Wouldn't it be nice to have a bite-free summer? The Mosquito Magnet can make that possible! Mosquitoes and other blood-sucking insects are attracted to carbon dioxide which humans emit. The 20-Gallon propane tank (not included) catalytically converts the gas into CO2 to mimic a human or "dinner". Place the magnet in the mosquitoes breeding or resting spot to catch them where they originate so they'll be attracted to the magnet and sucked into the net where they die, instead of going on a mission to eat you. In 6-8 weeks you eliminate these pests altogether by trapping the females and the unborn eggs.
