It attracts and kills mosquitos and other flying insects across 1 Acre. This insect trap is engineered for 3-way protection against mosquitos and other flying insects. First, a UV fluorescent bulb generates a warm light, attracting insects. Then a second lure, an exclusive Ti02 titanium dioxide-coated surface, produces CO2 that's irresistible to mosquitos. A damper closes when the trap is turned off to prevent insects from escaping. Size: 13" W x 13" D x 20" H.
