They say it is the only animal that would survive a nuclear disaster. We can hardly ever confirm this, but we can be sure that cockroaches is a large and persistent problem for most homes, especially in cities.
However, there are some simple and completely natural ways to get rid of cockroaches at home, without resorting to the use of chemicals which are harmful to your health.
Natural ways to get rid of cockroaches.
1. Boric acid: It is a common homemade bait to kill cockroaches. Mix one part of boric acid powder with a portion of white flour and one part sugar. Mix thoroughly to make a paste that looks like dough. Place small balls of the dough in various parts of the house where you have noticed cockroach presence. The flour and sugar in the mix will attract cockroaches and the boric acid will kill them.
You can also make a similar bait using 1 part of boric acid, 1 part cocoa and 2 parts white flour.
Continue to use the bait for at least two weeks to ensure that all the cockroaches are gone.
CAUTION: Keep this mixture away from children and pets, as this is quite toxic.
2. Sugar and baking soda: You can make a mixture of equal parts of baking soda and sugar and “sprinkle” it near the points you have noticed that there are cockroaches in your home. Those fed with this mixture die, because baking soda reacts with the acid in the stomach and makes them “burst”.
3. Soap solution: You can use regular bath soap to get rid of cockroaches. Prepare a mixture of soap and water and spray it directly on them. Most will die immediately, because the solution closes the pores which they use to breathe.
4. Bay leaves: The bay leaves are aromatic leaves used primarily in Indian cuisine. They have a spicy but nice fragrance. You can place crushed powder (dried) bay leaves near the nest and in other areas where cockroaches visit. The smell will make cockroaches spots and cockroaches would prefer to leave your home, without having to kill them.
5. Ammonia solution: Add two cups of ammonia in a bucket full of water and rinse with this solution in your kitchen sink and all what gutters home. The smell of ammonia will keep cockroaches away. Repeat this “trick” once a week.
6. Pepper, garlic and onion: Make a mixture of one tablespoon of cayenne pepper powder, one clove of garlic and a crushed onion in a liter of water. Allow to stand for one hour. Add one tablespoon of liquid soap in this mixture and apply to all areas in your home where cockroaches frequented. The smell of the mixture will make them flee.
7. Cucumber: Take a box of aluminum and place some cucumber peels or pieces within it. Leave overnight. The juices of the cucumber react with the aluminum box and produce a smell that cockroaches can not afford.
