Opossums might seem harmless—maybe even a little cute—but have you ever wondered if they actually carry diseases that could put your family at risk? Honestly, opossums do carry some diseases that can spread to humans, especially if you handle them or come in contact with their saliva, feces, or fleas.
The risk isn’t sky-high, but it’s worth knowing what to look out for.
You might notice opossums rummaging through your trash or sneaking around your garden. That can make anyone a bit uneasy.
Understanding which diseases these critters carry—and how they can pass them to people—can help you keep your home safe without freaking out every time you spot one at night.
Diseases and Parasites Carried by Opossums
Opossums can bring in a handful of diseases and parasites that could affect you, your pets, or even livestock. The biggest risks come from their urine, feces, bites, or the bugs hitching a ride on them.
If you know how these illnesses spread, you can better protect your home and animals.
Transmission of Leptospirosis from Opossums
Opossums can spread leptospirosis, a bacterial infection, through their urine. You or your pets might catch it if you touch water or soil that’s been contaminated.
This happens more often in warm, wet places where the bacteria thrive.
Leptospirosis in humans usually starts with flu-like symptoms—fever, headache, muscle aches. If you ignore it, it can turn into serious liver or kidney issues.
Dogs are especially at risk since they love to sniff around outside.
To cut down your risk, stay away from standing water or wet dirt where opossums might have been. Clean up areas where they could urinate.
Salmonella and Food Contamination Risks
Opossums can carry Salmonella, which causes food poisoning. This usually happens if their feces or saliva contaminates food or water.
Since opossums dig through garbage and eat just about anything, they easily pick up and spread this bacteria.
It’s a good idea to keep pet food indoors or in sealed containers. Make sure your trash cans are tightly closed.
Try not to feed pets outside so opossums don’t have a reason to come close. Washing your hands after gardening or working outside is a simple way to lower your chances of picking up Salmonella.
Salmonella causes stomach cramps, diarrhea, and fever. Pets can get sick too, so if they seem off, check with your vet.
Bovine Tuberculosis: Regional Risks
Bovine tuberculosis mainly hits cattle, but it can sometimes affect humans and pets too. In some regions, opossums carry this disease and can contaminate feed or water.
This is more of a concern in places where opossums and livestock share space. If you keep animals, store feed in sealed containers and clean water sources often.
People with weak immune systems should be extra careful. It’s best not to handle wild opossums or their waste, especially in areas where this disease pops up.
Parasites: Fleas, Ticks, and Disease Spread
Opossums often have fleas and ticks that can spread diseases to you and your pets. These bugs jump from the opossum to whoever’s nearby.
Fleas can bring flea-borne typhus, which causes fever and rash. Ticks may carry spotted fever, which can get serious if you don’t treat it.
Opossums don’t usually get sick from these, but their parasites do the dirty work.
Protect your pets by using flea and tick preventatives. Try to avoid direct contact with opossums.
Wearing long sleeves and checking for ticks after being outside helps cut down on bites.
Opossum Prevention and Humane Removal
You can spot signs of opossum activity if you know what to look for. Acting fast keeps things safer and easier.
Getting rid of them sometimes takes professional help, but there are simple ways to make your home less inviting so opossums don’t keep coming back.
Signs of Opossum Activity Near Homes
Watch for odd droppings around garden paths, patios, or near the garbage. Opossum scat looks different depending on what they’ve eaten.
You might notice missing pet food or garbage that’s been messed with. These animals love outdoor pet dishes and trash.
Look under decks, porches, or sheds for nests made from sticks and leaves. Opossums like hidden, cozy places.
If you hear rustling or little animal sounds at night, an opossum could be nearby. Try spreading flour near entrances to spot their footprints.
Wildlife Removal Education and Professional Help
If opossums become a problem, you’ll want to know how to remove them safely. Live traps are common, but you shouldn’t relocate opossums on your own.
Most places require permits for wildlife relocation.
Wildlife removal pros know how to trap and handle opossums humanely. They have the right tools and know-how, so you don’t get hurt or break the law.
Experts can also show you how to keep opossums away for good. Hiring a professional saves you from headaches and legal trouble.
Home Safety Tips to Deter Opossums
If you want to keep opossums away, try making your property less appealing. Store your garbage in bins with tight lids.
Pick up fallen fruit from your yard. Bring pet food inside at night or keep it secured indoors.
Seal up any openings under your house, deck, or shed with hardware cloth. That way, opossums can’t sneak in and nest.
Stack your firewood neatly and keep it off the ground. Trim tree branches so they’re at least five feet from your roof—otherwise, opossums might use them to get on top of your house.
Put up a fence around your garden using wire and bend the top outward. Some folks add an electric wire above the fence for extra protection.
Motion-activated sprinklers can sometimes scare opossums away, at least for a little while. Give them a try if you’re feeling frustrated.
