DynaTrap XL Outdoor Flying Insect Trap 1 acreIf you have an extra large mosquito or flying insect problem, the DynaTrap XL Mosquito and Insect Trap delivers three layers of powerful protection. 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.
