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.

Highly recommend
Best flea spray. Our vet recommended we use this after buying a puppy who was infested with fleas. Even though he was only in the house an hour before he was treated for the fleas I didn’t want to take any risks. We were very kindly advised to go to Amazon to buy as the vet was selling it for £35 a bottle. It’s low adore and does the job.

Goodbye Fleas
I was looking at number of products which i could spray on the carpets and furniture in order to kill Fleas, and i decided on this, based on the reviews and Amazons excellent price compared to in store. The can is very large, and can quite easily do an entire house. I sprayed the entire carpet in one of my rooms, when it was empty. I left the room for 30 Minutes with the windows closed, and then came back and opened the window and left it for another 30 mins, and then hoovered the carpet. The fumes are very strong, and you aren't supposed to inhale them, so if your spraying a large room, i would recommend some form of mask in order to protect your self. Although it doesn't say its harmful/or toxic to humans, it does recommend on the can to cover your self. Ensure you read the can for the full instructions/warnings, as if you have any Fish, it could/can kill them if they are present in the room, and it will also tell you what else you can and cant do with it. Obviously, as Fleas are small, fast and black, actually seeing a result from the spray is very difficult. The can states it stops fleas from surviving for upto a year. However, it does not kill fleas which are older than 3 days, as they are to strong for the spray. Since spraying, i do admit the flea population has dwindled, after i also used Frontline on my cats, however, i still am suffering bites from fleas, and i have seen fleas on me in the room i sprayed. Therefore, i can only assume its because they are older than 3 days. I would recommend the product in order to cut down on fleas, especially from Amazon at this price. However, i would recommend De-Fleaing your animals in the process and continue regular hoovering of the rooms/furniture to assist the product.

Recommend. You have to be ON IT!
Works a charm! My entire house is carpeted so I made SURE to be on it! I had fleas in a different apartment many years ago and it was a nightmare. So I vowed to never let it happen ever again. Adopted a flea infested kitten but luckily my resident indoor/outdoor cat is flea treated with Bravecto. I had some 4fleas tablets on hand which I recommend in case of emergencies. (The tablets kill any fleas on the cat, but the eggs still need to be dealt with). Kitten was in one room for about 4 hours before I realised, so she was quarantined, combed and given 4fleas tablet. Then I took her to the vet that night and got Advocate spot on treatment to use a few days later. The next day I combed her and shampooed her in Bugaloos flea shampoo. 2 days after that I gave her Advocate spot on and at this point she was completely free of fleas and flea eggs. So I moved her to a different room and vacuumed sprayed everywhere in the house with indorex. The eggs can travel so I made sure to have everywhere sprayed! Once the fumes cleared, I moved her back to the quarantine room and treated the room I'd moved her into temporarily. In between all this i washed any clothing, blankets, pillowcases etc that she had come into contact with at 60°c. The fleas were eradicated long before they could even spread, and my house is still protected! It also genuinely works for spiders because I've not seen any in my house since either ☺️ It does smell strong and made me sneeze ALOT despite having the windows and doors open. I have asthma and I recommend using a mask as this really got me wheezing.

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!
