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

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!

This works. It is a mess to clean up and you need to make sure pets or children can't get to it but it works. I started out with another product that was not such a mess maker and didn't have much luck. Once I added this, in about a week and still now several weeks later, no sign of anything. I put under my fridge and behind my stove. I am very happy with the effectiveness but I am not looking forward to cleaning it back up. However, it is definitely worth it to rid my home of these.

One must wear gloves and eye protection wear, and a mask, and follow the instructions, and use the sprayer that came with the product. Good for the value, because it lasts for up to six months before using again. There is a strong odor, so avoid breathing in while placing it in crevaces, etc.

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

Works really well after a few days, no rough in sight. Just make sure you clean effectively, take out trash, and put some rouch gel down
