Five Possible Reasons Why You Hear Scratching Under The Bathtub

The mysterious scratching noise coming from underneath your bathtub can be a cause for concern.

Apart from causing discomfort to your ears, it is also a cause of great concern as far as the safety of your property is concerned.

There are a few possible explanations for the noise, including animals or insects getting into the space under the tub or pipes rubbing against each other.

An animal is likely the culprit if you hear a scratching at night. This could be a mouse, rat, or even a tiny squirrel.

If you hear the noise during the day, it’s probably just a branch or something rubbing against your house.

Either way, it’s best to investigate the noise to be sure.

Here are five reasons that could be causing the irritating scratching:

1. Presence of Rodents

If you’re hearing a scratching noise coming from underneath your bathtub, it’s probably due to rodents.

Mice and rats are known to squeeze into small spaces, and your bathtub’s drain pipe is a perfect size.

These pests can cause severe damage to your home, so getting rid of them as soon as possible is essential.

There are a few different ways to do this, such as setting traps or hiring a professional exterminator.

So, as soon as you notice any sign of them, act quickly to rid them of the property before they cause more destruction in the home.

2. Pipes Rubbing Against Each Other

If the pipes underneath the tub begin to lose due to aging and other factors, they can start rubbing against each other and cause the scratching noise.

Such lines usually pose severe ramifications as they can break any minute and cause serious water leakage.

You must take swift action and call your plumber to rectify the issue before things get out of hand.

3. Insects in The Space

Like rodents, small insects can find their way into the bathtub and cause a scratching noise.

Vacuuming the bathtub can help remove them. You can also use an exterminator, as we will discuss later in this article.

4. Expansion and Contraction of the Pipes

Another possibility is that the noise comes from your plumbing pipes as they expand and contract due to temperature changes.

If the scratching only happens when you turn on the water, the noise is likely coming from your pipes.

If you need help determining what’s causing the noise, you can always call a professional to come and take a look.

5. There Could Be Something Dropped In The Drain

Another possibility is that something has been dropped down the drain and is now stuck.

If a dripping sound accompanies the scratching, it may be caused by a leaky pipe.

How Can You Get Rid Of The Scratching Noise In The Bathtub?

There are a few ways to eliminate the noise, including sealing up any openings that could let the noise in.

You could also try to soundproof the room, or if you have extra space, you could move the bathtub there.

Here are four ways to deal with the problem of scratching in the bathtub:

1. Seal All Open Holes And Entryways

You should first try to seal up any holes or cracks that they could be using to get into your bathroom.

You can also try setting out traps or bait to catch the pests.

If that fails, hire a professional exterminator.

2. Fix The Problem Yourself

If you can fix the problem yourself, first try to identify what is causing the noise.

It could just be a loose pipe or drain cover. If you can identify the problem, tighten any loose screws or caps and see if that fixes the issue.

3. Contact A Plumber

This is one of the most effective methods of dealing with the scratching sound in your bathtub.

If it is broken or lost pipes, a plumber will bring in the expertise required to repair and connect lines in some of the most intricate points, like the bathtub.

Even though you will have to pay for these services, calling a plumber is the best thing you can do. Your problem can be addressed decisively.

Three Bathtub Problem Preventative Tips

1. Regularly Clean Your Bathtub

Ensure you regularly clean the area around your tub, including the drain. This will remove any build-up of soap or other materials that could be causing the scratching noise.

2. Do Not Use Strong Chemicals In the Bathtub

You should avoid using harsh chemicals or abrasive cleaners on your tub, as these can damage the finish and cause the scratching noise to become worse.

3. Identify The Cause Early and Try and Solve It

If you hear the scratching noise, try to identify the source and take steps to prevent it from happening again. We already discussed how you could do that.

Final Words

The most likely explanation for the scratching noise you hear coming from underneath your bathtub is that rodents cause it.

Mice and rats are attracted to the warm, moist environment under a bathtub and will often build nests there.

The scratching noise is likely caused by the rats or mice running around and moving their nesting materials.
