For the 13th year running the brand Indorex® - the UK’s number 1 household flea spray* from Virbac, has been voted by the readers of Your Dog Magazine as ‘The Best Flea Product for the Home’ 2021! Your Cat readers also confirmed that Indorex® is their firm favourite, winning their award for the 9th year running!

Regular treatment for the pet and effective environmental control provides a proactive and integrated approach to flea control and is the best way to protect pets from these common parasites. 95% of any flea population lives in the environment, with just 5% on the pet itself, so the use of a good household flea spray is the only way to achieve total flea control.
