How Do I Get Rid of Rats in My Sewer Pipes?

  • by

Rats can live anywhere there is food and shelter. And sewer and drain pipes provide the best habitat for them.

You may be wondering how they do it, but here’s how. Rats can enter the sewer and drain pipes via a tiny drainage system crack.

Once they gain access, they will make this place their home because sewer pipes provide them with food, shelter, and water.

They will live inside these pipes, constantly moving to find new places as they traverse the pipe system. This is how they find their way into your toilet bowl, bathroom drain, or kitchen sink.

In this Post, we will cover:-

Do rats actually live in sewers?

In fact, sewer pipes provide an ideal habitat for rats. This is because sewer pipes offer them all the necessities they require, such as warmth, food, and water, as well as a safe haven.

As a result, it is estimated that more than one million sewer rats are living in the sewer piping systems of all domestic properties.

Can rats come up through drains?

Rats can make unwelcome appearances in your toilet bowl because, unlike the kitchen sink and bathroom drain, the toilet drain provides easy access.

Kitchen and bathroom drains are fitted with filters and drain stoppers that help prevent rats from entering, unlike the toilet bowl, where the rat must pass through the S-strap. A rat will have no trouble navigating the toilet bowl.

That’s why rats are more likely to be found in your toilet bowl than in your kitchen sink or bathroom drain.

What to do if a rat comes up the toilet?

If you find a rat inside your toilet bowl, suffocating it is the simplest and most effective way to get rid of it.

Pour bleach into the toilet bowl and close the lid for 2 hours. As a result, the rat will be deprived of the oxygen it needs to breathe.

Pick it up by the tail and put it in the outside bin while wearing protective gloves. Rats should never be flushed down the toilet because they can clog the S-strap and cause more harm than good.

Can rats enter house through toilet?

The answer is no, and here are some reasons for this frequently asked question.

Since the S-strap curves prevent big rats from crawling through, most mice that make their way through the turns are small and more likely to drown in the toilet bowl water.

Toilets typically range in height from 22 to 34 inches. This is too high for a rat to climb through the toilet bowl, making it highly unlikely that the rat will reach your bathroom through the toilet bowl.

Finally, toilet bowls are made of porcelain or ceramic, a shiny, non-porous, and easy-to-clean material. The toilet bowl’s glassy surface will make it difficult for rats to climb through. This is due to the glassy surface working against the sharp claws.

Call your local Plumber

A final, more expensive option is to hire a plumber to inspect all drains and sewers for cracks and holes that rats can enter.

What smell will keep rats away?

Because prevention is better than cure, we’re all looking for ways to keep rats out of our bathrooms and homes.

Due to the fact that rats do have powerful senses of smell, there are certain scents they do not like and this is a good thing as they will avoid those smells, thus keeping them away from your bathroom, home, and garden.

Here are the most effective scents that rats normally hates:-

1. Clove Plant

Clover plants do have a vanilla scent that repels rats. Simply pick the leaves of the clover plants, soak them overnight, and sprinkle the water on areas where you feel there is an infestation of rats. Within no time, the rats will smell the clover plants’ scents and flee.

2. Garlic

It is true that garlic has a distinctive and strong smell that deters rats. It works well to use garlic and onion. Simply chop them into small pieces and boil them for two to five minutes. Then, pour the boiling water into a spray bottle.

Place the water around places where rats typically roam and where you see droppings and footpaths used by rats.

3. White Vinegar

White vinegar has a very strong and unpleasant odor, particularly to rodents such as rats. This will undoubtedly drive them away. Spraying around where they nest is the most effective method. Rats will be scared away by a strange odor.
