If you’ve ever spotted a slow, scraggly, white-faced mammal nosing around your compost, you might have wondered whether it’s plotting a horror movie or just hunting for snacks.
Good news: most possums (properly called opossums in the Americas) are more awkward than awful, more scavenger than serial menace. Let’s tiptoe into their world with curiosity, some facts, and a sprinkle of gentle caution so you can share your neighborhood without drama.
Meet the possum: oddball neighbor, night-shift cleaner
Possums are marsupials—pouched mammals—so they’re cousins (in spirit) to kangaroos, not raccoons or rodents. They wander at night, nibbling on insects, fruit, eggs, and the occasional leftover pizza crust.
They look scary when they hiss, bare teeth, or play dead—yes, “playing possum” is a real trick—but those are mostly defense moves, not aggression. They prefer avoidance to altercation.
Are possums dangerous to people?
Short answer: not really. Opossums are shy and non-confrontational. They rarely attack humans and will usually flee or freeze if cornered.
That said, any wild animal can bite if it’s scared or sick. It’s wise to avoid grabbing or cornering a possum, and to keep curious kids and pets at a safe distance until the animal moves on.
Threats to pets and property
Possums are opportunistic eaters. They may raid pet food left outdoors or tip over a trash can, which can be annoying. They’re less likely to confront a healthy dog or cat than a raccoon would.

Disease risk: rabies and other worries
One common fear is rabies. Fortunately, opossums have a lower body temperature than many mammals, which makes them much less likely to contract rabies.
They can, however, carry fleas, ticks, and intestinal parasites. If you or your pet are bitten or scratched, wash the wound and call a doctor or vet. For a broader look at wildlife and shared diseases, check out this post about raccoons: 10 Amazing Facts About Raccoons.
Why possums are helpful
Before you reach for the broom, consider the positive: possums eat ticks, insects, slugs, and other garden pests. They’re like scruffy, nocturnal pest control walking your property for free.
They also clean up carrion, which reduces disease spread and keeps neighborhoods from smelling like the aftermath of a raccoon dinner party.
How to coexist safely
Living with possums is mostly a matter of common-sense steps that work for many backyard wildlife situations.
- Secure trash cans with lids and bungees so they can’t be tipped.
- Bring pet food indoors at night; feed pets inside when possible.
- Block off crawl spaces and gaps under porches where a possum might nest.
- Don’t try to pick one up—call a local wildlife rehabilitator if an animal appears injured or sick.

Quick dos and don’ts
- Do observe from a distance and enjoy the curiosity of a wild guest.
- Do secure attractants like pet food and fallen fruit.
- Don’t corner or try to handle a possum.
- Don’t assume every odd animal is rabid—look for unusual daytime aggression or staggering before calling for help.
If you spot a possum that’s acting strangely or is injured, contact a local wildlife rehabilitator or animal control. They’re equipped to help without stressing the animal.
