Can Rats Come up Through Toilets
著者: 森 瞳
So, how does a rat decide to take the scenic route to your bathroom? It usually happens when the sewer system gets overcrowded. If a colony gets too big, the younger rats go exploring for new territory, and your toilet pipe looks like a dark, mysterious tunnel. And we all know what happens when you give a rat a dark tunnel—they’re going to explore it.
Another reason is broken or missing sewer traps. That U-bend under your toilet is filled with water to block smells and critters. If that seal is broken, it’s like leaving the front door open for a furry intruder. Rats are also great climbers, so if your toilet is on the first floor, they’re more likely to take a stab at it than one on the tenth floor.
And let’s be real—rats are braver than we think. They’ll sometimes brave the chlorine and the darkness if there’s a food source on the other side. No, they’re not coming for you. They’re coming for that floss you dropped on the floor last week. Yes, rats love floss. Don’t ask.
What Are the Chances, Really?
Okay, let’s put this in perspective. A 2017 study in New York City found that only three out of 5,000 rat sightings were in toilet bowls. That’s a 0.06% chance. You have a higher chance of getting a free soda from a vending machine than seeing a rat in your toilet. So you can basically flush that worry away—pun absolutely intended.
But if you still feel nervous, ask yourself this: when was the last time you heard a friend say, “Hey, a rat came out of my toilet last night”? Never, right? That’s because it’s the kind of story people tell at parties, and it’s so rare it becomes legendary. It’s the Loch Ness Monster of bathroom horror stories.
Still, the internet loves to scare us with viral videos. You’ve seen them—a rat popping its head out of the water like a derby-ready submarine. But those clips are from homes with septic system issues or abandoned buildings. Your well-maintained toilet is a fortress compared to that.
