How to Get Rid of Oriental Roaches

If the cockroaches have already invaded your house, then there are certain measures you can take to control and get rid of them naturally.

Here are a couple of the most effective ones:

Remove Their Food Source

Just like humans, cockroaches need food to survive; but unlike humans, they can live off on anything from decaying food to crumbs and even debris.

One of the most successful ways to get rid of Oriental cockroaches in the house is to deny them food and water.

You can start by cleaning the crumbs or any left-out food.

Don’t keep dirty dishes piled up in the sink; this is like a treat for them.

Tightly pack and seal all your food containers, cereal boxes, milk cartons, etc.

Keep your common kitchen appliances clean and dry like the back of the refrigerators, toasters, oven, etc.

You have to remember that this isn’t a one-time solution; you need to keep taking these steps regularly to make sure you are not creating a hospitable place for them.

Eliminate Moisture

Did you know that Oriental cockroaches are also called as ‘water bugs’?

This is no secret that cockroaches like damp places with enough moisture and which is hidden from the human eye.

If there is a cockroach in your house, it means there is a place for them to hide as well.

And although cockroaches can live without food for weeks, they do need water to survive.

So another major and necessary step you need to get rid of these oriental roaches is to remove any moisture in your house.

Some of the most common places to look out for are any leaky pipes or open drains that need to be fixed.

Also immediately get rid of any standing water like leakage behind refrigerators or excess water in potted plants or sinks and drains

Eliminating moisture is one of the most important steps you need to take to keep your house protected from these pests.

Stop Their Entry

Although it may sound like a no-brainer, you would be surprised by how many people ignore to take care of this.

Cockroaches can scuttle their way inside your house through the smallest crack and holes.

So you need to make sure not to allow them to get into the house in the first place.

Seal all the cracks and crevices in your foundation wall, your bedroom, especially your kitchens and bathrooms.

If you have a basement, you need to pay more attention to making it impenetrable since they provide the perfect refuge for them- a dark and warm place for dwelling.

Check your house thoroughly and fix any holes or cavity you see like inside your pantry or in the baseboards etc.

 These pests can squeeze their way through the smallest opening so you need to make sure you leave no stone unturned.

Best Cockroach Killers for Oriental Roaches

Now, sometimes despite using all the home remedies (which we will discuss after this) and organic solutions, these roaches still don’t leave.

And this is especially true if you are dealing with an infestation.

In such situations, we have got you covered.

Here are some of the most recommended Oriental cockroach killers which are not only hassle-free but are also easily available online.

Cockroach Traps

Cockroach traps are one of the most commonly used products among homeowners due to its easy application and desired results.

Cockroach traps are devices that usually have bait or some type of attraction for the roaches to lure them on it.

Once they step on it, they get stuck and become immobile due to the adhesive applied on the trap.

This is a very efficient solution that helps you to get rid of them without using any major chemicals in your house.

These gel baits contain a variety of formulation of lethal insecticides like chemicals that kills these pests easily.

The most basic way to use them is to apply small dots of this gel in cracks and gaps of the common hiding places of these cockroaches.

They attract the pests, who get lured thinking of it as food, and consume it, thus killing them.

Cockroach Fogger

In recent years, cockroach foggers, also known as ‘cockroach bombs’ have gained a lot of popularity as an effective alternative for killing and getting rid of these roaches.

The idea behind this is that these foggers create a pest control like effect by releasing a mist of insecticide in the air.

It has proved to be a good solution to deal with infestations.

However, they do have a lot of chemicals and can be toxic for children or pets if inhaled directly. 

Hence, this should only be used in case of a serious infestation and under the guidance of a professional exterminator.

How to Kill Oriental Roaches with Home Remedies

Many times, when you are not facing a serious infestation and you don’t want to use chemicals in your house, you look for alternative solutions that provide equally fruitfuloutcomes.

And, what is a better alternative to chemicals than home remedies?

However, not all home remedies work so you need to choose carefully.

Below mentioned are some of the tried and tested ones which have given the desired results.

Boric Acid Bait

If you do not wish to use a chemical bait, you can always make your own 100% natural cockroach bait by using boric acid.

Boric acid is a very common home remedy because they are extremely toxic for cockroaches but relatively harmless for humans and pets.

To create your bait, all you have to do is mix boric acid and powdered sugar and sprinkle it in all the places where you think these roaches hide.

The sugar will lure them and the boric acid will kill them.

Sprinkle it behind the stove, refrigerators, in cracks and crevices, etc.

Diatomaceous Earth

Food grade diatomaceous earth is another excellent homemade alternative that can be used to get rid of the cockroaches.

Diatomaceous earth is non-toxic and harmless for humans and pets but kills these pests by breaking down their exoskeleton.

All you have to do is sprinkle this powder in the common entry points and hiding places of these cockroaches.

It works incredibly well and is cheap and easily available.


Borax is a salt of boric acid and is equally effective in getting rid of the roaches for you.

They work similarly, however, just like boric acid; borax also needs to be mixed with a bait (powdered sugar) to lure the cockroaches.

Once ingested, they kill the pest quite smoothly.

Sometimes, the cockroaches even carry the ‘baits’ back to their hiding places, thus killing other cockroaches that eat it.

Also, since borax is a common laundry cleaner, it can be easily found in a supermarket or a grocery store in the laundry aisle.


Bleach is one of the most generic DIY remedies adopted by people who face this problem of the Oriental cockroach invasion.

They have proved their effectiveness time and again through years and hence are still reliable and preferred when it comes to home treatments.

Once the cockroach comes in contact with the bleach, they are sure to die immediately.

However, bleach is a cleaning agent and has a very strong smell which cockroaches detest.

This smells makes them scurry away, making the contact difficult.

Other roach baits attract the cockroaches but bleach doesn’t offer that.

So although it is very effective, you need to use it in a way that makes the contact with the pest possible (maybe through drowning or ingestion, etc.)
