
In Oklahoma neighborhoods, young opossums are most commonly seen in late spring and summer. By early fall, most juveniles have dispersed to establish their own territories.
It’s common for homeowners to encounter young opossums during this period, especially near sheds, decks, and wooded edges.
Important Awareness Note
If a young opossum is seen alone:
- It may already be independent
- Not all lone juveniles are orphaned
- Intervention is often unnecessary unless the animal is injured
Opossums naturally experience high juvenile mortality, which is part of their normal life cycle.
Where Opossums Are Found in Oklahoma
Opossums are found statewide and adapt easily to different environments.
Common habitats include:
- Wooded neighborhoods and greenbelts
- Creek beds and drainage corridors
- Urban and suburban backyards
- Sheds, decks, and crawlspaces
- Abandoned burrows or brush piles
They often take advantage of existing shelter rather than building their own dens.
Seasonal Activity Patterns in Oklahoma
Opossums do not hibernate and remain active year-round.
Spring
Breeding season begins, and increased movement is common as females search for food and shelter.
Summer
Young opossums begin leaving the pouch and traveling with the mother. Road sightings increase.
Fall
Opossums forage heavily to build energy reserves before colder weather.
Winter
Activity continues but may slow during extreme cold. Opossums seek sheltered areas near structures.
Why Opossums Are Common Around Homes
Opossums are attracted to easy access, not specific homes.
Common attractants include:
- Pet food left outdoors
- Fallen fruit or compost
- Trash cans and unsecured bins
- Crawlspaces and open sheds
- Wildlife feeding areas
- Insect-rich yards
Even well-maintained properties may see opossum activity if food or shelter is nearby.
Opossums are opportunistic survivors with flexible diets and behaviors that allow them to live close to people without requiring large territories.

Opossums, Fleas, and Insects
Opossums are often associated with insects, particularly fleas and ticks.
- Opossums may carry fleas, especially if denning near structures.
- While grooming, they consume insects and ticks encountered during foraging.
- Flea activity around homes is often linked to wildlife movement, not pets alone.
This connection explains why opossum activity sometimes overlaps with insect issues such as Fleas in Oklahoma.
Risks, Concerns, and Common Misconceptions
Opossums are generally low-risk animals, but concerns can arise.
Common concerns include:
- Denning under decks or sheds
- Flea transfer near structures
- Scavenging behavior
- Road hazards
Common misconceptions:
- Opossums are aggressive (they are typically defensive and shy)
- Opossums frequently carry rabies (rare due to low body temperature)
- Opossums are rodents (they are marsupials)
Most issues stem from proximity, not aggression.
Coexistence and Awareness Strategies
Opossums play an important ecological role and rarely need intervention.
Awareness strategies include:
- Securing trash and pet food
- Closing crawlspace openings
- Removing fallen fruit
- Managing insect populations
- Reducing denning opportunities
In many cases, opossums move on naturally once attractants are removed.
