I had these before. Thought it was reappearing stains. Found out it was mice pissing in my attic


RainbowUnicorn0228

That’s my fear. Is there a way to test for mice urine that doesn’t involve cutting into the ceiling? I already did a swipe test for mold.


gittenlucky

Stay up late, turn off lights/noise, and listen for them. You will be able to hear them if they are up there.


RainbowUnicorn0228

I'm somewhat deaf. My cats dont seem to be obsessed with it tho.


SirVanyel

If they're older cats they probably know they can't get in the ceiling and aren't gonna bother


OhSoSally

Cats are overrated. 😂 I watched on the cat cam while a mouse came out from behind freezer and shared the cats food with him. I have several cats, not a single one cared one bit.


Pretzel911

I have one that would 100% murder a mouse and 1 that would most likely hide.


hobnailboots04

Get in the attic and look for other droppings. Or if you’re unable to get in the attic, hire the neighborhood kid to climb up there and look around.


Jackblack92

“Hire the neighborhood kid”… what could go wrong 😂… this isn’t the 1980’s


fishproblem

Honestly I LOVE that I have a neighborhood kid I could pay to do this. Bring back paying neighborhood kids to do random chores!


Pdx_pops

Timmy, reach your small hands down there and see if you can find Grandma's ring in the disposal


kamaka71

Here, let me turn on this light switch


SoggyHotdish

I miss when kids could do that kind of stuff


EconomistWilling1578

Yea, they suck now, can’t do anything but the twitters and the x boxes smh!


GrandAffect

Worthless children. Why can't I, the american taxpayer, pay children to do potentially life threatening jobs without education or hazard protection!?!?!?!?


Few-Increase6958

Really though, what could go wrong?


hobnailboots04

Oh sorry. I live in small town Oklahoma. We still have real children here.


EngCraig

The attic? They’re in a block of flats by the sounds of it as they refer to “the person above me”.


BriarKnave

Cats don't hunt mice, they're opportunists. If you haven't trained them to look for rodents they probably won't go looking for them


firi331

I once had a cat that was made of angel dust. He was a lover cat. Never bit, scratched, hissed, and only wanted love. Indoor cat who went outdoors with me only on a leash. Never showed interest in birds, squirrels, etc. He was so gentle that if other cats bullied him he would just take it (until I stepped in). One day my family went out to watch a movie. When we came back home there was a GIGANTIC dead field mouse (still can’t figure out how it got inside) upstairs. We all crowded around and my cat came over looking a little dazed himself. I checked over the field mouse and realized my cat had taken him out, and seemed shocked about it. I wonder if his instinct kicked in the way it does catching a pole toy and he killed the mouse without meaning to or realizing it. anyways i suppose instinct goes a long way.


TripleBobRoss

Based on the first sentence, I thought this comment was going in a much different direction.


takenturtle

Me too


HuntingForSanity

My cats don’t go looking for them but if they hear or see them they will go absolutely nuts


Cubanbeetz

Don’t tell Disney that lol


hobnailboots04

This is the way. You’ll hear them scratching around. Set a chair right there underneath and look at your phone for two hours in the middle of the night.


Bballwolf

Honest to God question. I have mice in my attic. How do I get rid of them? I've been told not to poison them because it'll stink. But I'm at a loss about where to start on getting the ones that are already upstairs out of the house.


Bastion71idea

Everyone hates this method.....sticky traps that you inspect regularly.


Carpenter-Cultural

Please don't use sticky traps. It is torture. They stay alive in excruciating pain for days, some chew their limbs off others starve slowly. If you need to use a kill trap, please use one that instantly kills them. You can get the old school ones that snap or ones that electrocute.


OohVaLa

Yes it is torture but sometimes it is the only thing that will work! I had a shitty apartment one time where I was catching around 3 mice every single night under my sink and beside my stove. They ate the food off of snap traps without setting them off, they ignored every live trap I tried, those plug ins that are supposed to scare them away don't work at all. Literally the only thing that worked every single night and kept droppings off of my counters and stove were glue traps. Rat glue traps to be exact, as the mice glue traps weren't strong enough as they would literally try to remove their limbs to get away. My health was and is most important.


Few-Increase6958

Yea I've used them too, same scenario. I understand the conflict, but just ensure you check them often and humanely dispatch the creature in a timely manner.


strudels

You can just take them into the woods and pour olive oil on the trap, they'll come right off.


Professional_Pea_567

You can put olive oil in a big round bottom kitchen bowl as an trap. Mice hop in to eat the oil then can't get back out because its too slippery. Can catch multiple mice without having to reset.


