Most people know the dangers of rat infestation, so they take prevention steps, such as blocking cracks and holes, keeping food in containers, etc.
Unfortunately, rats always find a way into people’s properties. They’re a challenge even for rat control experts because they’re intelligent.
Most people don’t know, but rats can swim. Studies say they’re excellent swimmers who can paddle for three days in laboratory conditions.
Moreover, rats can hold their breath for up to 3 minutes. So, it’s true that rats sometimes swim through sewer pipes, fit through plumbing, and pop up in people’s toilets.
Below, you can find more interesting information about rats and their swimming abilities, so let’s dive right in.
How Long Can Rats Hold Their Breath?
Experts suggest that rats can swim. I’ve confirmed your worst fear–a rat in your toilet.
As if making sure these rodents can’t access your house by land, now you should worry about the water-based weaknesses of your property.
Furthermore, rats aren’t average swimmers. On the contrary, some species of rats have strong swimming capabilities. They can also hold their breath underwater for up to three minutes.

The studies claim these rodents can swim for three days, as most rats in urban habitats spend most of their life in water. Rats can also navigate the complicated sewer systems, typically below cities.
Some species of rats can even hunt in rivers and other bodies of water, including water systems.
Like most rodents, rats eat and drink daily. Therefore, they’re in constant search or hunt for food. If they find their food sources removed, they will take desperate measures, like swimming through sewer systems and climbing sewer pipes.
That’s how rats enter people’s homes through toilets.
How Long Does it Take for a Rat to Drown?
Rats can’t breathe underwater. They can swim for several days and hold their breath for three minutes. However, they drown like most rodents very quickly.
When rats swim, they keep their head above water to breathe. Therefore, they can’t last long underwater; they would die within seconds or minutes.
However, the professional pest control industry, the government, and scientists suggest that killing rats isn’t humane.
So, if you have a rat infestation or captured rats, don’t take matters into your hands. Instead, contact the pest control experts for help.
How Long Can Rats Survive Without Air?
Rats can live without air as much as any person or animal.
Humans can typically survive about three minutes without breathing air. However, if you saturate your body with oxygen before you stop breathing or increase your lung capacity through exercise, you can survive a little longer without air.
Now, imagine you’re a small rodent in a large container. You would survive until you use up the air in your surrounding space.
I can’t say the same for naked mole rats.
Studies claim that naked mole rats can survive for about five hours at low oxygen levels. Humans would die in minutes at such low oxygen levels.The latest studies suggest these rats apparently can handle up to 18 minutes without oxygen by entering a type of vegetative state.
How Long Can a Rat Survive Underwater?
Rats can swim through bodies of water for three days without rest, but they can’t survive underwater for long because they can only hold their breath for three minutes.
Moreover, some rats swim better than others.
For instance, black rats prefer the land. So, if you see black rats in your home, they probably arrived on foot. On the other hand, marsh rice rats can swim very well and find most of their food in the water.

Luckily, marsh rice rats usually live in swamps and consume small fish and crabs. They don’t invade people’s homes because they find their food source in nature.
Have you heard of brown rats? They’re excellent swimmers known as “water rats.”
Unfortunately, brown rats can swim well and carry many diseases and pathogens. The worst part? They can easily find a way into your property.
If you suspect you have brown rats in your bathroom, attic, or walls, contact experts for help immediately. Most rats increase their population quickly, so you should take action before they multiply in your home.
How Long Can a Rat Survive Without Food?
Most rats can survive for 1-2 weeks without any food. However, like squirrels, rats store food. So, even if you block their food source, they would still have food and survive for a while.
There aren’t studies confirming how long these rodents can last without food and water. Still, some studies suggest they can’t survive for more than two weeks without food and water.

Closing Thoughts
Most rats learn to swim at a young age. That’s why they’re excellent swimmers and can hold their breath for three minutes, but that doesn’t mean they like swimming.
You can’t tell if they enjoy swimming because they typically swim when looking for food. Pest rats, for instance, swim when they can’t find food on the ground.
Swimming is a part of their survival strategy. That’s why pet rats can’t swim; they have food and shelter and don’t need swimming skills.
Why Do Rats Swim?
Rats in sewers usually swim long distances to find food. Moreover, rats in the wild swim when escaping predators; they can swim for hours if running by land isn’t possible.
Some rats can climb ships and cross rivers to reach new territories. Although they don’t have webbed feet or fins like naturally aquatic animals, most rats swim excellently.
You can see rats in canals, lakes, and even oceans in big cities like Paris, London, etc. Statistics say even major cities have high populations of rats.
As you can see, swimming isn’t their only strength. They’re versatile rodents with strong survival skills. They’re also known for invading people’s homes.
Can a Rat Swim Out of the Toilet?
In short, rats can reach your home in many ways, including swimming through sewer systems and climbing plumbing pipes.
So, don’t hesitate to call rat control experts if you see one in your toilet. Otherwise, you might experience a rat infestation in the future.
Avoid handling rats yourself because they carry diseases and pathogens. Only people with experience in rat extermination can successfully eliminate these rodents. Some sources even suggest that rats like human blood.
