Indorex Defence Household Flea Spray is the UK's No.1 household flea spray, killing adult fleas and dust mites for up to 2 months after application.
This product will be dispatched by our P2U partner. More info
Indorex Defence is a vet-recommended household spray designed to protect your living space from flea infestations and dust mites. It works quickly on contact to kill adult pests and continues working long after application.
Unlike treatments that only target adult fleas, Indorex Defence also prevents eggs and larvae from developing for up to 12 months. This breaks the flea life cycle and helps stop re-infestations before they start.
Thanks to its UV-stable formula, Indorex Defence remains effective even in sun-exposed areas like conservatories, cars, and windowsills—places where other sprays can lose potency.
A single 500 ml can is enough to treat the average 3–4 bedroom home, making it a cost-effective choice for complete household protection.
Shake well before use and spray from about half a metre away, focusing on carpets, skirting boards, rugs, and pet bedding areas. Allow the spray to settle before ventilating the room, then vacuum daily for a week to help expose any hatching pests to the treatment.
