Where to Buy Boric Acid for Ant Baits

Even a cursory reading of the posts on this site should have told you that boric acid is an effective technique for controlling ant infestations. Many people turn to the internet to answer a simple question: where to buy boric acid powder?

What is boric acid?

First, a little primer for those of you who are new to this site or otherwise unfamiliar with boric acid. Boric acid, also called hydrogen borate, is a compound with the chemical formula H3BO3. Its appearance is either colorless chrystals or a white powder. One reason some people are confused as to where to buy boric acid powder is that there is a similar product that is much easier to find: the laundry detergent Borax. For pest control, you can use either one.

Boric acid is popular for ant control for two reasons: It is a slow-acting poison that the ants carry back to the colony. There, when ingested, it acts as a stomach poison, and can wipe out the queen and other ants at the nest. (It also dries out insects’ exo-skeletons.) This delayed-action ant killer ensures that not only the foraging ants that are actually in your kitchen or bathroom die, but also the rest of the colony. Unlike a pesticide spray, that kills ants on contact, boric acid’s slow action gets to the root of the problem, i.e. the ant colony or nest itself.

The other reason boric acid is so popular for ant control is its low toxicity. Unlike many pesticides that are harmful even in small amounts of vapor or fume inhalation, boric acid must be ingested or inhaled in very large quantities to be dangerous. Additionally, it does not emit fumes or odors that linger in the air and cause bad smells or dangerous fumes. However, boric acid is not intended to be ingested; traps or baits containing it should be kept out of reach of pets or children who might come to eat it.

Boric acid is also toxic to plants, so avoid dusting it onto your houseplants or lawn.

How to use boric acid

Boric acid ant baits

To make your own boric acid ant baits, mix your boric acid powder with some sugar or other bait, depending on the species of ant you are trying to attract. When it is well mixed, add some water and syrup and stir until you have a medium syrupy consistency. This mixture can be poured into appropriately-sized containers. Poke holes n the sides or lid of the container to allow the ants easy access, and place in locations where you see ants.

Expect to see on increase in ants the first few days, as they will be attracted to your bait. Resist the urge to kill them! They will carry your poison back to the nest to wipe out their friends and family.

If you choose to make your own bait stations, you will want to purchase plain boric acid powder. Many commercially-sold powders include some form of bait or other chemicals; you may wish to avoid these, and choose plain boric acid powder, to tailor your bait specifically to the variety of ant that is the nuisance on your property.

Where to buy boric acid powder (raw ingredient):

Amazon: What don’t they have? Both ready-made baits, boric acid powder, and boric acid powder mixes.

Hardware/home stores: Lowe’s, Home Depot, etc. Wide selection of raw powder and ant control products.

Walmart: They have most everything, including various boric acid preparations, at low prices and low shipping.

Grocery stores/supermarkets: Most of these stores won’t carry boric acid, but they are likely to carry Borax, a laundry detergent with a similar chemical makeup that accomplishes the same thing. Just as effective.

Drugstores: Like the supermarkets, unlikely to carry boric acid, but you probably can find Borax.

Pool supply stores: Some people add borates to their pools to control the acidity levels. However, this is probably not a good source for pest control, unless you have limited options, because it comes in huge sacks, often with other chemical ingredients.

Many companies, such as Terro and Combat, produce commercial ant bait stations that contain boric acid as their active ingredient. These also contain some form of bait solution, often corn syrup, that attracts foraging ants. These commercial bait stations are an easy-to-use application of boric acid; you simply pop them out of their packages and place them in high-ant-traffic locations.
