## Questions & Answers

**Q: How often are you supposed to use this?**
A: You can use it as often as you need to.  The scent will fade after a few days and spiders may return.  I use it in my conservatory, around the roof edges (inside) where spiders nest in the crevices.  It does work, but if I see new cobwebs I give it another squirt.
Hope this helps.

**Q: How much water does the dispenser bottle hold? Is it only 20mls? Or should that be 200mls?**
A: Hi there and thank you for your question. There is a 20ml bottle of our repellent oil blend and a 200ml spray bottle for spraying the water diluted oil. Using our dilution instructions this will make up to 12 litres of repellent spray. Best wishes, Rob

**Q: How many ml of oil should I use per litre for the most effective results thank you**
A: Maths are not my strong point but I work it out to be 30 drops per litre. The instructions say 2-3 drops per 100 mls

**Q: Will this be effective in keeping cats away and stop them pooing on our bark we have in the garden?**
A: I don’t think so, a cat is too big. It’s generally for insects, don’t even think it would work on a mouse. But I have no evidence to support this. Why don’t you try to get your bark to be louder, hence scaring the cat away before it poos. But you have to get the right balance, cos if it’s frightened too much, it may poo even more. Good luck.
