The Dynatrap portable indoor insect trap attracts and kills mosquitoes and other nuisance flying insects including pantry moths, flies, and Asian beetles. This insect trap is 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 insects into the retaining cage where they dehydrate and die. The trap weighs less than 3 lbs. and is about the size of a large thermos, enabling ease of portability from room to room and unobtrusive set up. A unique twist on/off feature ensures that any insects still alive in the retaining cage will not escape when the trap is turned off.
