The Rentokil Flea Spray is a fast-acting, ready-to-use solution in a 300ml aerosol can designed to effectively eliminate fleas in the home. This flea killer is formulated for use on both hard surfaces and carpeted areas. In addition to a fast knockdown of fleas, it leaves a long-lasting insecticidal residue that helps provide extended control and protection against re-infestation for a number of weeks. The powerful aerosol is excellent for blasting and treating hard-to-reach areas, cracks, and crevices where flea eggs often hide, such as between floorboards or skirting boards. It is also effective against other crawling insects, including ants, wasps, woodlice, and cockroaches.
