What Is Boric Acid?

Boric Acid is a versatile chemical that has a number of different uses, not just for pest control. It can be used as an antiseptic for medical issues, a preservative for word and skins, a lubricant and even for pyrotechnics.

Boric acid is an odorless and natural occurring powder which is believed to be a safer method of pest control compared to other more hazardous synthetic chemical insecticides. To humans, it’s regarded to be as safe as ordinary table salt. However, to most pests, coming into contact with boric acid can be fatal, especially for cockroaches, ants, termites, silverfish and other common household insects.


How Boric Acid Works To Kill Pests

The mode of action for boric acid and what makes it so effective in the pest control industry is its ability to kill insects without the use of highly toxic chemicals. When applied, the product acts as a stomach poison to the insects which come into contact with the boric acid or consume it. The powder is very abrasive and can cut through the outer shell of numerous insects.

For instance, if roaches were to cross over boric acid, the slow killing chemical acts like shards of glass cutting them apart. The slow killing effect gives roaches a chance to return to the nest where it soon dies. Other cockroaches will then eat the dead carcass of a roach who consumed boric acid, which eventually kills them too. The cycle continues until the boric acid has more-or-less been exhausted or the queen herself has consumed some, killing her, which destroys the colony.

What gives boric acid an advantage over other pesticide options is boric acids residual effect. It can still continue to kill long after it has been applied, up to a year. It also has no repellent properties so target pests won’t know to stay away from treated areas.

 Why Buy These Products

Boric Acid History

Boric acid is a by product of minerals when contain boron, known as borates. Borates are said to have originated in dried salt lake beds of deserts or arid areas (for example is Death Valley, CA, Turkey, and China) or other geographic regions that expose similar deposits (such as the Andes Mountains in South America).


In 1702, Wilhelm Homberg would first create what was known as boric acid by mixing borax and mineral acids with water. The evaporating water left crystals of boric acid and was often called “Homberg’s salt.” European researchers soon discovered the compound’s properties as a mild antiseptic and eyewash. As time went by, engineers discovers other uses for boric acid, for instance Silly Putty was invented by mixing boric acid with silicone oil.


In 1948, boric acid would be registered in the US as an insecticide to control cockroaches, termites, fire ants, fleas, silverfish and many other irritating insects.


Because boric acid is so versatile, it has been formed and manipulated into a variety of different formulations. Some of these formulations include but are not limited to: boric acid dusts, boric acid powder, treatment for crack and crevices, emulsifiable concentrates, tablets, pellets, pastes and boric acid bait.


How Safe Is Boric Acid?

While it is likened to table salt in terms of the little harm it can do to humans, boric acid is still a poison, and in certain doses it can present dangers to humans and animals.


According to the Natural Pesticide Information Center, boric acid toxicity ranges from minor to serious. Minor toxicity usually results in skin and eye irritation. More serious toxicity can result in symptoms such as respiratory problems, muscle weakness and headaches.


In cases of extreme toxicity, boric acid can lead to kidney failure in people. To animals, boric acid toxicity is connected to blood conditions and problems with the endocrine system. Toxicity in pets tends to be more severe based on the animal's size. Smaller pets, such as dogs, cats and hamsters, are more likely to experience dangerous symptoms.


While boric acid can be a great low toxic way to eliminate pests in your home, often homeowners complain that it doesn’t give them successful results when they’ve used it. Usually the ineffectiveness has less to do with the boric acid itself and has more to do with how the boric acid is being applied. Take a look at some of the common mistakes DIYers make when applying boric acid and avoid these at all costs to achieve the best possible results.


Mistake #1: Applying Boric Acid Excessively

Applying way too much boric acid than is needed is perhaps the biggest mistake people make when using the product. Subtlety is the key when applying boric acid or any dust insecticide for that matter. Think about it: if a roach is crawling around and notices a big pile of boric acid, do you think they will go anywhere near it? If anything, the roach will cleverly go out of their way to avoid the product at all costs.


The saying “a little goes a long way” is spot on when it comes to boric acid treatment. You shouldn’t be visibly seeing trails and lines of boric acid. When applying boric acid, you should apply in a way that you hardly see anything coming out with your naked eyes. This is the reason why it’s better to use a handheld duster over the application tip that boric acid comes in because you’ll get nice controlled little puffs of dust that will hardly be seen but it will be sufficient enough to do damage to unsuspecting insects.


If you still decide to use the original squeeze bottles the boric acid comes in, make sure when you twist the cap open you only open it up so a very small amount comes out. Cover the opening with your finger, give the container a decent shake quickly apply a small puff onto the area. Repeat the process until the entire area or home is treated. This can prove to be tedious which again is why a handheld duster is a good option.


