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 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.

Got bugs? Get this! Pro-tip: Mix the powder with a bit of sugar water, drizzle around edges, and bugs will swarm it! They even take some back to share with the Queen. Sayonara bugs! Second pro tip: Once the bag is empty you can buy *food grade* diatomaceous earth, (must be food grade), put it in the puffer, and puff it around edges and into cracks. It also works on garden plants and lawns. Death to bugs without dangerous chemicals.

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

Not saying I got rid of all the palmetto bugs in my house, but I got rid of about 95%! There’s still the stragglers who are probably hibernating, see then why nice in a while. But mostly all babies are gone because im pretty sure I got rid of the female adults. This will only work if you do it correctly! For any bad reviews, means they didn’t do it right, or they didn’t read!! This does not work great on German, but still helps I love heard. Because boric acid is the only thing that the German species can’t get immune to. Thankfully I didn’t have those. I live in Fla, land of the palmetto! Anyway, TIP: Less is more! Do not over puff everywhere. If they see a pile of powder, they will walk around it. They don’t like this stuff, they don’t hate this stuff. If they see it, they will not eat it. That’s not how it works. You want to dust a fine layer in areas you have seen them. Then, they walk over it, and once it gets on their legs, they lick it off to clean their legs, and that’s how they ingest it. Then, hopefully, when they die, it’s at the nest, because the other roaches will eat the poisoned one, they are cannibals, and they will die also. HUGE TIP: The only place these things can hide where you can get to them is in your walls. So, although unorthodox, I drilled small enough holes every 20 inches for duster to fit in. I did this through my hole house. I dusted in every hole lightly but just enough. Then I got some quick dry putty, and painted over, even though it dried white. I still painted anyway. So that method doubled my success rate! It’s up to you, but when they fall on one of your kids bed! Your going to do things that you normally would not to get rid of them. Good luck. Oh, btw, that powder will stay in your walls forever as long as it doesn’t get wet. So, lifetime protection in wall!! Lol

I dislike the smell of course it's baited so it's gonna stink, the dusters don't work really well they tend to clog which is annoying but the product itself is fine a turkey baster would he more effective then the duster, it controlled the bugs a bit but they seemed to just roam and It didn't reduce until I put half and half of diatomaceous earth and this stuff

This is great for outdoor roach defense! We used it all along the backyard and it has a powder pump straw that helps you really pump the boric acid into the cracks and openings that roaches and other bugs come out from. We had a bad roach problem outside of our home and this helped kill them almost immediately. Great product, highly recommended!