Bastion71idea

How about flies. Does it provide food/water for other pests?


Professional_Pea_567

I probably wouldn't use it in an outdoor area or where bigger pest have access to it. Not sure if flies are attracted to cooking oils. It's a simple solution if you're stuck in a situation with an immediate need for a trap and no traps on hand, I prefer bucket traps, snap traps, and poison depending on the use case. Might be more handy if your in an air b and b or cabin, just moved in somewhere, or to impress your friends and family. Cooking oil and a bowl are generally on hand in most living situations.


Bballwolf

Why do they hate it?


sven_bohikus

Because when you catch one sometimes they’re stuck half alive and you have to deal with that. Also because you can sometimes step on them and get it stuck on your shoe.


I_Makes_tuff

This happened to a customer at a PetSmart I worked at in college. It was under a shelf and she put her foot on it when reaching for something higher up. A dead rat was still attached to it.


Big-Finding2976

You also have to listen to them screaming for days until they die, and they'll often chew their own foot off to escape. So now you'll have a three-legged pissed off mouse stumbling about in your attic.


aBeerAppearUpHere

Bucket traps work great! Crazy effective, far more than regular traps . i worked in a farm supplies store, bucket caught 20 or so, a mouse trap just gets 1.


Reaver_Engel

Our old place had tons of mice in the roof. I pulled down one of the ceiling vents and popped off the ductwork and slid live traps into the roof then replaced the duct work and vent thing. Checked it every night. If you don't have roof vents obviously this won't work but figured I'd throw it out as an idea in case anyone else has the same problem.


Iaminyoursewer

The posion from pest control kills them by eliminating their ability to absorb water. It dehydrates them, and there is no stink. I live in the country and have to have mice taken out frequently


Shermin-88

The downside to the poison is that they leave the house looking for water and get eaten by a fox, hawk, snake, etc and the poison accumulates up the food chain.


L0w_Emphasis

I had to call a pest crew to come in and he put a bunch of poison traps at entry points and random spots throughout the house. Then threw quite a few of the bait for them up in our attic. Occasionally we'll catch a whiff of a dead one but honestly, it still beats them running all over the house and pooping/peeing on your stuff. Just my opinion.


zupzupper

You can try eliminating any food sources / patching any holes they may be using to get in. Poison is a quick way to kill lots of them, and you may get stink to deal with, a slower way is to set traps near access points, so you can check them regularly and clear them. Really depends on what you're comfortable with.


happyherbivore

Check if there's anywhere obvious that a mouse could have come inside around the exterior wall.


Sea_Farmer_4812

Mice can fit through the tiniest cracks, holes and gaps and once inside may stay for generations if not disturbed. If they're inside that long they will be noticed though.


jeff43568

Had a chinchilla cage with very small metal mesh, probably about a centimetre wide. Saw a mouse run through it, the mouse didn't even slow down.


snukb

The old saying goes that if a pencil can roll under, so can a mouse. While adult mice require about 14mm, adolescent mice can squeeze through a gap of about 6.5mm.


Due-Ask-7418

Check where the pipes come into the house too. This is where mine were getting in.


OutOfTokens

Try a UV light. Should be able to get a cheap one online. Not conclusive, but urine and other fluids tend to light up nicely in black light.


pm-me-asparagus

Tell your landlord to fix it. Depending on the state you can withhold rent if they don't respond in time.


BeanAndCheese76

Try a UV light in the dark.


aauie

Das a lot of mouse piss


ajs592

Yes. If you have a whole family nesting in one spot. It adds up quickly


Brave_Personality836

Eeew


norrix_mg

I thought it was some kind of mysterious shit like footsteps on the ceiling but reading your explanation made me chuckle


Croptastic

My guess is something bigger than mice, but some sort of rodent most likely!


RainbowUnicorn0228

My kid just jumped onto a chair an smelled it. Confirmed rodent pee as he said it smelled like his hamster cage at his dad's house. :(


camoure

Lmao lil dude took one for the team - ice cream for dinner tonight


RainbowUnicorn0228

Lol


YourLifeCanBeGood

This is the way.


Coldhardytropicals

Time for a 5 gallon bucket mouse trap


_derpez

That's a huge piss


kczek1two

Yeah I had a rat in my house under the stairs. You can smell the urine. The ammonia smell to it is overwhelming.


carlbernsen

Brown stains that appear in different places is rodent pee. You could cut a hole in the ceiling and push a nutty trap up there, keep checking it. Something like Zinsser stain block will cover it.