Mistake #2: Applying Boric Acid in the Wrong Areas

Just as important as the amount of boric acid you should be applying is where you apply boric acid. By applying boric acid in areas where your target insect is not active, or away from their harborage areas they’re living is ineffective. This is where learning about your target insect is key and what their tendencies are as well as their hot spots. Once you have the knowledge, you can then strategically dusts the prime areas and not waste the boric acid (or your time) applying dust where it is not needed.


Most insects like cockroaches and ants like dark secluded areas, so applying the boric acid in spots like under the stove, refrigerators, and the hollow spaces underneath cabinets are good places to focus your treatment. You should also observe cracks, or openings in the walls nearby and apply boric acid accordingly.


A good trick if you have a cockroach infestation for instances is to leave the lights off (in the kitchen for instance). Then walk into the kitchen and turn the lights on. Observe the roaches that are out and about and see where they are concentrated. They will scatter quickly so you should take note of those areas and remember quickly. This will give you clues as to where to spot treat with boric acid.


Mistake #3 – Relying Solely On Boric Acid

Boric acid is a fantastic product, but when people hear about how great it is, they erroneous feel that it’s the lone solution to all their infestation problems. What this does is it limits your success rate. No one product will eliminate an entire infestation of whatever you may be dealing with. Experts all agree that pest control products, including boric acid, you be used complementary with other products in order to totally eradicate an infestation. However, much like chemistry, it is important to know what boric acid will mesh well with and what it won’t.

What Not To Use With Boric Acid


When it comes to products which don’t mesh well with a boric acid treatment are glue boards and glue traps. For example, a cockroach who is killed via being exposed to boric acid can aid you in killing other cockroaches due to the fact that cockroaches will eat other dead roaches. However, if the affected cockroach isn’t able to make it back to the nest because it’s stuck in a glue trap, you have essentially messed up a potential domino effect of multitudes of cockroaches dying at the hands of one boric acid-affected cockroach.


Another type of product which will not work with boric acid are those fast killing insecticide sprays such as Pyrid Aerosol and Novacide Flea and Tick Killer. While these products do deliver instant results by killing insects like ants and roaches quickly, they don’t help if you have boric acid laid out. You may kill a handful of roaches you personally see with these sprays but keep in mind that there are hundreds which are nesting somewhere you can’t see and that’s what you really need to kill to do away with the infestation.


Also any sort of repellent spray will basically nullify the effectiveness of the boric acid. If you’re spraying repellent in areas where boric acid is laid out, the insects will not go near the boric acid. Insects don’t die from repellent, they just learn to stay away from where you sprayed it.

What To Use With Boric Acid

If you’re dealing with cockroaches or ants, then a cockroach bait (such as Apex Cockroach Gel Bait) or an ant bait (such as Ant-Trax Ant Gel Bait) will work fantastic in tandem with boric acid. As we noted above, a roach which comes in contact with a bait and succumbs to its effects will become a killer of cockroaches due to roaches feeding off the dead carcass, much like how boric acid works. In fact, some gel baits use boric acid as the active ingredient to kill target insects.


Another plus to using these gel baits is they’re mixed with a powerful attractant that roaches and ants will find irresistable. You can also apply the bait in areas where boric acid powder isn’t practical.


How To Use Boric Acid Effectively

There are a number of ways in which you can use boric acid to achieve maximum results when treating for pest control:

  • To treat for roaches: Apply boric acid on top of high cabinets and shelves for roach control. Roaches prefer to hide in areas that are high and out of reach from us humans and will often travel to such areas and travel on them. You may notice them also on top of your fridgerator or in high corners of the room where the air vents are. By sprinkling some boric acid in these areas the roaches will bring the powder back to their nests on their bodies, ideally resulting in a desired domino effect that will take out the entire population.

  • To treat for ants: Distribute boric acid anywhere you notice ant activity. Ants usually travel in trails around the floorboards. By placing boric acid in the areas where they make their trails, the ants will likely eat it and return it back to their colony to share with others. You can also create little boric acid bait balls by mixing boric acid with sugar (to make it appealling to sugar loving ants)  with water. Place these around and the ants will carry pieces of the balls to their nest and poison the ants which eat the mixture.

  • To treat for fleas: Spread boric acid on your floors to eliminate fleas from your home. Apply boric acid power to your home carpeting, then use a broom to work it well into the carpet so it reaches deep into the fibers of your carpet. Move the broom back and forth until you no longer see the powder. You can also dush the powder onto furniture and work it in with a small hand broom. Since boric acid is typically more effective in eliminating adult fleas rather than larvae, you may have to repeat the process in a few weeks when the next generation hatches and transitions into adulthood to eliminate all of the fleas.
