What is the worst/creepiest/weirdest stuff you have seen in an apartment?

Robert Garcia sent me a link to this discussion on Reddit asking what the strangest things people have seen when going into an apartment. Some of the answers were gross, and some just sad, as it's clear there were some mental issues, addiction issues, etc. Here were some interesting ones:

I was doing some work with an engineering firm and there was a lady who was complaining about severe moisture and water build up in her apartment. After checking with all the other apartments around her and nobody else complaining we went to investigate.

We knock on the door and the second she lets us in we are hit smack in the face with a wall of humidity. I mean like standing in Vietnam during monsoon time humidity. Its hot, extremely humid and just walking 5 feet in youre already saturated with water.

We start the investigation and notice her carpet is soaked everywhere. Just squish squish squish as we walked through. I get to her sliding glass doors to her patio and no word of a lie there are 2' tall mushrooms growing out of her carpet. The water built up so badly on the glass doors and dripped down onto the carpet she had a 10' x 10' mushroom garden growing.

Turns out the cause for it was found when I opened her closet. She had her son sneak in a clothes washer and dryer one night and 'installed' them into her closet without having proper plumbing for the washer and absolutely no ventilation for the dryer. So all the humidity from the dryer and washer were trapped in the apartment.

I had to crawl under this woman's duplex to run a wire. In her living room she had 4 dogs in a cage that was nailed to the floor. Under the floor in the same spot were stalactites from where the dogs had been peeing over the years.

Insurance salesman in Detroit, here. I've seen a lot of disgusting places, hoarders, and people so poor they can't afford cleaning supplies.

Anyway, one story really sticks out above the rest. I was at this woman's apartment once to go over her Medicare and social security benefits, she lets me in and before I even get to the living room, this awful smell hits me like a brick wall. It was seriously the worst smell imaginable. I kept telling myself just to get acclimated to the smell and once I do that, I'll be good. So I'm trying my hardest to do just that, meanwhile we walk over to her living area and have a seat on the couch.

Before I go on, I should mention that there is a weird white residue on everything in the house, at first I thought it was dust, but I'll get to that in a minute.

Anyway, she ends up buying a life insurance policy for herself and I'm writing up the application. Meanwhile, I'm sweating my ass off trying to keep my cool because they smell still hasn't gotten any better. I must have looked off or something because she finally asked after about an hour of me being there, "Honey, does it smell in here?" I politely said "well, just a little." So she said hold on and disappeared into the back.

As she's back doing whatever she's doing, I happened to notice something on the other side of the couch, over in the corner. It was a bucket. A bucket with a bag in it, and all kinds of other bags nearby, sitting on the floor. Curious, I took a good look at it and realized this is...this is where she goes to the bathroom.

Rather than throwing the bags of poo away after she was done, she'd throw it in the corner and call it good. Now I feel like throwing up. Just then, I see her shuffling down the hallway, heading back to where we were sitting and she's carrying some yellow box with her. She looked at me and said "You're going to want to get up for a second, sweetie." So I grabbed my bag and stood behind her.

Then, she takes the yellow box of what I can now make out as baking soda, and flings it across the whole room, which is where the white residue came from apparently. I couldn't hold my tongue, I was in such disbelief I think I actually said "no s***..." In front of my client. She was taking craps in a bucket in the corner, leaving the bags of feces in the room, and when the smell got to be too much, she'd throw baking soda at it.

Wow, thats pretty rough!
The absolute worst I've ever seen involved so much ICK, I had to stop at a convenience store on my way back to the leasing office and wash off...
The baby's crib had dirty diapers piled up, the toddler bed had sheets stained with pee. There was dirty clothes covering every inch of the floor, mixed in with diapers- and one got stuck to my shoe! The cats were inside but there was no litter box to be seen, and plenty of feces on the bathroom floor, the dogs lived in the garage and the smell was HORRENDOUS!

Here I thought I'd seen some creepy and nasty stuff and all of this has me topped. I can count my blessings. The worst I ever saw was bloody tattoo needles. The apartment had seemed empty for at least a week or two. The resident's "sister" called to say that the resident had been with her and had died. She also told me to call their mother (in another state) and inform her of the death! I called the mother, cautiously, who said the resident had no sister and the resident was right beside her. Then she said turned away from the phone and said, "Honey, what are you up to now?"

This is going to be a fascinating topic.