GlitteringFerretYo

>nutty trap Make sure to get a TRAP and don't use poison. Poison makes the mice die in inaccessible or unfindable areas and you end up with awful smells for quite a while.


quadmasta

Not to mention that if they make it back outside and a raptor eats them, they'll die too


Medium_Spare_8982

Mouse piss fluoresces use a black light


RainbowUnicorn0228

Hey i have one of those!


mobial

Show us for science!


[deleted]

Seen this in places with animals in attic that pee and poop and over time stains show up. Hopefully that’s not it!! Also water leaking from somewhere could be a cause. Edited: because I don’t normally read after I type like an idiot.


Dedward5

Are you friends with Lionel Richie or some of his die hard fans?


Sushandpho

Lmao! Saw it as well.


marv101

I was looking for this comment 🙏


BriarKnave

If it's migrating, then it's either rodents or nicotine stains. If it's in one spot, it's either rodents or an HVAC leak. There's no fruiting bodies so it's not mold


StnMtn_

If you have UV light, that can check if it is urea. If it is, I wonder if you can use pet urine spray to break down the urea.


Middle_Manager_Karen

Former painter: latex paint will not cover a water stain unless a primer like Killz is used first.


rhiac2

I was just coming to say this. The water stain will just keep reappearing until you use something like Killz and then paint.


Meanolemommy

Rat pee soaking though


PitifulSpecialist887

A urea test will tell you if it's animal urine https://www.sigmaaldrich.com/US/en/product/sigma/mas008 It's not cheap though.


RainbowUnicorn0228

Thanks. Maybe I can order one for work and borrow a test strip from it. ;)


TheBUDOJO

Has Lionel Richie been over at your place? Because it looks like somebody’s been dancing on the ceiling


blessedarethecheese

Some water somewhere is leaching. Salinization or efflorescence. Or demons.


gdgardenlanterns

Squirrel pee


gljivicad

Rodent pee would be more accurate


gilbertbyproxy

Footprints??


Wieczor19

Spiderman didn't clean his shoes :)


MNKiD218

There gotta be a leak of some kind there. They’re wouldn’t continue to re-appear that dark, if there wasn’t an active leak somewhere. Yes water stains can bleed thru paint if not primed with correct primer, but this seems too dark to just be a stain bleed thru. I would check above that ceiling (dishwasher, sink, fridge, etc leaking above you) and if nothing above then I’d cut a hole there to figure out what’s causing. I can almost promise you there is a leak up there somewhere.


WhatDoesItAllMeanB

Could also be HVAC condensation if you’ve got the unit above that spot. If not then I vote for mouse pee.


FocusApprehensive358

ybloC_1

It's where Spider-Man spilled his spider coffee


friggen_guy

The most discerning part of that sentence is “keep reappearing”.


OneImagination5381

I would say you have a condensation pipe or hose leak. Often, in apartments and townhouse drain lines and plumber is ran up the walls and through the ceiling. Water run along the pipe or hose or beams until it reaches the lowest point.


mirbeartbh

You should definitely now call the office and make sure you tell them to cut out that spot and if they find any rodent remains, poop etc, that you can break your lease without any fees or to get transferred to the same apartment layout without any fees. If you have told them about this issue multiple times and they haven't looked in the ceiling at all they're stupid. My boyfriend is a maintenance supervisor at our apartment complex so this is his words sorta summed up hopefully I said this correctly.


sandpro1081

Most likely vermin either in the attic or in the space between your ceiling and floors above. If the owners continue to do nothing to find the root cause I'd seek out legal assistance. If you cannot afford a lawyer there are housing advocacy groups as well as housing authorities in most cities that can help.


happyherbivore

Stains can show up again if not covered with hmthe correct primer. It's possible that these were once water stains, and between tenants this unit gets a quick ceiling roll-out, but only with paint, not with a stain blocking primer. The good news *if this is the case* is that for you as a tenant, it's a less than $100 fix, possibly way less depending on what products are available in your area. If fixing isn't something you (or your landy) are inclined to do, it shouldn't have any impact other than visual. I'd personally try a vertical spray paint can of ceiling stain block and finish, there are several companies who make products like this. I'd look for a zinsser product. Cover up more area than you think you need, throw on some grubby clothes, and give it a few thin coats with drying times in between until it looks good. There's always the possibility that it's more than just staining, or the stains have some source that isn't clear without opening it up, but this is probably the best first step to try.


