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! Review: Late review...but this stuff earned it πŸ˜‚ - I bought this back in August 2025, so this review is about a year overdue. I was scrolling desertcart 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... πŸͺ³πŸͺ³πŸͺ³ 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 πŸ˜‚, 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. πŸ™Œ 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 πŸ˜‚. 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 🀞πŸͺ³, 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 😎 ## Features - Long Lasting - Continues to kill roaches, palmetto bugs, water bugs and silverfish for weeks after application as long as it's kept dry - Fast Acting - Insects coming into contact with the powder will die within 72 hours after initial contact - Easy Application - The powder duster with extended straw makes application quick and simple for difficult to reach areas - Contains Irresistible Lure - Harris food grade lure attracts roaches from their hiding places - EPA Registered - Made in the USA & Registered with the Environmental Protection Agency (No. 3-10) for use in homes with people and pets ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079J5XF31 | | Active Ingredients | boric,boric acid | | Best Sellers Rank | #3,871 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #89 in Pest Control Baits & Lures | | Brand | HARRIS | | Brand Name | HARRIS | | Customer Reviews | 4.2 out of 5 stars 4,860 Reviews | | Item Form | Powder | | Item Weight | 2 pounds | | Manufacturer | Harris | | Model Number | HRP-32P | | Part Number | HRP-32P | | Specification Met | EPA | | Target Species | Insects | | UPC | 072725099539 | | Unit Count | 32 Ounce | ## Product Details - **Active Ingredients:** boric,boric acid - **Brand:** HARRIS - **Item Form:** Powder - **Item Weight:** 2 pounds - **Specification Met:** EPA ## Images ![Harris Boric Acid Roach and Silverfish Killer Powder w/Lure, Powder Duster Included in The Bag (32oz) - Image 1](https://m.media-amazon.com/images/I/717KHF6uVZL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this safe under a dishwasher?** A: Yes, as long as you don't eat off the floor under the dishwasher. **Q: After you spread the powder, do you see the roaches die on the floor , or it take days or week.** A: This Boric Acid will absolutely kill All roaches, however it will happen slowly over a period of a few weeks. The roaches track it back to the hiding places and it distroys all eggs and other bugs. This is the way to finally be rid of roaches. We did it 4 years ago and have only seen 3 that maybe came in thru garage or open doors. Put it anywhere there is a hiding place, the pump is very good for under cabinets and under appliances. Cover all entrances . Do it and be rid of them! I don’t think It will hurt anything. Nothing at our place, that I know of.😎 **Q: This is a powder to spray onto hard to get area's not tablets?** A: Yes! It comes with a plastic accordion pump that scatters a thin cloud for you. Remember roaches lick their appendages. That small amount in ANY super narrow space will be their death. **Q: Can this be used outdoors? I need the most potent toxic killer for a yard barrier** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Scorpio Dolly *by S***Y on August 8, 2026* This product is amazing!

BEST *by O***N on July 17, 2026* 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. ## Frequently Bought Together - Harris Boric Acid Roach and Silverfish Killer Powder w/Lure, Powder Duster Included in The Bag (32oz) - Advion Cockroach Gel Bait, 4 Tubes x 30-Grams, 1 Plunger and 2 Tips, German Roach Insect Pest Control, Indoor and Outdoor Use, Roach Killer Gel for American, German and Other Major Cockroach Species - HARRIS Boric Acid Roach and Silverfish Killer Powder w/Lure for Insects (16oz) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/58314201-harris-boric-acid-roach-and-silverfish-killer-powder-w-lure](https://www.desertcart.pt/products/58314201-harris-boric-acid-roach-and-silverfish-killer-powder-w-lure) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-13*
