To protect your pet and your home from fleas, you need to break their life cycle - and that means treating your home as well as your pet. A household insecticide spray, Indorex kills adult fleas whilst also preventing development of their eggs and larvae. Acting on contact, not by ingestion, it kills adult fleas for two months and will protect your home from developing flea eggs and larvae for up to 12 months. It also kills house dust mites - a common allergen involved in allergic skin conditions in dogs. As a guide, one can of Indorex will protect 79 sq metres, the equivalent of an average 3 bed home. It is to be sprayed directly onto carpets, rugs, flooring, skirting boards and other potential flea hideouts.
