This is the mosquito trap that emits light, vibrations, heat, and a scent to attract and kill mosquitoes across one acre. An LED light oscillates at frequencies that are proven to appeal to mosquitoes' spectral sensitivity and the trap produces gentle vibrations that excite the insects and draw them in. The trap emits infrared heat to simulate human body temperature and it produces the smell of octenol (the same chemical in human breath and sweat) to lure mosquitoes to the trap. As mosquitoes gravitate to the unit, a fan pulls them into a collection net where they are trapped and die of dehydration. An independent medical entomologist tested leading traps and the four attractant mosquito trap captured 1,343 mosquitoes per night, far superior to competing models that collected as few as 215. An integrated digital timer turns the trap on and off at any time (and any day) you choose. Includes one octenol strip that lasts up to 30 days. Plugs into AC with 60' cord. 22" H x 14 1/2" W x 12 1/2" D. (17 lbs.)
