Nothing can be more annoying than insect pests biting you from right, left, and center when spending time outdoors. You become so uncomfortable that you only want to be is back inside.

Due to the inconvenience, these pests make you feel, insect electrocution light traps (or bug zappers) were made to solve the problem.

However, there are questions like: “do they really work?” “do bug zappers use a lot of electricity?” You are about to find out in this article.

What are Bug Zappers?

Bug Zappers (or Insect Electrocution Light Traps or Electronic Insect-control systems) are devices designed to lure and kill bugs and other insect pests using electricity.

Until 1911, there were other ways of killing insects and bugs without electricity. Popular Mechanics developed this idea of insect electrocution, and by 1932, the first patented bug zapper by William F. Folmer and Harrison L. Chapin was recorded (U.S. patent 1,982,439).

Since then, different manufacturers have emerged to develop zappers that would kill biting flies and flying insects. They constantly made adjustments and improvements in the design of their products so that they would be safe, easy to use, and effective.

How Do Bug Zappers Work?

From the basic features in the design of bug zappers, it is pretty much easy to understand how they work.

When the bug zapper is connected to a power source, the transformer increases the low voltage lights to lure the insects to the device. Most species of insects are more attracted to UV lights than visible lights (just like flower patterns being UV light).

As bug zappers stay on and ultraviolet light draws insects, they fly towards the light, penetrating through the electrified wire grid and wire-mesh. Once they complete passage, high voltage electric current flows through the insects or bugs and vaporizes them. You would probably have an electric crackle – a loud “ZZZ” sound, which means there are dead bugs.

In an area with a heavy population of bugs and insects, over 15,000 of them can be killed.

More so, bug zappers kill all types of insects – harmless insects, beneficial insects, non-target insects, and non-harmless aquatic insects. They don’t discriminate.

Do Bug Zappers Use Much Electricity?

No, they don’t.

Most bug zappers have been designed to use electricity as their power source. However, the interesting thing is that they do not consume much electricity.

For a large electric bug zapper, the highest they can use is 100 watts, even depending on how much you use it. On average, it could use 20 cents of electricity daily, even by switching two units on and leaving all night.

There are also small bug zapper light options, which mostly come as one unit that can use $8 worth of electricity per month on average.

Frequently Asked Questions

Can You Leave a Bug Zapper On All The Time?

Yes, you can.

Bug Zappers are devices that can constantly keep on working all day and night, as long as they remain connected to electricity. Even though they are most effective at night, considering the population of pests and bugs, they can also do great during the day.

Do UV Bug Zappers Work During the Day?

Yes, they do.

Electric bug zappers work during the day, as they work at night. The only difference is the efficiency. They can work more effectively in the evening because, in the insect breeding cycle, maturation time is often in the evening.
