How do bug zappers work

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, how do bug zappers work.

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.

While you have 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 zapper , more formally known as an electronic insect-control system or electrical-discharge insect-control system , lures bugs into it and kills them with electricity. In this article, we will examine the parts of a bug zapper, learn how this device works and discuss the controversies surrounding its use. We'll also look at some other bug-control devices that may make your time outdoors more pleasant. The first bug zapper was patented in by William F. Folmer and Harrison L. Chapin U. Although there have been many improvements, mostly in the areas of safety and lures, the basic design of the bug zapper has remained the same. These grids are separated by a tiny gap, about the size of a typical insect a couple of millimeters. The light inside the wire-mesh network lures the insects to the device many insects see ultraviolet light better than visible light, and are more attracted to it, because the flower patterns that attract insects are revealed in ultraviolet light. As the bug flies toward the light, it penetrates the space between the wire-mesh grids and completes the electric circuit. You often hear a loud "ZZZZ" sound when this happens.

The largest number 6, or 48 percent were midges and harmless, aquatic insects from nearby bodies of water. The light inside the wire-mesh network lures the insects to the device many insects see ultraviolet light better than visible light, and are more attracted to it, because the flower patterns that attract insects are revealed in ultraviolet light.

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. Experts and studies from Colorado State University Extension and the American Mosquito Control Association concluded that bug zappers are not effective at controlling biting mosquitoes.

Fly zappers have long been a popular method of fly control in commercial food handling premises such as take away outlets, cafes, delis, butchers, bakeries, commercial kitchens, food manufacturing and more. In fact, the fly zapper has been around for centuries with the first fly zapper believed to have been invented by Leonardo da Vinci in The first commercially produced fly zapper was invented in They get the name from the characteristic 'zap' sound created when an insect touches the electrical grid. Fly zappers are available in a range of different shapes and styles but all share the same basic characteristics. Fly zappers use ultraviolet tubes to attract flying insects into the unit, before 'zapping' them dead when they touch a high voltage killing grid. UV tubes attract flying insects by emitting a wavelength of light attractive to flies.

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. To learn more about bug zappers, we spoke to Laurence Zwiebel , PhD, a professor of biological science and pharmacology at Vanderbilt University. Vosshall has been studying insects for 30 years, with a focus on mosquitoes and repellency for the past 15 years.

October Mobile Newsletter banner close. Mobile Newsletter chat subscribe. Cover any rain barrels, and if you have a pond, stock it with fish that will eat the mosquito larvae. 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. Because of the irresistible lure of their light, bug zappers are incredibly effective at killing bugs. Some use a fan to help to trap the insect. The circuit closing is what causes the "ZAP" sound from the instrument. Folmer and Harrison L. Mosquitoes are attracted to this mixture, get sucked into a net, dehydrate and die. Another means of personal protection from biting and flying insects is citronella oil. In fact, traditional electronic bug zappers may be ineffective against mosquitoes, which, as we learned in the last section, are not necessarily attracted to the ultraviolet light. Anthony,The Florida Entomologist, Vol. A study from the University of Delaware tracked six residential bug zappers over a week period and found that of the 13, insects killed, only 31 were biting flies including mosquitoes.

The US Food and Drug Administration FDA advises that the bug zapper should not be installed above a food preparation area, and that insects should be retained within the device. The distance between adjacent wires is typically about 2 mm 0. We can help. The researchers claimed that killing this many harmless insects would disturb nearby ecosystems. 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! But not all pollinators are spared. While you have fun outdoors, many insects get to enjoy a good meal. Unfortunately, many biting bugs are not attracted to the UV light coming from bug zappers, mosquitoes and biting gnats included. Horticulture and Home Pest News. The light source is surrounded by a pair of interleaved bare wire grids or helices. Chapin U.
