How to Purchase Boric Acid

Lindsay Champion

Boric acid, which is also known as Acidum Boricum, boracic acid or orthoboric acid, is used as a laundry cleaning product, an antiseptic for use in medicine and an insecticide.

Obtaining Boric Acid

Boric acid is used as a cleaning product called Borax, puffed in very small quantities in homes to keep roaches, silverfish, ants and termites away, and it's used on cuts or burns to prevent infection. Although it might be tricky to find boric acid, you should be able to find it for any need, whether you are using it for an insecticide, a cleaner or an antiseptic.

  1. Go to your local pharmacy for medicinal boric acid. You should only use this type of boric acid on your skin and should not use it for cleaning or as an insecticide. Ask your pharmacist for the right type of boric acid; it might come in capsule form or as a small container of powder.

  2. Purchase Borax for cleaning at your local grocery store or drugstore. This boric acid can also be used as an insecticide if necessary. Do not use Borax on your skin or for medicinal purposes.

  3. Purchase boric acid insecticide at your local drugstore, such as Walgreens. Most Walgreens stores carry a boric acid insecticide that puffs the powder into an even coat, which can be puffed into corners of shelves and floors.

  4. Purchase boric acid online (see Resources). You can purchase boric acid of any kind online, but you must be sure that the boric acid you buy to treat cuts and burns is for medicinal use only. You should not use Borax or other over-the-counter boric acid on your skin.


Boric acid is inexpensive as a cleaning product, an insecticide and an antiseptic.


Boric acid is considered poisonous if inhaled.
