Indorex is the number one selling veterinary household flea spray on the market, voted Best Product by readers of ‘Your Dog’ magazine 2 years running, and with so many benefits it is easy to see why! Indorex has a higher Permethrin content than any other household flea spray which means it gives your home the longest protection against adult fleas and dust mites, killing them on contact in minutes for up to 2 months. Piperonyl Butoxide enhances the action of Permethrin, ensuring maximum speed of kill and ensuring the effects last. Permethrin has an excellent safety record and is used in many animal products. Not only does Indorex control adult fleas and dust mites in the home, it also contains Piriproxyfen to prevent flea and dust mite eggs and larvae hatching for 12 months. Piriproxyfen has no known side effects in humans, dogs or cats. So you can rest assured that one treatment with Indorex provides a year’s worth of safe, effective protection for your home. Indorex is pleasant to use as it is completely odourless and provides excellent value for money, with one can covering 79m² (treatable surfaces in an average 3 bedroom semi-detached house).
Indorex should never be applied directly to the animal (especially cats). It is for use on surfaces in the home.
For best results:
- Close windows and doors before spraying
- Spray inside your vacuum cleaner as fleas survive in dust
- Remove pets and seal fish tank lids before use

Treated rooms & rooms with vinyl flooring
15th Sep 2017
After a room has been treated, how long should I allow before letting my cat back in it?
Should I use this product on vinyl flooring too?
Thank you for your question.
You need to leave at least an hour before letting any pets back in the room.
You can use it on vinyl flooring as well.

I have a leather lounge suite which my cat frequents daily. Can I use the spray on it?
You should be safe to do this, but first you should spray a small patch on the back of one of them and leave it for a few hours to test it out. If there is any colour change then it is best to avoid using it
Is it safe to use with 6 week old kittens?
Ideally you should not spray this while the kittens are present. Once the spray has settled out of the air (one or two hours is plenty of time) then it is perfectly safe for your kittens.
Can you use the spray if pregnant?
Yes you can, but personally I would suggest that you ask someone else to actually apply the spray. Once the spray has had an hour or two to settle out of the air, it leaves a minute film of insecticide on the floors and low surfaces but will not affect a person in the room. If you apply the spray yourself inevitably you will inhale a tiny amount. This should be safe in fact, but it is better to be over-cautious with this sort of thing, especially in early pregnancy (first 3 months). Ideally have someone else do the spraying for you.
I have a 1 year old in the house is it safe to use

I have a 1 year old in the house is it safe to use
I would recommend that you keep the child out of any treated room for the first couple of hours after you have used the spray. After that time, all of the product will have settled from the air onto the floor coverings and other surfaces. It is then fine for your child. (Even if he/her went around licking the floors, I would be more worried about other things than the Indorex!)
How long until I can see results

how long to see the fleas die
If I spray bedding and furniture how long until I can see & feel results
This will start killing fleas immediately. The trouble with fleas is that they are very well adapted to surviving and breeding out of sight, so some fleas will continue to appear from places out of reach of any treatments for a while. Any fleas you see might already be "poorly" (ie affected by the Indorex or other treatments) by the time you see them, but each flea might take a few hours to die. "Sick" fleas are particularly easy to find, as they are not so good at hiding and escaping. Fleas will appear "from the woodwork" for a period of time. Ideally you should treat all dogs and cats in the household with a spot-on flea treatments like Advantage or Frontline as well as using Indorex around the house. Most people see results after a few days, but sometimes it can take up to 2 months if there is a heavy infestation and many flea eggs have been laid away from the areas where you can reach with the Indorex (this happens especially in houses with both dogs and cats). All you can do is treat the animals and the house and wait for the flea population to decline. It always does, but sometimes it takes time.
Kids and pets
6th Sep 2015
How long will pets & kids need to be kept out of treated area? Can I use it on soft toys bedding etc?
Pets and children need to be kept out of a treated area until the air has cleared and all the spray has settled down onto the floor or other surfaces. This will only take an hour or two if there is minimal air movent. After this period of time you can open windows and doors for a short while to clear the air and then it is very quickly perfectly acceptable for pets and children to be present. The only thing I would say is that if you have a fish tank, it is best to make sure this is covered and any air pumps are switched off while the air is clearing. As far as spraying soft toys and bedding, I personally advise not doing this, but putting those things through the washing machine instead. This will be effective, certainly if you can use a hot wash, and leaves no residues of course. Ideally you would wash these items periodically to keep them clear.

Is it safe to use on mattresses and pillows, and wooden floors
Yes Indorex is suitable for use on all these surfaces. You should treat all flooring and soft furnishings in the rooms where your pet has been, right up to the corners of each room.
Safe For Reptiles?
11th Apr 2015
We have 17 Reptiles in one room and another one in another room. Are they safe to be left in the rooms while being treated? We have absolutely ZERO ways of moving them out....
Indorex spray has a very low toxicity for most species so the risks for your reptiles are low. I would suggest that while you are actually spraying the Indorex you close any vents on the vivaria or simply cover them over with sheets or something similar. When the spray has mostly settled, which does not take very long (say 15 minutes if the air is still), then open windows and doors in the rooms to make sure the air in the room is clear. Then a short while later you can open the vents on the vivaria/remove the covers. The Indorex will then be on the floor etc but not in the air, and it will be safe for your reptiles.
Flea control in home

My dogs have fleas but i cant spot any around my home, which areas should i treat?
The entire floors of the whole house. You are unlikely ever to see the fleas there, let alone the tiny flea eggs and larvae. They get lost in the nooks and crannies between floor boards, in rugs, under skirting boards etc. They are usually at ground level, but can be on furnishings if your pets go there (such as on the sofa). They are very small.
