Aqua Science Boric Acid Powder - 1lb, 99.9% Industrial-Grade Strength Fine Powder - Multipurpose Boric Acid Cleaner for Kitchen, Sink, Laundry, Stain Remover and Deodorizer - Made in USA Since 1983

I’m very satisfied with this 99.99% pure Boric Acid. The powder is extremely fine and easy to apply, which makes it very convenient to use. The container is sturdy and well sealed, giving confidence in the product’s quality right away. I’ve used it for different household purposes and it has worked perfectly. You can tell it’s a high-quality, pure product. The 1 lb size also lasts a long time, making it a great value for the price. I would definitely purchase it again and highly recommend it to anyone looking for a reliable and effective product.

The boric acid was of correct consistency and concentration. It is effective, dissolved easily and it was priced well for the value that I got.

This product looks pure and consistent. I bought it versus the plastic bottle that is being sold on Amazon that is only 1/2 filled with content. For use, I combined it with come powdered sugar and put the mixture in a condiment bottle (plastic). I then "sprayed" it under my refrigerator and dishwasher. In the 2 days that followed, cockroaches were dying on my kitchen floor and/or wobbling on their backs. Buy this powder. Excellent product

Great Quality. Kills roaches and other bugs very well. Lasts a long time once placed in a bugged spot

I used it around entry points and problem areas, and it significantly reduced the number of insects inside my house within a short time. It’s effective without being overwhelming or messy when applied carefully. I appreciate that it works gradually but consistently, and I noticed fewer bugs week after week. It gave me peace of mind knowing I had a reliable, low-effort solution.

Very fine powder. Works great. I will order again.

Ants and roaches are goners if they come in contact with boric acid. Plus it’s safe to use in our kitchen and pantry! I place it behind our refrigerator, store and under our kitchen sink! Plus anywhere the may be hiding or entering!

Boric acid is the only way I have found yet short of hiring an exterminator to eliminate the dreaded small brown roaches. The major box store in my area stopped carrying it and everything else has been a waste of time and money. If you are persistent in keeping powder out around any possible entry points including doors and windows along the walls in the cabinets and under the sink you will win the war with the brown roach guaranteed.
