The Vortex Electronic Insect Trap will keep insects from ruining your next picnic, camping trip or barbecue. This revolutionary insect trap attracts insects by creating carbon dioxide with UV light and titanium dioxide. Then a vacuum fan draws them in and traps them. This is a pesticide and odor free solution that will kill mosquitoes, flies, wasps and more! Take it anywhere and use it indoors or outdoors, day or night. It has an all-weather construction and uses four AA batteries (not included).
