Product Details

Did you know that only 5% of fleas live on your pet? Fleas have a complicated life-cycle, 95% of their life is spent in the form of eggs, larvae and pupae that are actually in your home. In real terms, that means that for every flea you see on your pet, there are potentially 20 more of its friends and family in your home.

Flea eggs, for instance, laid by adult female fleas, roll off pets' coats into any crevices (including carpets, rugs, pet bedding, skirting boards and floorboards). The hatching larvae burrow deep down to protect themselves in these crevices and soft furnishings where they turn into pupae. They can stay in this state for as long as a year but, eventually, they will develop into adult fleas, leap onto your pet as it passes and the life-cycle starts again.

The most effective way to protect your home from flea infestation is to use award winning Indorex® Defence household flea spray. It is sprayed directly onto carpets, rugs, flooring, skirting boards and other potential flea hideouts. Best used in conjunction with applying a good quality spot-on on all dogs and cats in the home, breaking the flea life cycle will wipe out the next generation of fleas and protect your home from infestations for up to a year. 

Indorex® is also approved by the HSE2 to control house dust mites which can be implicated as a trigger for allergic diseases in our pets as well as in people.


There is up to 12 months of environmental flea control in a single can, 1 can of Indorex® treats an average of 79 square metres, 3 bedroom home.

Before using Indorex® Defence Household Flea Spray ensure that all of your doors and windows are closed. You should remove your pets from the area to be treated and ensure all your pet’s bedding is washed on a hot cycle.

Start by shaking the can and removing the lid, hold the can upside down pointing it directly at the surface to be treated, at a distance of 50cm. Spray directly on all surfaces.

Once you have sprayed Indorex®,  leave the room and wait for half an hour before ventilating the area by opening the doors and windows for at least an hour. It is vital you vacuum all floors and upholstered furniture for 7 consecutive days after using Indorex®. The vibrations from the vacuum will make sure any unhatched pupae will hatch and be killed but the Indorex® you have used.
