All the great Dynatrap features now enhanced with the natural attracting power of H2O, The Dynatrap® DT1200 attracts and kills mosquitoes across ¾ -acre without harmful chemicals, The trap emits odorless carbon dioxide (the same gas people expel during respiration), light, and has a removable water tray to collect rain water to lure mosquitoes, Carbon dioxide is generated when ultraviolet rays from the internal fluorescent bulbs react with a titanium dioxide coating inside the trap, When the mosquitoes are drawn inside the device, an integrated fan traps the insects and sends them to a removable compartment where they die of dehydration, Unlike propane systems that require frequent refills or electrocution traps that release pathogens when an insect is killed, this superior model uses 3,000-hour rated UV bulbs and does not create biological agents, Sets up on the included stand, Plugs into AC with 7" cord, 44"" H x 13 1/2"" Diam, (15 lbs, ), Item Length: 12, 6"", Item Height: 44"", Item Width: 12, 6"" SKU: DYSLW005
