Super powder
Believe me! I was terrorized by german roaches for almost 2 years in the apartment where I live...Ive been trying to get rid of them from day 1... Raid spray kills them on contact but didnt get of the nest... My sister recommended this powder and used it 3wks ago as instructed and there population is down to 99%.....Some persons have the impression that the powder kills instantly..No ..for the first week I was seeing a lot of cockroaches about, but you can tell they were dying...I used the raid spray on them for a more speedy death.. I also ensure my garbage was out during the night seeing that these roaches comes out in their population in the night... Before I used the powder after thorough cleaning of kitchen and cupboards and feeling good about my efforts....low and behold in the dark of the night there is still an invasion of roaches in the kitchen...now even my kids have notice the difference...its Mummy I'm not seeing anymore roaches. I will see 1 or 2 popping up now and again.. but im ever on my alert to eliminate them...I give my God thanks every day...because I was dead sick of these roaches and now its like that burden has been lifted....I am not getting paid to write this but I am so satisfy with the result that I had to return to express my satisfaction about this product...My advise for those who are thinking about using this product.. use as instructed and just be patient and see the result after about a week or 2...Thumbs up all the way.

This stuff is magic!
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

Great roach defense and fast results!
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!

The powder is messy and the tool is difficult to use...
The powder is messy and didn't really work for me. The dispensing tool stopped working so I had to use a spoon to distribute the powder throughout my kitchen. For me, the roaches ran over the powder in small groups and continued to come out when the lights were off.
