Using attractants is critical to the performance of your Mosquito Magnet®. Once mosquitoes sense the carbon dioxide from the Mosquito Magnet®, they need secondary attractants, Octenol or Lurex3™, to hone in on the trap.  Choose Lurex3 for hard-to-catch, aggressive day-biters such as the Asian Tiger mosquito, or if you live in the Southern US region, or Hawaii.  See MAP.
