This is the trap that attracts and kills mosquitoes across a full acre. It uses a LED bulb that emits UV rays to attract flying mosquitoes throughout the day and night. When the insects are drawn inside the device, an integrated fan traps the insects and sends them to a removable compartment where they die of dehydration. Unlike propane systems that require frequent refills or electrocution traps that release pathogens when an insect is killed, this mosquito trap does not create harmful biological agents. In addition to mosquitoes, it catches flies, moths, no-see-ums, beetles, wasps, yellow jackets, gnats, and biting midges. AC plug. 14 1/2" H x 12" Diam. (4 lbs.)
