What Attracts Roaches To Your Drain?

Roaches just like us are constantly looking for a good and healthy environment to live in. Two things attract them to your drain, a place to stay and nest and also the moisture in your drain.

Roaches love a wet environment and cannot live for more than 4 days without water, so they are always looking for the best place with enough water to stay. 

Your drain provides them with this steady supply of moisture they need to survive. If there is anything they can eat around the drain too, they will feed on it but they are more concerned about getting water to drink and stay alive. 


What Cockroach Species Can Be Found in Drains? 

The species of cockroach you will find in and around your drain are the oriental cockroach, American, and brown-banded cockroach. Oriental cockroaches commonly called water bugs because of their love for water are attracted to the organic matter that gathers in drains and pipes.

American cockroaches mostly live outdoors but during the day, you can see them close to your outside drain system especially if the pipes are leaking.

You can also see brown-banded cockroaches under your kitchen sink and in your bathrooms because they prefer to live indoors in the home. Although they mostly stay in the warm area of the home, they will go to sinks and drains to find water.

How Do Cockroaches Into The House?

There are many ways a cockroach can get into your house and your drain area. If you live in a building that has connected drain pipes, roaches will enter your house through these pipes.

You can also, unexpectedly carry roaches into your house from outdoors without knowing. If you were in the garden, out for a picnic, or just anywhere where roaches were, you could take them back into your house with you.

Let’s not forget that they are very flexible so any little crack in your house wall can serve as an entry point for them. 


How to Kill Cockroaches in Drains

There are many methods you can use to get rid of roaches inside and around drains and sinks. Here are a few that work for me:

  1. Get rid of any trash around the drain and sink. To get rid of these cockroaches, you have to start by getting rid of any food particles, dirt, or any matter that cockroaches can eat around your sink and drain. Now that we have gotten rid of the dirt around the pipe area. Let’s look at the methods to kill cockroaches in drains.


Method 1 

Boiling water:

Get a pot and boil some water. Boil over 2 liters of water so you are sure it will flush out the drains well. Once the water is boiling, pour it into the drain. I pour chill water down the drain a minute after pouring the hot water. I do this because I don’t want to damage my pipes.

The hot water in the pipe will get cold almost immediately, but I still pour in cold water just to be on the safe side. This method may not work at once. you will have to repeat it more than once to get the entire infestation. 


Method 2


Bleach is very good at killing roaches because of the chemicals in it. Pour 3 capfuls of bleach into the drain. Sometimes I put the bleach in hot water to pour it.

The downside of using bleach is you may not be able to tolerate its smell. If you have children or any breathing problems, please do not use this method.

Something you can do is when you want to use the bleach. Take your children outside to play or stay outside. Let the chemicals in the bleach work their magic, while you are having the time of your life. Then return to your roaches-free house. 


Method 3

Using pesticides:

There are several roach pesticides available that you can get here on Amazon. Get one of these and use it according to the manufacturer’s instructions. 


Method 4

Baking soda and vinegar

What you will need; Vinegar and Baking soda. Pour the same amount of baking soda and vinegar into a bowl. Then pour your mixture inside the drain. Not only will this method work. But vinegar will kill the germs sprayed by the roaches. Remember to wear your gloves before doing this.

Final Thought

You have done It! You have successfully gotten rid of the roaches in your drain. Well done. Remember roaches are a pest and should not be allowed to breed.

If one method is not working, use two or all of the methods I mentioned above.  For example, you can use boiling water, followed by baking soda and vinegar solution or pesticides.
