Rats are clever creatures that can squeeze into tiny spaces and survive in our homes. If you’ve heard stories about rats crawling up through toilets and into homes, you may be wondering whether this can really happen.

In this comprehensive guide, we’ll provide a detailed look at the facts around rats and toilets.

The short answer is yes, rats can come up through your toilet, but it’s not that common. Rats are adept swimmers and can tread water for up to 3 days. They are also great climbers and can scale pipes and plumbing. With enough motivation, rats can emerge from sewer pipes into your toilet bowl.

However, there are ways to prevent this from happening.

Do Rats Live in Sewers?

Yes, rats are known to live in sewers. Sewers provide rats with a dark, moist, and sheltered environment, which is ideal for them to thrive. Due to their ability to squeeze through small openings, rats can easily find their way into sewer systems.

Rats Love Sewers

Rats are highly adaptable creatures that can survive in various environments, but they have a particular affinity for sewers. Sewers not only provide rats with shelter, but they also offer a constant source of food and water.

The waste that flows through the sewer system provides rats with a steady supply of nourishment, making it an attractive habitat for them.

Ideal Sewer Conditions for Rats

Rats prefer sewers that have a consistent temperature, typically between 60 to 70 degrees Fahrenheit. They thrive in environments that are dark and undisturbed, allowing them to build nests and reproduce without much interference.

Sewers also offer rats protection from predators, such as cats and dogs, which makes them feel safer in these underground habitats.

Rat Populations in Sewers

The exact number of rats living in sewers is difficult to determine, but it is estimated that there can be thousands of rats in a single sewer system. Rats are known for their rapid breeding capabilities, with a female rat being able to produce up to six litters per year, each consisting of around 6 to 12 offspring.

This means that rat populations can quickly multiply in sewers if left unchecked.

According to a study conducted by the National Pest Management Association, rats are prevalent in urban areas, with about 82% of pest control professionals reporting rat infestations in sewers. This indicates the significant presence of rats in sewer systems and highlights the need for effective pest control measures to prevent their spread to other areas.

Can Rats Swim and Climb?

Many people wonder if rats have the ability to swim and climb, especially when they hear stories of rats coming up through toilets. Let’s explore the swimming abilities and climbing skills of rats to better understand their capabilities.

Rat Swimming Abilities

Rats are actually excellent swimmers. They have the ability to tread water for extended periods of time and can even swim up to half a mile in open water. Their long and flexible bodies, combined with their strong limbs and tails, make them highly efficient swimmers.

Rats have been known to navigate through sewers and underground water systems, making their way into unexpected places.

Did you know? Rats can hold their breath underwater for up to three minutes, allowing them to explore underwater passages and reach areas that would otherwise be inaccessible.

Rat Climbing Skills

Rats are skilled climbers and can easily scale vertical surfaces such as walls, pipes, and trees. Their sharp claws and strong muscles enable them to grip onto various textures, giving them the ability to traverse even the most challenging terrain.

This climbing prowess is what allows rats to access areas that might seem unreachable to other animals.

Fun fact: Rats are capable of climbing up vertical surfaces that are more than twice their body length!

Rat Strength and Dexterity

Rats possess remarkable strength and dexterity, which further enhances their climbing and swimming abilities. They have a flexible skeletal structure that allows them to squeeze through narrow openings, making it possible for them to enter tight spaces, such as pipes and drains.

Rats also have a highly developed sense of balance and coordination, allowing them to navigate through complex environments with ease. This combination of physical attributes makes them incredibly resourceful when it comes to finding alternative routes and accessing new areas.

Did you know? Rats are capable of jumping up to three feet in height, showcasing their impressive athleticism and agility.

Rat Entry Points Into Your Home

Rats are notorious for finding their way into homes and causing havoc. They are agile creatures that can squeeze through small openings and are constantly on the lookout for food and shelter. To prevent rats from invading your home, it’s important to understand the various entry points they exploit.

Here are some common ways rats can gain access to your home:

Cracks and Holes

Rats can easily enter your home through cracks and holes in the walls, foundation, or even the roof. These openings may seem insignificant to us, but for rats, they provide a perfect entry point. It’s crucial to inspect your home for any gaps and seal them properly to prevent rat infestations.

Regular maintenance and repairs can go a long way in keeping these sneaky creatures out.

Pipes and Drains

Rats are excellent climbers and can use pipes and drains as a pathway into your home. They can enter through broken or damaged pipes, especially those connected to sewers or drainage systems. It’s important to regularly inspect your plumbing system for any signs of damage and fix them promptly.

By doing so, you can prevent rats from using your pipes as a gateway to your home.


While it may sound like an urban legend, rats can indeed come up through your toilet. This happens when there is a break in the sewer line or if the toilet pipes are not properly sealed. Rats are excellent swimmers and have been known to navigate through the sewer system and find their way into toilets.

To prevent this from happening, it’s essential to ensure that your toilet pipes are properly sealed and that your sewer lines are in good condition.

