Where do roaches come from in the bathroom?

Roaches are not dangerous pests. They cannot bite a human being, but they carry many bacteria that affect them. Bugs can damage your clothes, pillows, and other soft things. They can infest your kitchen and bathrooms and even get into any room of your house. Knowing how they enter bathrooms, kitchens, or any room is essential, despite killing or catching them. Therefore, it is better to stop them instead of killing them.

Cockroaches get access to restrooms by climbing up drains, squeezing through leaking pipes, locating cracks in baseboards, slipping under doors, and crawling through tiny holes in walls or ceilings. Cockroaches occasionally enter the house in many ways and move to the bathroom because of wetness and humidity.

Why are there roaches in the bathroom?

Knowing what cockroaches in your home find alluring will enable you to take prompt action to eliminate those attractions and completely prevent an infestation, saving you from using potentially harmful chemicals to treat the issue severely.

Cockroaches’ primary motivation for entering domestic homes is their need for shelter, food, and water. Let’s take a deeper look at each of the three and other attractions:


Due to their omnivorous nature, American cockroaches will happily consume practically everything they can find inside your home. It includes breadcrumbs, pizza crusts, toothpaste, glue, soap, and animal excrement. Given this, not only may your kitchen and cabinets serve as a fantastic shopping area for these annoying bugs, but also your bathroom and, in theory, any other room in your home.


Roaches cannot go more than seven days without drinking. However, they can go long periods without eating quite fine. Therefore, your house won’t attract cockroaches, clean or unclean, until there is water. The kitchen, the basement, or the bathroom may be more roach-friendly than other rooms in the house because of the easy availability of water there. However, this does not imply that the tiny ghouls won’t want to explore other areas of your home. Mainly as their population grows and the pressure from the competition forces them to seek new food and water supplies.

Hiding places

Roaches may enter your home to procreate, which is another reason they would do so. Therefore, they choose locations that are difficult for people to access, heated, humid, and poorly ventilated. The most common cockroach hideouts are kitchen cabinets, the area under your refrigerator or around your sink, floor drains, and water heaters.


Windows are open, and lights are on in most of the house. Bathrooms, on the other hand, are usually gloomy. Roaches are left alone and unbothered when there is less human activity. They prefer it just like that. As you can see, restrooms are cockroaches’ ideal habitat. They will do so if they can nestle into this area. You can then be left wondering how they got inside.


Your shower will produce a steamy, warm environment on a semi-regular basis. Warm conditions are ideal for cockroaches. The bathroom is the best spot to dwell if the rest of your house is chilly.

How to prevent roaches from getting into the bathroom?

Knowing how cockroaches enter your bathroom will enable you to deal with the issue at its early stages and stop the entrance before a full-fledged infestation starts. The faucet on the sink, for instance, has a cockroach sitting on it. Ideally, you should be aware of the biology, behavioral tendencies, and preferences of the particular species invading your house to choose the most effective method of controlling unpleasant bugs. It would be a nuisance to catch one and transport it to an entomologist, so don’t do that.

You can get by with the universal advice listed below, barring a severe invasion. Their purpose is to prevent roaches from accessing food and water sources and prevent them from finding shelter inside your walls.

Remove food source

Roaches may find great nourishment in various places, including soap bars made of starch, skin care items, toilet paper, rubbish, and even a brush with your hair. Store any organic washroom products in firmly closed containers.

Modify your bathroom sinks

The only reason roaches cannot enter through modern toilets is because of the water traps that prevent water, odors, and insects from entering the sewer. You can install A P, J, U, or S-bent water traps on your bathroom sink to keep cockroaches away and lessen the likelihood of clogging.


Roaches will perish from insecticides. The majority of brands, however, are made to fumigate homes or to be sprayed on pests. Pouring it down the drain cannot work or have adverse effects. That is a result of pesticides’ high toxicity. Not just roaches will get harmed if you pour an entire can into the drain. Other organic stuff nearby will suffer harm. It can seep into the ground, adjacent water sources, your sewer system, and other areas. According to the Journal of Economic Entomology, numerous studies have shown that pesticides can linger in the soil for up to three years. In certain places, flushing pesticides down-pipes can even be prohibited.

Boiling water

Use boiling water if cockroaches crawl up your bathroom drain. It will not harm your pipes, unlike bleach or pesticides. Hot water won’t seep into the soil or water either. You can kill roaches using bleach or water that has reached a rolling boil. But this approach comes with a few limitations. First, boiling water is only helpful for a short period. Especially in colder months, it may rapidly become chilly when poured down a drain. The water could not be hot enough when it reached roaches at the drain’s bottom.


Do roaches emerge from shower drains?

Because cockroaches can fit through even the most minor gaps, drains and pipes directly connected to the sewage serve as great access sites for them into your shower or bath drain, kitchen and bathroom sink, and even toilet.

Do cockroaches originate in sewers?

Yes, roaches are invasive, opportunistic pests that choose the sewage system as their preferred habitat. Cockroaches from the sewage system may so find their way into your home.

Can a roach survive being flushed down the toilet?

Since cockroaches can hold their breath for up to 40 minutes, flushing them will not kill them. It will be alive when it enters your sewage. It can then find its way back into your house or a neighbor’s home in that condition.

How long does it take for a roach to drown?

A cockroach can maintain its air supply for 40 minutes and tolerate total immersion for 30 minutes. Furthermore, they frequently have their breath because they must control their water loss, making them excellent at it.
