It is sometimes possible to use borax as an insecticide, to eliminate cockroaches and insects. Borax is a chemical product in the form of a white powder, whose components are boron, sodium and oxygen. Borax is used in many fields in the household, especially in cleaning, odour removal, and is also widely used for soldering silver.
Why is borax valid as an insecticide?
Borax as such is not the best insecticide. But if you already have borax at home, or if you want to buy it to use it for cleaning, deodorising, etc., it can also be used as an insecticide. If you mix borax with lemon juice (or citric acid), you will create a new compound which is boric acid. The chemical formula of boric acid is H3BO3 and of borax is Na2B4O7-10H2O. The boric acid is one of the most effective products against cockroaches and ants.
Both borax and boric acid look the same, in the form of a white powder, and are often confused. They are not the same product.
How to use borax to get rid of cockroaches and ants
As mentioned in the previous section, borax by itself is not an insecticide, but if we mix it with citric acid, the borax particles will decompose into boric acid, which is a well-known product for eliminating cockroaches and ants.
The first thing to do is to create a paste with borax and lemon juice (1 glass of borax with 1/4 of lemon juice).
Subsequently, you have several methods to apply this paste to vulnerable areas of your home where cockroaches and ants may appear. Given that by adding lemon what we have achieved is to convert the borax into boric acid (at least part of it), here are several ways to apply it and eliminate the dreaded insects in your home: how to get rid of cockroaches and ants
