Review: Cure, prevention and mutant fleas. - I have used Indorex for years now. At first I used it after a terrible flea season during which time we had 2 dogs and 3 cats. We seemed to be living in a flea infested hovel. The dogs, cats and humans were all itchy and incredibly grouchy and the fleas were obviously having the house party from heaven. Once I'd washed all the bedding, vacuumed everywhere and wiped the entire house down I sprayed this on everything. It worked impressively well and is so simple to use that I reckon my dog could have used it if all the humans had been eaten by mutant fleas. We use it as a preventative now by spraying twice to three times a year on all the soft furnishings, pet and human beds.. Our pets have no problem with it and as long as you stick to the instructions you won't choke to death. - Harmful by inhalation - Don't spray for too long otherwise you'll be seeing stars or those cute birdies from the cartoons. - Irritating to skin - So are fleas and dust mites, but just in case don't use this as a deodorant. - Extremely flammable - No flamethrower usage whilst spraying. As tempting as this might be, hold off til you're finished. - Vapours may cause drowsiness and dizziness - This is not a sleep aid. - Keep out of the reach of children - Unless you really don't like children. There are more warnings, but I inhaled too much spray and I am too dizzy to read them.
Review: Brilliant Flea Spray – Really Works! - I’m honestly so impressed with this flea spray. I’d tried a few others before with no luck, but this one worked almost straight away. The smell isn’t overpowering, it dries quickly, and it’s safe to use around pets once it’s settled, which gave me peace of mind. Within a day I noticed a huge difference — far less scratching and no more signs of fleas around the house. I used it on carpets, skirting boards, and the pet bedding, and it’s kept everything flea-free since. So easy to use and genuinely effective. Would definitely buy again!

## Questions & Answers

**Q: my dear friend who is 76 has flea bites will this get rid of house fleas she has NO animals?**
A: The fleas have completely gone after using Indorex! We have one Cat and treat him regularly but we found that once the fleas get into your carpets and lay eggs its extremely difficult to get rid of them, so make sure you spray the whole house. Its very easy to do and the cans go a long way. We are now able to finally relax, no more bites or fleas!

**Q: is indorex effective on bed bugs**
A: it worked for me adter 6 months of the council  trying with no hope insorex zapped the little beggers not had them since hope it helps you

**Q: DOES it work**
A: Yes, I have been recommended it by a friend who uses it to keep spiders out of their boat, when they aren't there and also by my daughter in law who has loads of animals and used to have a problem with fleas.  Just make sure your home is well ventilated when administering the spray around.

**Q: does it give a strong chemical smell?**
A: Not strong at all and disappeared very quickly when the room was ventilated  - very impressed

### ⭐⭐⭐⭐ Not too bad
*by C***S on 27 September 2025*

Tried the Frontline spray but it didn’t seem to do much so ordered this. It’s not perfect but it seems to be having more effect so fingers crossed
