## Questions & Answers

**Q: Would this be ok to use if you have dogs?**
A: Hi, yes providing the dogs are kept out of the room you're treating until the spray has fully dried (roughly 1 hour).

**Q: Can you use on house plant soil?**
A: I wouldn’t - you have to wear a mask to spray it and then leave the room for a couple hours
So that can’t be good for soil

**Q: Can it be used indoor?**
A: I normally use it around the window frames outside just on the edge so bordering the inside frame but please follow instructions and wear the mask (although we are all wearing them these days ) it leaves a bit of a fly killer smell but it soon goes and it’s worked for me !! 
I never saw a cluster fly at all last year probably get two or three applications out of it depending on how many Windows and doors you have but it’s good stuff !! 
Happy spraying 😹

**Q: Can this be used for regular house flies?**
A: I wouldn’t be spraying freely around house. It is strong and should be left for hour before reentering room. I have only used it around window frames where cluster flies gather.
