How Bug Zapper Works?

To begin with, You should understand the mechanism of how a bug zapper works. A bug zapper is not technical in operation. The bug zapper body parts are the housing, light bulb, wire grids or screens, and transformer.


This is mainly made of plastic or metals that are already electrically grounded. It is shaped like a lantern, a cylinder, and it can also come with a grid design made to avoid electric shock on children.

Light bulb

The essence of having a light bulb is to lure the attention of bugs and any other insects. The light bulb is a fluorescent light. It can be mercury, neon, or ultraviolet, generally black light. So, it is established that the light bulb attracts bugs.

Wire screen or grids

Wire metal grids surround the light bulb and are always electrified to kill the insects drawn by the light bulb.


As this sounds like, it is the powerhouse for the wire grid. It powers the wire grid, changing the average 200V to an electrifying 2000V.

The high voltage is passed across the wire grid. You might be wondering how this wire grid kills the insects. The wire grids are just apart in millimeters, about the size of an average insect. The mental picture you have right now is precisely what happened. The light bulb lures bugs, they try to get the light bulb, but the electric shock kills them.

The light is more attractive to insects because they see ultraviolet light than visible light. The flower pattern also has a way of attracting the insect when lit up. Any insects or flies, insect pests, pesky insects, wasps, ants, moths, mosquitoes, flying insects, or beneficial insects can be victims if they are drawn to the UV light.

On seeing the UV light, the insects move towards the bug zapper. They try to go in through the space between the wire screen. The insects touch the grid on both ends, completing the circuit. The electric shock does its job, and then the insects vanish into thin air for lack of words. At this point, you will hear some sounds from the bug zapper.

Bug zappers are strong and can destroy thousands of insects or bugs in a day. The device doesn’t just work on bugs, and it works on any insect as long as the UV light can lure them. This can also mean that it can not work on all insect species.
