Two UV fluorescent bulbs produce warm light to attract insects to the M3 mosquito trap. The TiO2 - titanium dioxide exclusive coated funnel produces CO2 which is irresistible to mosquitoes, luring the insects to the powerful yet whisper quiet vacuum fan. Insects are collected and trapped into the retaining cage, where the insects expire naturally. Unlike other mosquito control solutions, the M3 Mosquito Trap has no "popping" sound to disturb your outdoor enjoyment. Simply hang the M3 Mosquito Trap, and mosquitoes stay away. Perfect to use in your backyards, barn, patio areas, gardens, porch and near swimming pools
