Cockroach in Bathroom: Why They’re There & Prevention Tips

1. How to Prevent Cockroaches in the Bathroom? 

Cockroaches are drawn to environments with high humidity and moisture, making it crucial to maintain a clean and dry bathroom to deter their presence. Follow these tips to prevent cockroaches in the bathroom:

  1. Keep the bathroom clean: Regularly cleaning the bathroom helps eliminate damp spots, mildew, and shed skin cells that attract and sustain cockroaches. A consistently clean environment discourages roaches from establishing a habitat.

  2. Seal cracks and crevices: Prevent cockroaches from entering your bathroom by sealing small openings with caulk or weather stripping. This limits their access points.

  3. Install water traps: Water traps in sink drains can prevent blockages and discourage roaches from entering, as they are attracted to moisture.

  4. Repair leaky pipes: Cockroaches are enticed by moisture, so fixing any leaky pipes is crucial to prevent them from entering and thriving in your bathroom.

  5. Store food properly: Properly store food to eliminate attractants for cockroaches, reducing the likelihood of their presence in the bathroom.

2. Why Are Roaches Coming Into Your Bathroom? 

Bathrooms attract roaches more than most people know. This room provides all the conditions they need to survive and stay well-fed. Some of these conditions include: 

1. Moisture

Bathrooms are water havens for insects that love to drink this life-giving liquid. Roaches can be found drinking water from sinks, toilets, and shower drains.

Wiping down surfaces daily with a microfiber towel is crucial to eliminate moisture sources.

2. Sufficient Hiding Places 

Cockroaches live in a constant state of high stress due to predators and humans trying to eliminate them.

Finding spots to conceal themselves is a matter of survival. Bathrooms offer a sense of safety with hiding places like: 

  • Garbage bins 
  • Behind the toilet 
  • Bathroom cabinets 
  • Surrounding shower areas 
  • Under the tub 
  • Cabinets 

Roaches’ flexible exoskeletons allow them to squeeze through tiny holes, sometimes as small as 1/6th of their body width.

3. Warmth 

A relaxing hot shower with steam is a human luxury, but it creates an environment that attracts roaches, as they thrive in warm and humid conditions.

A warm bathroom becomes even more inviting when other areas of the home are colder. 

4. Possibility of Finding Food 

Unusual as it may seem, cockroaches do find some food sources in bathrooms due to limited options.

Some of these sources include toothpaste residue, soap bars, flavored skin care creams, toilet tissue, used tampons, ear cotton swabs, and other female hygiene products. 

5. Darkness

Bathrooms and closets are typically the least lit areas in a home. Roaches take advantage of the lack of light and the reduced human traffic in these areas.

Bathrooms become perfect places for roach infestations to flourish, especially under drain pipes and in discreet corners.

3. How Did a Cockroach Get in My Bathroom? 

If you find cockroach in bathroom, start by investigating these potential access points: 

1. Pipes 

Drains and pipes provide damp passageways for roaches to access your home from sewer systems.

As pipes age and develop cracks, they become entry points for roaches from the outside. Address cracks promptly to prevent a worsening roach problem. 

2. Cracks and Crevices in Your Walls 

As houses age, they develop holes and cracks on their exterior walls. These imperfections create hiding spots for roaches.

Even the smallest holes can provide entry for roaches, with some research showing that even giant German Cockroaches can fit through holes as small as 3mm. 

3. Baseboards and Tiles 

Pay attention to the baseboards and tiles in your bathroom. Even minor holes in tiles can provide entry points for roaches.

Wooden baseboards can also chip and crack with moisture exposure, giving roaches an opportunity to enter.

4. Spaces Under Doors 

Roaches often travel through homes by using gaps under doors. If your kitchen is well-sealed and clean, roaches might venture into your bathroom using this method.

Whether your bathroom door is open or closed, roaches can find their way in through gaps under the door.

4. I Saw One Cockroach, Should I Be Worried? 

Spotting a single cockroach should not be taken lightly. Often, one roach sighting indicates the presence of several more hiding nearby. However, assuming that the infestation is limited to your bathroom could be a mistake.

While bathrooms are attractive to roaches due to their moisture and hiding spots, other areas of your home can also become infested. 

If you think the roach issue is contained to your bathroom, you might focus solely on that area. Unfortunately, this approach might allow other infestation points to flourish unnoticed. 

Acting promptly is crucial. There’s still an opportunity to eradicate these pests before the problem escalates into a full-blown infestation. 


In the battle against cockroach in bathroom, knowledge is your most powerful weapon. By understanding the reasons behind their invasion, their habits, and effective prevention strategies, you’re well-equipped to reclaim your bathroom sanctuary.
