How do bug zappers work

While you how do bug zappers work fun outdoors, many insects get to enjoy a good meal. Either they're eating your food or they're eating you. To clear your yard of these insects, you can try a variety of devices, ranging from simple Citronella candles to elaborate traps to pesticides such as Dursban to electronic bug zappers. A bug zappermore formally known as an electronic insect-control system or electrical-discharge insect-control systemlures bugs into it and kills them with electricity.

To investigate the effectiveness of bug zappers on mosquitoes, the Department of Entomology and Applied Ecology at the University of Delaware spent 10 weeks analyzing bug zappers. Altogether, over 13, insects were zapped and collected. Out of 13, zapped insects, l ess than 0. Out of 13, zapped insects, o ver Based on the study's results, bug zappers are killing beneficial insects like beetles and moths, which can result in negative effects on local ecosystems.

The sounds of Spring. Rain and thunderstorms, birds that are finally coming back after a long winter, and ZAP! That's right, it's time to talk about bug zappers, an invention that has come a long way since it was first patented in Bug zappers, despite many improvements in safety and insect luring potential, are basically the same as they were when first invented. An ultraviolet emitting light bulb attracts insects into a high voltage electrical wire mesh grid where the bugs are electrocuted. The light bulb and the wires are housed in a protective plastic or grounded metal cage. Most Zappers use fluorescent light bulbs that emit ultraviolet light to attract the insects. Why are bugs more attracted to ultraviolet light? Interestingly, the flower patterns that insects are attracted to are revealed in UV light! When the insect sees the UV light from the bug zapper bulb , it enters the space in between the mesh grids. The bug itself completes the electric circuit, and the voltage crosses the space between the circuits, instantly vaporizing the bug. The circuit closing is what causes the "ZAP" sound from the instrument. Obviously, bug zappers work. Just ask anyone who has spent time around a zapper at night, as each insect that is killed can make the signature ZAP noise.

Either they're eating your food or they're eating you.

Bug zappers kill bugs by the thousands. They are ineffective against mosquitoes and other biting flies, and their otherwise indiscriminate killing can disrupt pollination and generally throw the environment out of balance. Plus, the force of their electrocution can spew a mist of disease-ridden bug parts out into the air. All of the mosquito experts we spoke with and every relevant university extension office we could find unanimously condemned bug zappers. To keep an area free of bugs or to prevent yourself from getting bitten, there are much better alternatives.

A bug zapper , more formally called an electrical discharge insect control system , electric insect killer or insect electrocutor trap , is a device that attracts and kills flying insects that are attracted by light. A light source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic " zap " sound produced when an insect is electrocuted. Bug zappers are usually housed in a protective cage of plastic or grounded metal bars to prevent people or larger animals from touching the high voltage grid. A light source is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet light, which is visible to insects and attracts a variety of them.

Tallamy claims that bug zappers are worthless for reducing biting flies, exact a heavy toll on non-target insects and are counterproductive to consumers and the ecosystem. Altogether, over 13, insects were zapped and collected. Enough electric current flows through the small body of the insect to heat it to a high temperature. I also keep honey bees, which makes me a little more in tune with pollination and the insect world. Separately, William Brodbeck Herms — , a professor of parasitology at the University of California, had been working on large commercial insect traps for over 20 years for the protection of California's important fruit industry. It is an effective mosquito repellant in high concentrations, but individual plants do not make enough oil to be effective. They are ineffective against mosquitoes and other biting flies, and their otherwise indiscriminate killing can disrupt pollination and generally throw the environment out of balance. When we exhale, we emit CO2, which a female mosquito can detect from far away. Home Improvement. All of them indicate that bug zappers should be avoided at all costs. Mobile Newsletter chat dots. One final consideration is to keep zappers well away from any areas where humans will congregate for longer periods of time, or any food preparation areas. To learn more about bug zappers, we spoke to Laurence Zwiebel , PhD, a professor of biological science and pharmacology at Vanderbilt University.

Be sure to read product labels for usage directions. Article Talk. However, a better question to ask is whether zappers are effective at killing the most annoying bugs. Look for ONE of the following active ingredients on the label that is safe and effective against biting insects and the diseases they can transmit! Fun fact: Only the female mosquito bite because they use your blood to create her eggs. Experts cited in an article from the Wirecutter also concluded that bug zappers have the unintended consequence of killing beneficial insects. Problem solved. We have recommendations for both types in our guide to the best bug repellents. Professor Jonathan Day of the University of Florida also shared his expertise with us. To investigate the effectiveness of bug zappers on mosquitoes, the Department of Entomology and Applied Ecology at the University of Delaware spent 10 weeks analyzing bug zappers.
