Two other ingredients that repel these insects are undoubtedly sugar and baking soda. You can dissolve and mix these two ingredients in water to create a pasty mixture, which you can always place at strategic spots outside the house.
Cockroaches are attracted to sugar, but baking soda kills them instantly, as it is toxic to them.
We conclude with another completely natural solution. It’s possible to spray a mixture of water and Marseille soap near doors and windows. The smell repels cockroaches, and you will no longer have such insects in your house.
