How does Bug Zapper Work?

Are you annoying with the mosquito or insects when you are spending time outdoors?

I guessed you will say Yes, right?

To clear your yard of these insects, there are many varieties of devices you can try. Many people will use the insect electrocution lights, or bug zappers at their backyards to kill those biting insects. But does the bug zapper actually kill mosquitoes?

Well, without wasting any more time, let’s take a look at how the bug zapper performs.

Introduction of the Bug zapper

The first bug zapper was invented by William F. Folmer and Harrison L. Chapin in 1934, and they own the U.S patent, number 1,962, 439. Nowadays, the bug zapper has been upgraded for the safety and lures for many times, the basic design of the bug zapper has remained the same.

Bug zappers actually are quite simple. The basic parts of the bug zapper are:

· Housing -It is usually made of plastic or metal, in most cases, the shaped would be made as a lantern, a cylinder or a big rectangular cube. And to avoid children and animals to touch the electrified grids inside the device, the housing would have a grid design.

· Bulb – ultraviolet light to attract the insects (blacklight)

· Wire grids – Wire meshes surround the light bulb are supposed to electrify the insects and kill them.

· Transformer – It will increase the voltage 120V to 2, 000V or more, in order to kill the insects.

How insects find their target

Firstly, it is important to understand how these flying insects find their target to bite before you decide to buy a bug zapper product. In other words, you need to think about how the flying insects find someone to bite.

Well, it is carbon dioxide.

Most biting insects can easily detect carbon dioxide in the air. One of the research shows that a flying insect can detect carbon dioxide from as far as 35 meters away from its source.

After detecting the CO2, the insects will try to fly to the person or animal in that area.

Besides the carbon dioxide, those flying insects also use other ways to find their target to bit, such as perfume, sweat or body odor, etc.

How do bug zappers work?

Flying insects target their meals by tracing the carbon dioxide. Is that meaning that bug zappers never kill them?

No, of course not.

Bug zappers use ultraviolet light to attract mosquitoes or insects. Because many insects can see the ultraviolet light better than the visible light, so, that’s why many manufacturers will use UV light bulb in the bug zapper.

When the bug flies toward the UV light, it goes through the space between the wire-mesh grids and completes the electric circuit. High-voltage electric current flows through the insect and terminates it. And when this happens, you often can hear a loud “ZZZZ” sound.

Bug zappers can lure and kill more than 10,000 insects at one night. The bug zapper is not designed to eliminate certain types of insects, but due to the luring strategy, they tend to kill those insects that are most attracted to ultraviolet light.
