This insect trap is engineered for 4-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. A third lure, water that is gathered in the water tray, attracts egg-laying insects. Fourth, a powerful yet whisper-quiet vacuum fan sucks insects into the retaining cage where they dehydrate and die. Convenient pole stand allows you to place the trap where you need it most.
