What is Boric Acid?

Boric acid goes by several names, such as acidum boricum, hydrogen borate, boracic acid, and orthoboric acid. It is a weak monobasic Lewis acid of boron, In simpler terms, boric acid is a compound made up of boron, oxygen, and hydrogen.

You might be wondering where boric acid comes from. Well, it occurs naturally and can be found in certain minerals and volcanic areas. However, commercially, it is often produced by reacting borax with hydrochloric acid.

Boric acid can take the form of colorless crystals or a white powder that dissolves easily in water. It doesn’t have any strong odor, so you won’t be overwhelmed by unpleasant smells when using it.

One interesting thing about boric acid is its versatility. It possesses antiviral, antifungal, and antiseptic properties, which makes it useful in various applications. Apart from mice control, you can find boric acid in products like antiseptics, insecticides, flame retardants, neutron absorbers, and as a precursor to other boron compounds.

It’s worth noting that boric acid is a weak acid, meaning it doesn’t fully dissociate in water. Its pH value, a measure of acidity, is around 9.24, making it mildly acidic.

How Does Boric Acid Work in Pest Control

Boric acid is a common ingredient in many insecticides and is often used to control pests like cockroaches, ants, and bed bugs.

Here are a few ways in which boric acid works in pest control:

• Boric acid can kill insects if they eat it. When insects ingest boric acid, it can disrupt their stomach and affect their nervous system. It can also scratch and dehydrate their exoskeleton, which can ultimately lead to their death.

• Boric acid is most commonly used in pesticides and can be found in a variety of forms, including tablets, liquids, powders, and traps.

• Applying boric acid topically or by contact with the insect is not effective. Insects must eat the boric acid for it to be effective.

• Boric acid is a slow-acting poison, which means that it can take several days to kill an insect. This slow action can be an advantage in some cases, as it allows the insect to carry the poison back to its nest or colony, where it can infect other insects.

However, it's important to note that boric acid may not be effective against all types of insects, and its efficacy can vary depending on the species and circumstances.

While it can be successful in combating certain pests, it may not always be the best solution for every situation.

What is the Difference Between Boric Acid and Borax?

Before we discuss how to use boric acid for mice control, it’s important to understand the difference between boric acid and borax. While both compounds contain boron, oxygen, and hydrogen, they have different chemical structures and properties.

Unfortunately, many people mistakenly use these terms interchangeably, which can lead to confusion and potentially unsafe practices. So here, we’ll explain the main differences between boric acid and borax.

Boric Acid

• Chemical formula: H3BO3.

• Also known as hydrogen borate, boracic acid, and orthoboric acid.

• Weak monobasic Lewis acid of boron.

• Weak acid with antiviral, antifungal, and antiseptic properties.

• Used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other boron compounds.

• Prepared by reacting borax with mineral acid or hydrochloric acid.

• Soluble in water and does not have any characteristic odor.

• Usually encountered as colorless crystals or a white powder that dissolves in water.

Borax

• Chemical formula: Na2B4O7·10H2O