Risk Factors That Attract Rats

There are certain risk factors that can attract rats to your home. These include the presence of food sources such as uncovered trash cans, bird feeders, or pet food left out overnight. Additionally, cluttered spaces and overgrown vegetation provide rats with hiding spots and make it easier for them to access your home.

By eliminating these attractants, you can reduce the likelihood of rat infestations.

Preventing Rats From Coming Up Toilets

Rats are known for their ability to squeeze through tight spaces, and unfortunately, this includes your plumbing system. While it may seem like something out of a horror movie, rats can indeed come up your toilet if given the opportunity.

To prevent this unsettling situation, there are several steps you can take to protect your home.

Keep Toilet Lids Closed

One simple yet effective way to deter rats from entering your toilet is to keep the lid closed when not in use. Rats are skilled climbers and can easily maneuver their way up an open toilet bowl. By closing the lid, you create a physical barrier that makes it much more difficult for them to access your plumbing system.

Use Rat Screens on Plumbing Vents

Another vulnerable entry point for rats is through the plumbing vents on your roof. These vents allow air to flow through your plumbing system, but they can also serve as an open invitation for rats. To prevent this, consider installing rat screens on your plumbing vents.

These screens are designed to keep rats out while still allowing proper airflow.

Seal off Entry Points

Rats can find their way into your home through even the tiniest of openings. To prevent them from accessing your plumbing system, it’s important to seal off any potential entry points. This includes cracks in the foundation, gaps around pipes, and openings in walls or floors.

By taking the time to seal off these areas, you can significantly reduce the risk of rats making their way into your toilet.

Install a Toilet Flap Valve

One effective way to prevent rats from climbing up your toilet pipes is by installing a toilet flap valve. This device acts as a one-way door, allowing waste to flow out but preventing anything from coming back in.

With a toilet flap valve in place, rats will be unable to enter your plumbing system through the toilet.

Keep Drains Free of Gunk

Blocked drains can attract rats looking for a source of food and water. To discourage these unwanted visitors, it’s important to keep your drains free of gunk and debris. Regularly clean your drains and ensure that they are flowing freely.

By doing so, you not only prevent rats from being lured into your home but also maintain the overall health of your plumbing system.

Regular Exterminator Visits

While taking preventative measures is important, it’s also wise to enlist the help of a professional exterminator. They have the knowledge and expertise to identify potential rat entry points and take the necessary steps to eliminate and prevent infestations.

Regular visits from an exterminator can provide peace of mind and ensure that your home remains rat-free.

By following these preventive measures, you can significantly reduce the risk of rats making their way up your toilet. Remember, it’s always better to be proactive in protecting your home rather than dealing with the aftermath of a rat infestation.

What To Do If You See a Rat

Discovering a rat in your home can be a distressing experience, but it’s important not to panic. With the right actions, you can effectively address the situation and prevent further infestations. Here are some steps you should take if you see a rat:

Don’t Panic

While the sight of a rat may be alarming, it’s crucial to remain calm. Panicking can lead to irrational decisions and potentially worsen the problem. Take a deep breath and remind yourself that rats are a common pest and can be dealt with effectively.

Contact an Exterminator

One of the first things you should do when you spot a rat is to contact a professional exterminator. They have the knowledge, experience, and tools to safely remove the rat from your home and address any underlying infestation issues.

Don’t attempt to handle the situation on your own, as it can be dangerous and ineffective.

Disinfect Your Toilet

If you suspect that the rat came up through your toilet, it’s important to disinfect it thoroughly. Rats can carry various diseases and bacteria, so cleaning the toilet with a disinfectant is essential to maintain proper hygiene.

Additionally, make sure to wash your hands thoroughly after handling any contaminated areas.

Monitor and Seal Off Entry Points

After the rat has been removed, it’s crucial to monitor your home for any further signs of infestation. Inspect your property for possible entry points where rats can enter, such as gaps in walls, pipes, or vents. Seal off these entry points to prevent future rat invasions.

Remember, rats can squeeze through small openings, so it’s important to be thorough in your inspections.

Be Proactive with Prevention

Prevention is the key to avoiding rat infestations in the future. Keep your home clean and tidy, properly store food in airtight containers, and dispose of garbage regularly. Trim any tree branches or shrubs that may provide easy access to your home.

By implementing these preventive measures, you can significantly reduce the chances of rats entering your living space.

For more information on rat control and prevention, you can visit the website of the Environmental Protection Agency or consult with a professional pest control service.


While the thought of rats crawling up through your toilet is disturbing, take heart in knowing that this scenario is preventable. With some diligent monitoring of vulnerable areas, sealing off of entry points, and good sanitation habits, you can keep unwelcome rodents out of your plumbing.

Implement preventative measures, don’t hesitate to call an exterminator at any signs of rats, and you can rest assured knowing your toilet isn’t at risk of any furry intruders.
