Review: Works but took multiple applications - This product kills silverfish quickly but I had a big infestation and it has taken some months to eradicate them as they lay eggs which can’t be seen and finally it would seem we have succeeded.

## Questions & Answers

**Q: Will this be dangerous for my house cat?**
A: Not sure 
but would have thought it would be fine it’s certainly less toxic than other similar products I have used

**Q: Can this be sprayed onto carpet and upholstery?**
A: I've not needed to spray upholstery and my floors are hardwood and tiled. I have though sprayed rugs without any ill effects or stains. This spray is completely odourless and clear. I find it most effective on tiled floors. At the start I was spraying certain areas twice weekly (bathroom/kitchen/utility) but now I find that it is effective for about a week or a little more between sprays. You don't need to saturate areas with the stuff - a light misting will do fine. A 500ml bottle lasts me about 6 weeks (I found 5 Litre ones much cheaper and got that after the first 500ml one)
When I started using the spray I was finding dead ones about 3 each day now I'm getting only 2 in a month! 
If you know where they are coming from then you can stop them completely. I live in a block of flats where they could be coming from beside above or below me so I don't know  the source. 
Rest assured that this spray works great and you're not wasting your money - but be patient.

**Q: Did kill book lice thanks ?**
A: It killed the silverfish and prevented more from coming into the house, but i dont know about book lice.

**Q: Does this come with spray nozzle**
A: Hi there, It comes as shown in the picture. Brilliant stuff, the only product that worked for me.
