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.

Brilliant - convenient yet it really works.
A vet recommended me to buy Indorex even though I'd used (what I believed to be) a similar product without success. I followed exactly the instructions for the application of Indorex - which was easier than the previous product where you had to evacuate for 4 hours - with Indorex it was close up and evacuate for 30 mins then ventilate for a further 60 minutes. Then vacuumed daily for 7 days. Coinciding with this, I also changed the spot-on product I was using on my dog from Fipronil to Prinovox (from the vet). Daily I had been using a flea comb since long before the use of Indorex. From 24 hours after the Indorex/Prinovox application - not even one flea on the flea comb despite very thorough daily inspections. It had been a very small but very persistent infestation (for the past few months) - prior to which I'd always found Fipronil very effective. I believe Fipronil is good for preventing but not eradicating an existing infestation. Going forwards I'll alternate monthly between Firponil & Prinovox because Prinovox doesn't protect against ticks. Hope not to need Indorex again but great to have a product that worked so quickly and thoroughly.

Replacing our can after ten years - great value.
Ten years after buying the first tin of Inodorex...here we are buying another.Ten years across two houses with 5 Cats in situ at all times. 5 active outdoor hunting Cats. One is practically employed by the RAF locally for his airfield Rabbit suppression.We've also hosted Pigeons, Mice, Rats and Voles, Rabbit and a Muntjac either in the utility room, under the fridge in the kitchen or under the bottom step of the stairs.In combination with the normal 'back of the neck' Flea treatment for our Cat gang, Indorex provides an environment that Fleas cannot live, thrive or breed in. It's safe to use if you follow the instructions and lasts for ages.

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.

Effective
My vet recommended this to me, very effective, good value for money, read instructions before use to ensure optimal safety for your pet. Easy to use, hoping I won't ever need to buy this again, however would be this product should I need to make a future purchase.

Excellent product
This used to be prescription only and cost around £60 a tin. I find it’s the only spray that works and is now available everywhere for a fraction of the price.I have 3 dogs and 2 cats so work on prevention rather than cure. When we get unwelcome visitors this spray works

Not up to scratch
Sadly this product did not come up to expectations. Maybe it’s a defective bottle but it doesn’t spray which is a drawback for something which is supposed to be a spray insecticide.
