When I was living in the apartment about 25 years ago, a possum moved into the laundry room in the basement in the back of the building. Luckily, I was in the front.
It dropped a litter. The landlord tried to rent mostly to coeds from the major universities, and they thought the babies were just so cute...
And then people in the back of the building started getting fleas.
Suddenly, it was "make the bad vermin go away!"
Now, I wasn't the landlord, but I would do things for neighbors. Install better locks, etc... I think they thought I was some sort of "do anything" person. A couple of them had seen me carrying rifle cases, so when we had an urban outdoorsman move in to the boiler room, they asked me to get rid of him... I told them that that wasn't really what I did, called the cops, and then went downstairs and told him that they were on the way. He moved to a different building...
Anywho...
And some of the former possum supporters asked me how they could get rid of the things. So I told 'em to go to the hardware store, and buy traps...
I think they did one, and then took it a few blocks away to Forest Park, and let it loose.
So... I started looking for baby possums occasionally. Bam with a trenching tool (compact, easy to swing, carry outside, into the dumpster... Did it subtly, after I got home from work at night.
Coupla days later, about all that is left is Mama Possum, and one of the tenants knocks on my door, and says that they have her cornered in the laundry room ceiling. Okayfine. I go down to take a look. Yup, she's there, and she's going to be hard to get to. But I knew just the ticket. Went upstairs, grabbed one of those 18" bayonets, stuck it on a Mauser, and went back downstairs. Well, by that time, there was a half-dozen tenants in the laundry room, including the gay guy couple. And when one of them saw the Mauser, eyes rolled up, and he fainted dead away... So I explain that I only mean to prod the critter toward the door, and they drag him upstairs...
At which point with no witnesses, I gigged Mama Possum, and put her in the dumpster.
