    CB Borid Boric Acid Dust

    By Darlene on 07/22/2010

    My mother has always used Boric Acid Dust Powder Roach Killer for years and swears by it. In every house we ever rented or owned this item was the first thing she used before moving in. It really kills bugs and cockroaches which she really hates. This really keeps them away. She actually travels with a 5oz powder bottle - she hates bugs that much! I really appreciate that it comes in 5 lbs (and more). I use it inside and outside my home. Thanks, for the fast delivery too. I have recommended your site to many of my friends.

    Exceeded expectations

    By Joe on 10/30/2010

    For years I had heard the wonders of Boric acid but assumed that like everything else, it was over-rated. To my surprise and delight, I was wrong. The stuff does kill ants fast. No mess, no smell, no dead bugs lying about. They just went away! After my ant victory, I decided to test a few of the claims I'd heard of it's efficacy as a general disinfectant and mold-fighting agent. It works! DoMyOwnPestControl.com was great to work with. Great prices without the typical shipping charge gouge so common with many other Internet retailers. I recommend both the product and the company selling it.

    Great against Cockroaches!

    By Ibasic on 09/18/2011

    Verified Purchase

    I just moved in in my new apartment, everything was clean and new but in the first couple of days I saw one roach every night in the kitchen. I was really scared that there were dozens more that I don't see and bought this acid dust. I've put it in all cracks and devices and from the second day on I only saw 3 roaches, but dead ones! Now, two weeks later, I always keep looking out for them in the night, but there has not been one of them! This is great and I can only recommend it...

    It works on water bugs

    By Sara on 08/30/2011

    I purchased this for both an indoor flea problem from our cat bringing them in and an infestation of water bugs that came in with new flooring we had installed. I was fortunate in that I found the nest of water bugs in an old toy chest in our garage that I was able to remove and take care of a big chunk of the problem. For the remainder of the problem, I swept the boric acid dust in the crack between the flooring and walls, behind the washer and dryer, and for the fleas in our laundry room along the baseboards. I also used it along the foundation of the entire house outside. In the laundry room, I used a hand broom to push it into the carpet along the walls (Berber). After a few days, we started seeing dead water bugs. I was still seeing some live ones as well, but in the last few days I have not seen any live ones. I have not had any ill effects from using it, and my pets all seem just fine. I am finally seeing the fleas die off in the laundry room, but I cannot comment much on the effectiveness of the boric acid, as I have taken a 3-pronged approach with this room, using diatomaceous earth as well as intense vacuuming every other day or so in addition to the boric acid dust. I give it 4 stars and not 5 simply because it takes a lot of work to use it, but I would rather use this than a toxic spray.

Will Borid Boric Acid kill adult fleas & their unhatched eggs?
CB Borid Boric Acid Dust will kill adult fleas but it will not kill their eggs.  This particular formulation of boric acid is not labeled to broadcast over your carpet.  However, if you have fleas inside your home it is very important to use a product with an IGR in it when treating for fleas.  We do have an Indoor Flea Kit which has a dust product labeled for broadcasting over your carpet as well as Alpine Flea Insecticide Aerosol with IGR.

Will boric acid work for treating termites?

The ceilings in my house are all wood. I read that boric acid is a non toxic way to treat termites, and that it's efficacy will last forever if left undisturbed. However, in your product description, termites are not included as a "Target Pest".

Boric Acid dust is not a good way to treat wood.  You may be referring to Timbor, which is a boric acid dust that you mix with water and apply on wood.  However, Timbor will leave a white residue on wood.  Also it can only be applied to raw wood, it cannot be applied to any wood that is painted, stained, or sealed.  The best wood treatment product is called Bora-Care.  It will stay in the wood forever, and dries clear, but you still can only apply it to raw wood that is not painted or treated.
