Boric Acid


Summary: It's the all-purpose insecticide that does it all. Boric acid is used to kill ants, spiders, cockroaches, wood boring beetles, and fleas. Boric acid can stop and repair wood rot, too.

Boric acid is a colorless, odorless powder derived from borates that occurs naturally in soil, rocks, and seawater.

Besides pest control, boric acid has many uses that are very beneficial to mankind. It can be used as an antiseptic to sterilize wounds and as eye drops in a diluted form. It does everything from curing athlete's foot to treating vaginal yeast infections. It soaks up moisture and kills fungus which makes it good for treating wood rot. Boric acid can be used to prevent wood boring beetles, too. It is used as a flame retardant and even used in nuclear power plants to regulate the fission of uranium. It is practically non-toxic to humans,

mammals, birds, fish, and many beneficial insects such as bees.

And, if all those Boric acid uses are not enough, it can be used to kill fire ants, spiders, cockroaches, fleas, termites, beetles, and silverfish in widely available pesticides. The boric acid sticks to the legs of the insect when coming in contact with it, then the insect ingests it when grooming. It also acts as an abrasive on their exoskeleton.

Boric acid works slowly, it takes three to ten days to kill an insect using boric acid. This can be a good thing because boric acid is often combined with a food attractant in baits. The insect will eat a little of the bait, the boric acid sticks to them, and they carry it back to their nest where it spreads to the other insects living there.

Boric acid is effective in killing termite, ant, and cockroach colonies. too. It is available as aerosols, liquids, granules, wettable powders, dusts, pellets, and in combination with other ingredients as in baits.

To treat against cockroaches the boric acid should be applied into cracks and crevices in the kitchen, bathroom, and basement. Sprinkle some under the fridge, oven, dishwasher, microwave, and washer and dryer. It can also be applied above cabinets or between cracks in shelves. Basically, dust the boric acid powder into the small places where the roaches might like to hide. Under the kitchen sink between the water pipes is another great place to put it to

prevent roaches.

Boric acid can be used to get rid of fleas by putting it into carpets and dog beds. By working the powder down into the carpet you can kill fleas and the flea eggs. Vacuum the carpets thoroughly before you apply it and leave it in for a couple of weeks. It won't leave any stains.

One word of caution: Pregnant women should not use boric acid because of possible pregnancy complications. So, that means "heads up" on the following products: Flea Stoppers, Mop Up, Bora-Care, Jecta, Niban, and Timbor, plus others that contain boric acid. 

One more cool use of boric acid is utilized by jugglers and performing artists. When boric acid is combined with methanol it produces a bright green flame when it is burned. Just thought you would want to know this in case you were thinking about starting a flea circus and were looking for some great effects.

Ok, so that is Boric Acid. It's an all-around tool. Granted, it is not the fasting acting pesticide, but it is fairly safe for use around the house. As always, we urge you to carefully read the label of an insecticide and follow the directions.

Does Boric Acid kill lice? I want to dust my room with it but don't know if it will help.

Boric acid is a pesticide that kills a long list of insects if they come in contact with it, lice included. It only requires a very, very thin film of the stuff. Too often people over-apply.

Gabe,

Boric acid is not the best method for treating termites.

Great article, but I still am having small pesky ants in my house. I mixed 2 TBS of Boric acid with 2 cups sugar and one cup water. I also have this liquid ant bait (brand name Pic) and bait holders. Ants have been feeding off these baits for about 10 days in the windowsill of my bedroom. Everyday when I come home there are at least 50 ants eating the bait (10 days), and the numbers are not decreasing. They also seem to be everywhere this year in my house. My wife is pregnant, so I don't want to spray the house, should I use more boric acid in the solution I have?

Thank you!

I think this is a little far fetched, but my little black ants don't seem to like it mixed with jam, but they like it on salami! I chopped some salami very fine and mixed in some boric acid and the ants are in a FEEDING FRENZY! This was about 24 hours ago....I have placed these all around the outside of the house, and a few at their main sites indoors under sinks.
any idea how long I need to keep this up before they die? It appears we have several billion of these ants in several colonies around the house....

Not far fetched, at all. Certain ants like sweets, while others prefer protein or fat. And, their preferences may change. All depends on the ant species. That's why identification is so important.

Is boric acid safe around children. For example, the use of it, of course in small amounts as you have advised, in a toddler's play room full of toys to kill spiders? Thank you.

Boric acid should be applied as a very fine film. You should not really notice it laying on the floor. Too many people apply white lines of the stuff, which is misapplied. Do it right and your kids will be fine.

Crickets seem to love my favorite house plant. Can I sprinkle boric acid on the soil, or it there a better way to get rid of them?

Sorry, but the label says nothing about using boric acid on house plants. The manufacturer says "no".

I've noticed huge palmetto bugs lately, I usually only see one at a time, then the next day it's dead, but the past month or so I've seen 3-5 of them, which concerns me. There's a vacant unit next to mine, plus an outside storage room, both of which are probably very hot inside, so I'm guessing they're coming from there.

However, I've also noticed carpenter ants here and there, a lone one upstairs, or in the bathroom, or wandering around lost. The other day I noticed a couple run away when I opened a cabinet. Maybe the palmetto bugs are there for the ants?

Sounds like boric acid is needed badly, as I don't like pesticides.

Carpenter ants are there for some hidden moisture content. Better check it out. Their presence usually means a water problem in the gutters or inside a wall.

The Palmetto bugs live outside and find their way inside by locating cool air escaping from your home. Seal up as many cracks as you can find to keep them out.

Hi! I have silverfish in my apartment. I have tried little non-poisonous traps to catch them, but I would like to use boric acid to cover a wider area. What can I buy? Should I just buy straight up boric acid and sprinkle it under the fridge, dishwasher, washer, near cracks, crevices, under the sink, etc.? Help me please! I can't stand these little creepy crawlies!
Ask the Exterminator

You don't need to buy anything. You just need to find the moisture source and eliminate it. It might be sweating pipes inside walls or other leak, but resolving the moisture will do in the silverfish.

i have recently found that my "rock garden" has quite a few termites in it.. now granted the garden is mostly rock but it is also quite a few bushes and my rose bushes are growing there. would it be ok to use boric acid lightly all over my garden or is there another option..please take into consideration I am living paycheck to paycheck. any extra expenses that cost quite a lot are really not an option..

Termites eat only dead and decaying wood. Your rose bushes are safe. Boric acid, by the way, has no label uses for outdoor insect activity.

I have a roach infestation-yuck! Am trying to get rid of them especially because of my 5 yr old daughter...should i put some in the kitchen cabinets or is it enough to put it in the cracks and crevaces along the floor areas? and if i mix it with sugar wont that just attract more bugs instead of getting rid of them? Thanks!

Hi,
i have problem with slugs and white cabbage caterpilars. And I read about boric acid to be used as pesticides. Do you think i can use it and how, or which kind of form, as a powder or as a solution?
And is it harmful for slugs as well, due to absorbing water?
Thanks a lot.

I have little white spiders in my house. They seem to appear in late summer early fall. They are all over and have bitten my daughter. How should I apply the boric acid powder and what type would be best to use in this case? Thank you for your help.
