How to Use Boric Acid for Bed Bugs

Here’s how to use:

  • Place boric acid powder around the legs of your bed. If the bed bugs go through the powder while in the process of finding a host to feed, of course they won’t die but some will die days after exposure.
  • You can also make a liquid borax acid solution. This is convenient and easier to apply then boric acid. The trick here is to spray the mattress and the carpet heavily with boric acid. In addition, spray your beddings and carpet with warm water. The goal here is to suffocate the bed bugs such that after inhaling it, some are likely to end up dead. Make sure thereafter to vacuum the surfaces sprayed on with boric acid to get rid of either dead bed bugs or unconscious ones.
  • Apply the liquid borax acid on other furniture where you highly suspect there is an infestation of bed bugs. Try spraying the acid in and around the areas and give it time. After a while, use a steam cleaner or just an ordinary vacuum cleaner.

Boric Acid and Borax – Differences?

Boric acid and borax – is there any difference? In this section, let’s briefly discuss the differences between these two.

The difference between boric acid and borax can be described from the very beginning. The process of production is what separates the two. While borax is mined from the ground, boric acid come directly from borax.

To come up with boric acid, you have to put borax into boiling water and hydrochloric acid. Once the mixture cools down, then start the process of boric acid crystallization.

The process involves filtering boric acid crystals. The purity level can be adjusted depending on one’s need.

Two, while borax is mined from the ground, boric acid on the other hand is in the powder form. Boric acid doesn’t get a chance to form a rock.

Borax can be toxic for human. It causes irritation on the eye and can be harmful if accidentally swallowed. Always keep any borax away from reach of children and pets.

Boric Acid vs Borax vs Diatomaceous Earth for Bed Bugs: What Is Better in Killing Bed Bugs?

Diatomaceous earth is similar to borax. In fact it is applied in the same manner as borax. You can set traps for pests like in this case, bed bugs. Sprinkle enough around the bed to keep the bed bugs away. Sprinkle some of the diatomaceous earth on the surface where the bed bugs are likely to crawl.

The effect of diatomaceous to that of borax is more or less the same. It causes damage to the exoskeleton dehydrating the bed bugs before the finally die.

To kill bed bugs with diatomaceous earth, you may be forced to combine it with other insecticides. It is practically impossible to get rid of the bed bugs with diatomaceous earth alone.

Having said that, clearly there is not so much difference when you use either of the two.

Boric acid on other pests is amazing but on bed bugs it is not effective in controlling the bed bugs.


From the post, it is now evident that boric acid is not a good method of getting rid of bed bugs. It is effectiveness in controlling bed bugs is practically impossible. You may need to combine with other methods to see results and this may take time.

In this regard, I highly recommend using other types of pesticides such as diatomaceous earth. If you find it overwhelming to get rid of bed bugs, you can as well call professionals.
