A Bigger Design for a Bigger catch. This Dynatrap Insect Trap attracts and kills mosquitoes and other flying insects across 1 Acre. This insect trap is engineered for 3-way protection against mosquitoes 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 mosquitoes. Third, a powerful yet whisper-quiet vacuum fan sucks insects into the retaining cage where they dehydrate and die. A damper closes when the trap is turned off to prevent insects from escaping.
