Extend your range of protection with the AtrakaGlo enhanced illumination system. Protects up to 1 acre. Pesticide and odor free. Durable, all-weather construction. Provides 3-way protection against mosquitoes and other flying insects. A UVfluorescent bulb generates a warm light, attracting insects. Then a second lure produces CO2 (the same gas we emit whenwe exhale) that attracts the insects. Third, a powerful, yet whisper quiet vacuum fan sucks insects into the retaining cage where they dehydrate and die. A funnel confines flying insects to the retaining cage when the trap is turned off. No zapping or buzzing. No expensive attractant or propane required. Easy to set up.
