All-weather Skone Trap uses patented three-way insect control to provide up to 1/2 acre coverage of relief from mosquitoes and other flying insects ?without propane, repellants or toxins. First, two UV bulbs and CO2 lure insects to the trap. Then, a quiet fan draws them into the retaining cage where they perish naturally ?no pesticides!Once trapped, mosquitoes quickly dehydrate and die. Significantly reduces mosquitoes, biting flies, Asian beetles, wasps and other irritating insects from your indoor or outdoor living area. Plugs into standard outlet
