So, you walked into the dark and saw two glowing eyes staring back from the rafters, and now you're wondering how do you get a possum out of your garage without causing a massive scene. It's a bit of a shock, isn't it? One minute you're just trying to grab a screwdriver or head out for a grocery run, and the next, you're face-to-face with a critter that looks like a prehistoric giant rat with a bad attitude.
The good news is that while they might look a little intimidating with those fifty sharp teeth and beady eyes, possums are actually some of the most misunderstood creatures in the neighborhood. They aren't aggressive by nature, they're almost immune to rabies, and they do a fantastic job of eating ticks and garden pests. But that doesn't mean you want one living between your mountain bike and your holiday decorations. Let's talk about how to get them back into the wild where they belong.
Give them a clear exit and a reason to use it
The easiest way to deal with a possum is to let them handle the move themselves. Possums are nocturnal, which means they're mostly active at night and looking for a quiet, dark place to sleep during the day. Your garage, with all its clutter and corners, is basically a five-star hotel for them.
If you've spotted one, the first thing you should do is open the big garage door about an hour before sunset and leave it open until well after dark. Most of the time, once it gets dark, the possum is going to want to head out and find some snacks. If the door is wide open, they'll just waddle out on their own. Just make sure you turn off the lights inside the garage so they feel safe enough to move. If it's too bright or noisy, they might just hunker down and wait for "the threat" (you) to go away.
Change the atmosphere
If the "open door policy" didn't work after a night or two, you need to make your garage a lot less comfortable. Possums love peace and quiet. If your garage suddenly becomes a loud, bright, smelly nightclub, they aren't going to want to stick around for the after-party.
Turn on the lights. Put a bright shop light or a few floor lamps in the garage and leave them on 24/7. Possums hate bright lights because it makes them feel exposed. Pair that with a radio. Tune it to a talk-radio station—not music, but human voices. To a possum, the sound of humans talking sounds like a predator is nearby.
You can also use scents to your advantage. Possums have a very keen sense of smell, and they aren't fans of anything too pungent. Some people have great luck with bowls of cider vinegar or rags soaked in ammonia (just be careful not to breathe those fumes in yourself). Place these near where you think the possum is hiding. It's a gentle way of saying, "Your stay here is over."
Don't fall for the "playing dead" routine
If you happen to corner the possum or startle it, there is a very good chance it will "play possum." This isn't just a funny phrase; it's an involuntary physiological response. They basically faint from stress. Their heart rate drops, they go stiff, and they can even emit a foul smell to make it seem like they're decomposing.
If you see a "dead" possum in your garage, don't just go pick it up with your bare hands. It's likely very much alive and just waiting for the coast to clear. If you find one in this state, the best thing you can do is leave it alone for a few hours. Give it a clear path to the door, walk away, and check back later. Once the stress wears off, it'll wake up and realize it's time to leave.
Use a one-way door
If you've figured out exactly how the possum is getting in—maybe a hole in the siding or a gap near the floor—you can use a one-way exclusion door. You can buy these or even make one if you're handy. Essentially, it's a flap that allows the animal to push through to get out but won't let them push back in.
This is a great long-term solution because it ensures the animal is out before you seal the hole permanently. Just a quick word of caution: before you seal anything up, make sure there aren't any babies left behind. Possum mothers carry their young in pouches, but as they get older, the babies might fall off or stay in a nest while the mom goes out. If you hear tiny clicking or hissing sounds, you might have a family situation on your hands, which makes things a bit more complicated.
What not to do
When you're trying to figure out how do you get a possum out of your garage, it's just as important to know what not to do.
- Don't use poison. It's cruel, it's dangerous for your pets, and if the possum dies inside your wall or behind a heavy workbench, you're going to have a smell in your house that you will never forget.
- Don't try to corner them. Even though they aren't usually aggressive, any wild animal will bite if it feels trapped and terrified.
- Avoid using your bare hands. Even if you're wearing gardening gloves, a possum's teeth can go right through them. If you absolutely have to move one physically, use a large plastic trash can. Tip it on its side, use a broom to gently nudge them in, and then tip the can upright and put a lid on it.
Why did they choose your garage anyway?
Getting the possum out is only half the battle. If you don't change whatever attracted them in the first place, another one will likely move in next week. Possums are opportunistic. They are looking for two things: food and shelter.
Check around your garage for any food sources. Do you keep your dog or cat's food out there? Is your birdseed in a bag that isn't sealed? Do you have a trash can without a locking lid? To a possum, that's a free buffet. Move all pet food and birdseed into metal bins with tight lids.
Next, look at the structure itself. Walk around the outside of your garage during the day and look for gaps. A possum can squeeze through a hole much smaller than you'd think—anything about the size of a baseball is plenty of room for them. Use hardware cloth (a heavy-duty wire mesh) to cover vents and fill in gaps with expanding foam or lumber.
When to call in the pros
Look, I get it. Not everyone wants to spend their Tuesday night playing cat-and-mouse (or man-and-possum) with a wild animal. If you've tried the lights, the radio, and the open-door trick and that possum is still staring at you from the rafters, it might be time to call a professional wildlife relocation service.
They have the right traps, the right gear, and the knowledge to handle the animal safely. Plus, they can often identify entry points you might have missed. It costs a bit of money, but for the peace of mind of knowing the critter is gone—and that it was handled humanely—it's often worth the investment.
Wrapping it up
At the end of the day, having a possum in the garage isn't the end of the world. They aren't there to destroy your house or attack your family; they're just looking for a warm place to nap. By being patient, making the environment a little less welcoming, and ensuring they have a clear way out, you can solve the problem without any drama.
Once you finally see that tail disappear into the night, take a deep breath, seal up those holes, and maybe keep the garage door shut next time you're working in the yard. It's a lot easier to keep them out than it is to convince them to leave!
