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!

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.

Not too bad
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

Brilliant and fast working
After reading reviews for several products I went with this one and am so glad I did, after it arrived I looked the product up via google before using it and found very useful video instructions on their website, I purchased 2 cans and still had a bit left after treating my whole 2 bed house, it’s an older style build and some of the rooms are big. First I stripped all the beds and cushions of their covers, collecting up any clothing and blankets that had touched the floor or the cat or dog had been on, I put those in a big box in the kitchen and worked my through it all washing it at 60, Next I worked my way around the house trying to clear the floors as much as possible, wiping over non fabric items and placing them on the stripped beds and sofa, any soft toys I couldn’t wash were thoroughly hoovered before being placed on the beds. With all that done I hoovered the whole house emptying the Hoover in the outside bin before getting all the people and animals residing in our home out in the garden, Then I closed all the windows in the rooms I was spraying as instructed, put on a mask and sprayed the whole house pulling back the sofa and end table in the lounge to get underneath, making sure I did all the skirtings, spraying both under and on top of rugs, I made my way through each room so that I always finished at the door and closed the door of each room behind me when I was done, I then went outside with the rest of my family. 30 minutes later as per the video instructions I popped my mask back on and nipped around the house opening every inner door and window wide, (little tip I unlocked all of my locked windows before I sprayed to reduce the amount of time I had to spend on each room while getting the windows open after the 30 mins) before going back outside, a little over an hour later (video said 60 mins but we waited until the kids wanted to come in we ventured back into the house not only did the house smelt wonderfully fresh, but ever since we’ve not seen a single flea jump from the carpet either and I was getting bitten to pieces before, two particular areas where my kitten goes I would stand and at least 6 would instantly be on my feet and my son led down and had about 4 jump on him right away, I had a tonne of bites on the bottoms of my legs and feet all of which have nearly gone now and I’ve had no new ones since the spay. Then I put the house back right, hoovered the mattresses as instructed and made the beds, Now we are half way through our 7 consecutive days hoovering the house through which is another must according to the video instructions, because while the spray will kill the hatch ones there will still be eggs in the carpet, the vibrations of vacuuming encourage them to hatch and then the spray kills them too. As well as doing all of the above our animals are up to date on their flea treatments and we’ve been combing them through twice daily with nit combs. We got on top of the problem quickly which helps but this spray has worked amazingly and we’ve not had a single flea jump on us since using it, I was amazed at how quick and efficient it is, I highly recommend and intend to use it once a year as a preventative, Look on their website too though, it’s really informative, helps you fully understand the fleas life cycle and what you need to do to do a real thorough job and have your best chance of getting rid of them, On a side note we were also having an issue with loads of ants coming in at night, this seems to have deterred those too and we haven’t seen any of those since we’ve used it either, neither dead or alive so apparently they don’t like our house since using the spray either, win win in my eyes.

Defective item, refunded.
Arrived without a spray cap, unusable product. The seller refunded me the full price within a couple of days and resolved the issue promptly. I have used the spray before and know it works well, I just happened to get a defective bottle.