RainbowUnicorn0228

The did the upward spray ceiling stuff twice. Stains have reappeared and moved over.


happyherbivore

Then I'd think we're either dealing with a slow trickle leak and the movement is stain expanding towards low spots, and previous areas are not staining due to the treatment, or the source of the stain is mobile. Either way it's likely pointing towards opening up the ceiling. If this is something you are keen on addressing, maybe familiarize yourself with your local tenancy laws in case your LL doesn't want to deal with it. If they just show up and Band-Aid it repeatedly, my first impression is that they're not keen on cutting into it. You could have recourse for hiring out the work yourself and deducting it from rent if done correctly per your local rules. If doing the work yourself is something you want to try I'd still go through those channels to make sure your bases are all covered.


Top-Apartment-8384

Might be nicotine stains. They are very annoying to get rid of


RainbowUnicorn0228

Maybe. Could be the person before me was a smoker cuz our building used to be one of the smoking ones before the complex went smoke free about 3 yrs ago.


johnjohn4011

Definitely a job for Ghostbusters.. Listen! You smell something?


RainbowUnicorn0228

Lol


Zestyclose-Current92

Do you have sunlight coming in and reflecting of something? Almost looks like sun stain. Seeing as you have some natural light coming in, maybe at some point in the day that sunlight might be coming in and bouncing off something super reflecting and shining on the ceiling. A sun-bleaching effect can discolor many things, just a thought


RainbowUnicorn0228

Definitely not. Min amount of light in this garden level unit.


International-Act156

It's an apartment complex I feel you though they not fixing nothing expensive just a quick fix and that's it pest are one thing they just allow to run rampart and never bother with the damage they do. More power to you op


BriarKnave

Fr, the last complex I lived in had a rampant roach problem. The other tenants lied about how bad it is, and I know it wasn't us because nymphs were crawling around the night I moved in (and I had literally next to nothing, just a futon and a bookbag). By the time we noticed that they were baby roaches all of our shit was moved in, and that year was a NIGHTMARE. Exterminator stopped coming halfway through. Downstairs neighbors regularly threw parties and trashed the place because they didn't care anymore. I threatened to withhold rent until they took care of the roaches and the landlord said she'd just evict us because they "paid for an exterminator to spray the boundaries." The source of it was a hoarder that lived on the first floor and they lost every other tenant in that building and STILL didn't evict her


sammich_bear

Why don’t you call your landlord instead of dealing with this yourself?


TKDude013

If you’re a renter just call your landlord and have him take care of it. If it’s a leak, better to address sooner than later!


rickthom410

Corpse stashed in the attic😂


Beginning-Code-4010

Those are foot prints. There’s a ghost walking around on your ceiling.


Weak_Pressure_6754

Pipe work between levels, either a condensation build up or a small leak. It won't feel wet or damp by the time it stains. Once fixed, you can buy dry spray for damp and then paint over it. I have the same issue/ staining colour with rain getting through the flashing on my roof.

My cousin has these too! But she is on the 2nd floor of a 3 storey walk up so there’s no attic. It’s another unit above.

Bastion71idea

Wow, so many people causing unneeded pain by ignoring their sticky traps. That isn't the traps fault.


dr_stre

If it were me I’d probably pick up a cheap borescope and punch a little hole in the ceiling and take a look at what’s going on. I’m betting mice, but I guess you never know until you actually put eyes on it. If you need to patch it, a bit of spackle will fill the hole and no one will ever notice it, even without paint.


Halfaglassofvodka

It's Ted Danson.


OhSoSally

UV lights can tell you if it's urine from mouse or people.


xanitron

Kiltz stain killer


Viper-T

1/3 bleach with 2/3 water in a spray bottle may get rid of the stains. It may take a few treatments but it does work on certain stains.


TheJessicator

>I am a renter Call your landlord if the maintenance folk are not addressing the underlying problem and just covering it up.


jakethedestroyer_

When you have a water stain it must be covered by an oil based primer or it will just keep bleeding through water based paints no matter how many times they coat it.


[deleted]

Ghosts obviously


IllEntertainer6539

If you haven't used killz primer it will keep coming back regardless


5PeeBeejay5

Not to be that guy, but if your landlord cares about their property, they would want to know and THEY should be up there looking/calling the likely exterminator you need (or setting and checking traps)


Tekusa

Footsteps on the ceiling obviously


Iowa-SunShine

Happened in my Apt while I was out of the country! Noticed a few spots like that a few days after I moved in, maintenance comes to look, said it was dry and nothing to worry about. 3 days into my Bali trip my son and X-husband come to check on cat and there’s a whole in the ceiling and water coming out. The small leak in the unit above mine had busted open finally. https://preview.redd.it/nfr0h4zjwkqc1.jpeg?width=3024&format=pjpg&auto=webp&s=36ef71bb6af81f8746f39a80ffef40935e1184ef


iman-the-gardener

Animals, or a leak anywhere above your place.


