## 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

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
