3 Best Natural Home Remedies To Kill Cockroaches Fast & Permanently

Cockroaches are one of the common household pests found all over the world, they feed on food remains and can cause a bad odor. It is not only the bad smell that is bad about cockroaches, they transport microbes and can cause severe allergies.

Especially people with asthma should be careful of cockroaches as they trigger allergic reactions in most asthma patients. Cockroaches can become a huge problem because of two reasons, one they multiply so fast and second they can last so many days without food.

Also many of you may not be aware that if cockroaches multiply too much there is a risk of cockroach bite too. When I was in hostel my friend was bitten by a cockroach and she developed serious allergies. Kitchen is the most common place that cockroaches are usually found. Traditionally in India, we had open shelves in the kitchen which is fast being replaced with closed shelves now.

Closed shelves are not a problem if you wipe the vessels and place them inside. But if you keep wet vessels inside the shelves, there are great chances for cockroach infestation as cockroaches love damp and dark places. Once cockroaches are inside closed shelves, it starts smelling real bad. Also cockroaches are very very good at hiding so it is hard to find them to kill.

I would suggest not using cockroach sprays available in the markets as no matter how careful you are, some will be sprayed on the vessels too. Instead try the cockroach repellent spray given below, it is a safe way to get rid of cockroaches.

If you don’t have kids around the house, you can try the cockroach repellent balls, cockroaches get attracted to the sugar in it and when they eat them they die. But I would suggest not using it if you have young kids around as it has borax which is not safe for internal consumption.

The next remedy is diatomaceous earth, when sprinkled on the surface where cockroaches are commonly found, it sticks to their feet, enters their body and kills them. Once there is cockroach infestation, try any of these remedies to get rid of them and then you can wash or wipe down the whole place with neem water (neem leaves boiled in water) and let it dry completely before using again….

3 Natural Home Remedies For Getting Rid Of Cockroach: 

1. Cockroach Repellent Balls Recipe:


Take borax, flour and sugar in a bowl. Add enough water to form a thick mixture. Now make small balls out of it and keep it in places where cockroaches are usually found in kitchens and apartments. Borax kills cockroaches and flour and sugar in the recipe attracts them. This is a safe method but if you have kids or pets at home, try the second remedy as it is toxic if borax is consumed internally.

2. Cockroach Repellent Spray Recipe:


Take sweet flag root and pound it to break into small pieces. Add neem leaves and pound to crush the leaves too. Now take the crushed herbs along with water and boil for till the water is reduced to 1 cup. Switch off, cool, strain and take in a spray bottle. Use this cockroach repellent spray in places where cockroaches are normally found.

3. Diatomaceous Powder:

Sprinkle diatomaceous powder on the places where cockroaches are commonly found. If you are wondering what is diatomaceous powder, it is a fine powder got from crumbling a type of natural rock that contains fossil remains of an algae called diatoms.

This is a very very safe way to kill cockroaches at home because it is very very safe for humans and pets. Diatomaceous powder does not have any chemical that magically kills cockroaches but the particles are small and sharp and when cockroaches walk on them it sticks to their bodies.

Then it cuts into the exoskeleton and absorbs the water and cockroaches die of dehydration within 24 to 48 hours. You can order diatomaceous earth online and when buying look out for food grade quality……

      I understand, I wanted to give all the options available so one can choose the ones that they prefer to eradicate cockroaches without using harmful chemicals. If you don't want to kill and just want to drive them away, you can use the neem repellent spray given above. At home, washing our whole kitchen monthly once along with spraying with neem water greatly prevents cockroach infestation…

      Some chemical stores stock borax in India and if you have difficulty finding it, order it online through shops like amazon.in….
