00:00Every summer, millions of homeowners hang up glowing blue bug zappers,
00:04listening to that satisfying zap sound, and believing their backyard is finally mosquito-free.
00:10But what if I told you that iconic blue light is actually doing more harm than good?
00:15Here is the frustrating reality. Mosquitoes are practically indifferent to ultraviolet light.
00:20While moths, beetles, and harmless aquatic insects fly blindly into UV traps,
00:26mosquitoes don't hunt by vision alone. They hunt by scent.
00:30They are drawn to the carbon dioxide you breathe out, body heat, and chemicals in human sweat.
00:36In fact, multiple university studies found that out of thousands of insects killed by bug zappers,
00:42less than 1% were actually biting mosquitoes. So what is that machine actually zapping?
00:47It's wiping out beneficial insects, like lacewings, beetles, and midges,
00:52that serve as vital food for songbirds, bats, and frogs.
00:56Even worse, when a bug zapper explodes harmless insects,
01:00it sprays a mist of insect particles and bacteria into the surrounding air near your patio.
01:06If you really want to stop mosquitoes, ditch the zapper.
01:09Focus on eliminating standing water, setting up oscillating patio fans,
01:14or using traps that emit carbon dioxide.
