Don't settle for short-term mosquito relief. Kill and prevent mosquitoes with the Ortho® Home Defense® mosquito kill and prevent station. Backed by scientific research, this system uses mosquitoes own breeding behavior against them to control mosquito populations over time. This contained and targeted approach doesn't use broadcast sprays, repellents, flames or batteries and is easy to set-up and maintain for continued mosquito control. It's technology that's available to pest control pros, now available at a DIY price. How it works - Attract - the station mimics the ideal breeding site to lure in adult mosquitoes. Contaminate - once inside, mosquitoes lay their eggs while also becoming contaminated with a dual-action formula. Spread - adult mosquitoes exit the station and continue breeding, spreading the formula to the other sites they visit. Control - adult mosquitoes die within 9 days. Mosquito larvae inside the station and at the other sites adults have visited are killed by the formula. This system effectively kills and prevents new mosquitoes from developing.
