Water sources attract roaches.

Bathrooms are moist from the shower drain, toilet, or leaky faucets. Cockroaches will quench thirst from all these water sources.

Excellent Hiding Places

Cockroaches acknowledge that they are prey insects. When larger animals are nearby, they try to fit themselves into hiding places. Bathrooms provide myriad safe spots, and you can find cockroaches like:

  • Bathroom Closets

  • Behind toilets

  • Container of garbage

  • Racks and products displayed on shelves

  • Shower drain pipes

  • Washroom exhaust fan

  • Under the jacuzzi

A roach can live in even the smallest of holes. Several other species could even fit into holes one-sixth of their body structure.



Have you wondered? On a moderate basis, your bathroom shower will end up creating a balmy, warm place. Warm environments attract roaches. If the remaining part of the house is cooler, the Bathroom will appear to be a perfect place to live.

Possibly Human Food

Bathrooms, although less ideal than kitchens, include more options for food sources. These consist of:

  • ToothpasteSoap

  • Toilet tissue

  • Skincare products may contain chocolate, cream, or dirt

  • Materials used for sanitization, such as ear swabs and feminine hygiene products.



 Most doors are opened, and the lights are switched on but

on the other hand, bathrooms are normally dark at night.

Roaches are left all alone unhindered when there is no result of human activities. That’s how they prefer nighttime.

As you can see, the bath area is a cockroach’s haven to hide.

Can you imagine? They will nestle themself into this safe area if they have the chance. That may make you question how they ended up getting in.

Points where Roaches Enter Bathrooms

There are multiple ways for roaches to enter the bathrooms, many of which are noticeable to humans. Check out the following entry points if you discover bugs in your Bathroom:



Roaches frequently enter homes via plumbing and drain. Pipes that are destroyed, leakages, or cracks can provide unprotected entry on both the inside and outside. What seems to be a slight nick in your sewer systems could be fair game for these pests.

Pipes inside include a pathway for cockroaches. These pests can go through the rest of the house and control the other water leakage to gain entry. Roaches will enter your drains because the Bathroom is where most of your plumbing occurs.

Have you noticed? Cracks in pipes may turn into an even bigger problem in housing units. The shared walls enable an infestation by one house to be quickly transmitted to other parts. Pipes will help cockroaches by acting as routes to new hideaways.

Holes or Cracks and Crevices in the Wall Surfaces

It is usual for cracks or holes to form on the outer walls of homes as they age. Narrow crevices may create in the trimming, base skirt, wall panels, or edges. If they become too extreme, they can end up causing leakages and structural damage.

You might be wondering how a cockroach, on the other hand, only requires a small gap to gain entry into your Bathroom.

Baseboards and Tiles

Baseboards and Tiles

A cockroach can fit through the tiny holes in the foundation. Tiling enables this process even though small cracks will not destroy the entire square but will leave a gap. Those frayed edges may also be used as a hidden room for roaches.

Bathroom Doors with Gaps

I’m not too fond of it when suddenly I see cockroaches in bathroom door gaps. By the way, a cockroach might also enter the home from another location entirely. The shower drain and sinks will be enticing to roaches.

A cockroach may use holes under the doorway to intrude. Cracks underneath the door seal may also increase the likelihood of roaches gaining access to the bath.

How To Prevent Roaches away from the Bathrooms?

If you’re using a soap bar, keep it in a sealed box. You can also use shower gel instead.

Toilet papers 

Toilet papers

Moreover, must store toilet rolls inside their container. It must preferably be kept in the packet it came in till you need it.

Roaches are drawn to paper, particularly toilet tissue paper. Toilet rolls serve not only as a food source for roaches but can also disperse germs on them.

A water trap is needed in all modern restrooms. They can also be implanted in other sinks. Roaches are effectively deterred by P, J, U, and S water hooks. Furthermore, installing such traps can aid you in avoiding the blockage in pipes.

When dealing with leaking pipes, ensure the repair is perfect and long-lasting. Although during winter weather, partly fixed drains sink or pipes will crack. Cold weather is also a good time for cockroaches to look for a new warm home.

Roaches can be drawn to any item that retains humidity in your shower room. Consider the following to keep moisture at bay:

  • Including a dehumidifier

  • Placing in a Bathroom Fan

  • It will make it less alluring to cockroaches and help prevent mold.

A bathroom mat is yet another major source of water content. It shouldn’t be left soggy on the floor, particularly if it is heavy or shaggy. After using it, always hold it up to air-dry so that moisture does not gather in it.
