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.

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

Works very well killing ant nests. I also use a teaspoon in a pint of warm water to apply to my dog's pink eye. Within hours the pink eye is gone. Usually takes 3 applications, an hour apart. My dog is a chihuahua, so a bigger dog make take more.

Love fine powder instead of granular. Very satisfied with size for the money.

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.

What’s the be like a very nice fine 99.999% powder. Which is exactly what I was looking for! Going to be using this boric acid in the spring as a trap to catch wasps and hornets and take it back to their hive. Apparently, in the spring if you set them up, you’ll get the queens, which will then kill their hives. Once it’s slightly warms up, I’m setting it up. Apple cider, couple teaspoons of this boric acid, placed in a can with a stick in it. If I can reduce that hornet population by fall, that would be wonderful. They get very aggressive when I’m barbecuing outside. Almost at a point where I’m running in and out of the house because of these wasps and hornets trying to get into the food and so forth. Just as well, I’ll probably buy again.

Great to mix with peroxide to clear up dog ear infections. Also, love that it's in powder form which disolves.

Just what I needed to deter ants in my house.
