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.

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.

We live in a condo in Florida so roaches are normal, but we hate them. With this product I treat under appliances and cabinets and I never ever see bugs. Once a month is all it takes.

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!

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
