Pesticide and odor free insect trap with 1/2 acre coverage. Perfect for your urban or suburban yard. Features an all-weather construction to use rain or shine indoor or outdoor. This 1/2 acre trap attracts and kills mosquitoes and other nuisance flying insects including biting flies, wasps, stink bugs, hornets, yellow jackets, no-see-ums, Asian beetles and more. Engineered for 3-way 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 the insects into the retaining cage where they dehydrate and die. Our patented damper flaps ensure any insects still alive in the retaining cage will not escape when the trap is turned off. Includes a cleaning brush, 24 inch chain for hanging and a screwdriver. DynaTrap does not attract honey bees or butterflies. For replacement bulb use Sku RTXC-5051.