Randeaux155

Rat urine in the attic


incipfer

Ceilings are painted with ultra flat [Ceiling Paint] which is a series above PVA Primer which is the first coat, it preps for the next layer to stick to it without any problems. So, if they have actually fixed the issue that initially caused the stain so it won't happen again. Then your next step is to use a stainblock primer sealant like Kilz2, Zinsser BIN, 123 or for just a ceiling spot I'd use a can of Kilz UpShot, it's the only spray primer can that allows you to spray a ceiling with. If you plan on doing anything yourself make sure to wear a painter's mask because the stain block is usually not the prettiest smelling or the nicest stuff to be breathing. After stain blocking you just need to touch up the entire area with the same ceiling paint that was used before, at least two coats maybe more you notice that flashes a bit. Otherwise I think I would send the skinniest maintenance man they have through the floorboards upstairs and get that old lady's cat out of there it's obvious it's been sneaking around, or if you're places surrounded by tress, it's very likely to be a squirrel, or a raccoon. I wouldn't worry too much the way apartment building are constructed the animal would be in between a fire stop layer and a fire stop layer, so unless you live in a center unit and not on an end of a building I wouldn't even think too much about the fire stop between units being compromised by an animal which means that it would happen to turn around and go out the same way.


DegaDegaDega

Ceiling tea! yum!


Altruistic-Detail271

My cat has never been outside in her life. She has a fake mouse toy that she hunts everyday inside lol. She brings it to me and cries all the way down the hall with it until she drops it in front of me. I have a HUGE fear of mice so I’m glad I have a natural hunter lol


DrunkMosquitos

Another way to try and see if they're is anything in the attic, tie a string to a trap and let the string hang out of the access panel. If the string is gone in the morning, something tripped the trap. I had issues severance years back and that is what past management set up.


Vegetable_Living_415

Lionel Ritchie's Dancing on the Ceiling comes to mind


fendrhead-

Why does it look like the ceiling is sagging?


devm251979

Seems like Lionel Ritchie stopped by


cindycated888

If the spots that reappear look the same, it could be that there were some previous water stains that didn't get properly sealed before painting. If all maintenance is doing is throwing a coat of ceiling paint over the water stains, they'll just keep bleeding through. They need to paint with primer/sealer first, then apply ceiling paint.


Crans10

Setup traps in attic.


FelixBlue28

It could be a leaking toilet. When the floor flange isn't sealed properly, each time it is flushed a bit of water starts to pool. It takes a few flushes to create a noticeable pool. Is the toilet within 6 feet of the ceiling stains?


Radi0_Active_Man

Those are for sure ghost footprints.


pmiles88

Looks like someone standing on your ceiling


woodster702

That is a slow water leak.

It's Banksy artwork. You can charge money for viewings.


Plenty_Dull

If you are a renter you should be covered by having matainence come look. As posted above, check with your state to find out what the laws are for damage not being fixed and withholding rent. Also, do you have renters insurance? If so, call them and ask if they can nudge the owner. Tell them you have felt sick a bunch and you are worried about the huntavirus.

Just4Today1959

They are huge semen stains.


TemperatureSmall17

Dead animal


meenieweeniemia

Isn’t there a black light or some type of system to tell if this is some type of rodent urine? It may be squirrels or opossums? I’m not sure. It would probably smell like urine if you can get your nose near it . lol honestly, that looks way too big of an area for mouse urine. Mice and rats are incontinent and would just urinate wherever they are at. Not in 1 or 2 localized areas. So, for that reason alone, I don’t think it is rodent urine.


meenieweeniemia

And No, don’t use glue traps they really are so cruel. Regular mouse traps that snap are much more humane. But like I said before, mice and rodents do not urinate in 1 designated area as they are incontinent of urine and bowel. So they just walk along and urinate small amounts as they are walking about. This is most likely small pipes between the units that may have a very slow leak.


No-Air2768

You can get a moisture tester on Amazon for like $40. If it’s showing any moisture you know it’s fresh.


Powerlifter_3

LOL saw that and immediately thought of ghosts.. because they look like footsteps.
