Harris Boric Acid Roach and Silverfish Killer Powder w/Lure, Powder Duster Included in The Bag (32oz)

This product is amazing! I love the idea of the little canister to pour the powder in. It is easy to use and the little pointer attachment can go under the tinniest place to squeeze the powder in. It’s odorless and sprays out so freely. Already I am seeing roach reduction in my home. I like that it’s safe to use and the price is very affordable. Definitely a keeper!

Great item. to remove and. kill. roaches, ants and termites. I spray all over the outside of house....and sprinkle some powder also. The termites eat it and brings it back to nest, killing the queen. Ants also bring this back, and roaches eat it and are killed. I have almost no insects now.... Great items. Just do not use near kids. great price, saves and is cheaper than pest control company which uses toxic chemicals.

I bought this back in August 2025, so this review is about a year overdue. I was scrolling Amazon today, saw this product again, and immediately thought, "Wait...I NEED to leave a review for this!" For some context, my husband and I rent a home that we absolutely love. Our landlord has been great, but unfortunately the previous tenants left behind one very unwanted gift... 🪳🪳🪳 When we first moved in, we'd maybe see 1 roach a day in the kitchen. Annoying, but manageable. We kept everything clean - no crumbs, dishes washed, counters wiped down, trash taken out, etc. But somehow the problem just kept getting worse. One became five. Five became...I stopped counting 😭. At that point we realized we weren't just seeing roaches - we had a full-blown infestation 😭😩😱!! Like...a REALLY BAD one. I'm the overly proactive one in our marriage 😂, so I wasn't waiting around. I emptied every cabinet, deep cleaned everything, moved basically our entire kitchen into the dining room, and started researching products. That's when I found this boric acid powder. I applied it throughout the kitchen, and...it absolutely worked. 🙌 Now, if you're dealing with a serious infestation like we were, don't expect overnight miracles. In our case, it took about 4 months with the kitchen mostly torn apart so the powder could do its job. But the results were worth every bit of patience. Today, a year later, I can still walk into my kitchen, flip on the lights, and NOT have to carry a sandal as a weapon 😂. One thing I will mention: This powder sticks around. Even after cleaning, wiping, and vacuuming over the last year, I still occasionally find traces of it in little cracks and corners. That wasn't a dealbreaker for me, but it's something to be aware of. Overall, if you're dealing with a stubborn infestation, I genuinely recommend this product!! It wasn't an instant fix, but it was an effective one. Hopefully I never have to fight roaches again 🤞🪳, but if I do...this is absolutely the product I'd buy again. I still have plenty left over, (I'd say half the bag) so the extra could probably cover the rest 😎

This boric acid powder is effective when used correctly and in thin, targeted applications. I applied it in cracks, behind appliances, and along baseboards in light dusting layers. Results are not immediate, but over time pest activity in treated areas decreased. The key is restraint—too much powder reduces effectiveness because pests will avoid it. This works best as a maintenance or support product, not a standalone solution. Pros: ● Very affordable ● Long-lasting residual effect ● Works on multiple pests Cons: ● Easy to misuse (over-application) ● Slow results

Yes! Kills them fast!! After 20 years in my apt with no roaches, suddenly they start appearing. Owners exterminated but I did my own and Harris Boric Acid definitely got rid of them!!!

Product is simple but messy to apply with the applicator, there is a bit of a learning curve to get it to perform well. It is a type of plastic bellows that needs to be depressed so the product shoots from a long plastic tube. I had to experiment with pressure to find the correct amount so that I didn't have a mound or none at all. I finally gave up on it and applied the product with a chip brush, dipping it in product and dusting areas of concern, I found this method worked better than the applicator although the product would not penetrate deep into crevices it was irrelevant as it was effective. The product itself has a distinct, chemical odor that I found offensive but it is not overwhelming on application, although it is when stored. It works as advertised, I have not seen any type of crawling insect since application.

Puse el acido con matequilla de mani en toda la noches durante 1 sema y al fin de semana las cucarachas estabatan gorditas y mas cucarachas abia hasta agradecidas estana las cucarachaa que las alimente por 1 sema y no iso nada el producto q mal plan en gaatar $$

I have a step open kitchen trash can with lid and kitchen bag liner where I put my Great Dane's poop twice a day. I was having a problem with a cloud of newborn flies emerging every time I opened that trash can. It was horrifying. My yard was constantly full of flies, I was spending a lot of money on those fly trap bags but still couldn't get in front of the problem. I put this boric acid powder in an empty spice shaker on a shelf beside the trash can. Every time I put poop in the can I sprinkle a fine powder over the newest layer. After about a week, zero live flies were in the poop container. I was just hoping for a reduction, but this has been so effective that it completely kills them all. The result is that now I have hardly any flies in the yard laying eggs either. So I have reduced the fly population on my property to almost nothing. Fantastic product!
