Every evening, a mass assassin stalks the darkness of America’s suburbs. An eerie blue glow lures hapless victims from their homes. The doomed souls, mesmerized by the sunshine, throng to their deaths in sizzling blasts of electricity. I’m talking about the bug zapper. Many people use the system to rid themselves of mosquitoes and other pests. "Kill flies, mosquitoes, gnats, and wasps," touts Black and Decker. Flowtron will help remove flying pests over up to "2 acres" for just $315. Another advertises itself as an "eco-friendly" solution to "instantly kill" mosquitoes. The issue? None of these claims are true, scientists say. Actually, bug zappers make it extra seemingly you’ll be bitten by mosquitoes while sitting in your yard. "When it comes to mosquitoes, bug zappers don’t work," says James Fordyce, an entomologist on the University of Tennessee at Knoxville. Bug zappers are distinctive killers of bugs - simply not the ones that bite you. Among the hundreds of insects these devices electrocute every evening, virtually all are harmless.



One examine estimated even a fraction of the bug zappers sold within the United States kill more than 70 billion insects annually - with no discernible impression on mosquitoes or other biting insects. This pointless slaughter of local insect populations may be hastening the decline of species, the insect apocalypse. I talked to specialists about why bug zappers are a extremely unhealthy concept to do away with mosquitoes - and what works instead. Bug zappers purport to work by attracting mosquitoes, sometimes utilizing a lightbulb that emits ultraviolet gentle, or typically carbon dioxide or chemical bait. Yet studies show virtually no mosquitoes or other biting insects ever enter a zapper. In 1997, Official Zap Zone Defender the University of Florida’s medical entomological laboratory tallied the loss of life toll from one bug zapper over a single night time: 10,000 insects. Just eight were mosquitoes. Similar studies mirrored these findings. Around the identical time, researchers on the University of Delaware used a bug zapper to lure 13,789 insects over a summer time.



Only 31 - 0.22 % - were biting insects such as mosquitoes and gnats. What did it kill? Beneficial bugs, largely. Roughly half the victims - 6,670 insects - were harmless aquatic species from close by rivers and streams, fish food in the aquatic meals chain. Many of the others have been parasitic wasps and beetles that naturally prey on mosquitoes. Mosquitoes will not be fooled by zappers because, together with different bloodsucking insects, Official Zap Zone Defender they've evolved to dwelling in on animals’ exhaled carbon dioxide, not ultraviolet light, scientists say. Even when mosquitoes are drawn in by a bug zapper, they are going to instantly redirect their attention to their favourite foods: warmblooded mammals, Zap Zone Defender particularly people. And Colorado State University’s extension service has reached the same conclusion: "No managed scientific examine has proven that these gadgets cut back mosquito biting charges outdoors," it states on its web site. None responded with materials supporting their claims after a number of inquiries.



Black and Decker referred all inquiries to a contract manufacturer, which additionally did not reply. These claims not only mislead buyers by ignoring scientific proof, however they might create a false sense of safety for individuals who use these devices to guard towards mosquito-borne diseases within the United States, Zap Zone Defender Fordyce said. "If one wish to avoid being bit, a repellent is the answer," he says. "Even if zappers worked … The FTC, whereas not commenting on the companies’ advertising and marketing statements, noted that it had investigated deceptive statements and safety points up to now issuing warning letters and filing circumstances against manufacturers of other varieties of pest control, comparable to ultrasonic gadgets. FTC officials recommended the general public submit any complaints via their website. What does repel mosquitoes? Bug zappers are just considered one of many suspect products promising to get rid of biting insects: ultrasonic units, propane-fired CO2 traps, and pesticide misters are among these that do not work, or do extra harm than good, according to Texas A&M.
