How Mini Hexagon Solar Mosquito Killer Lights' Insect Killer Works
Insect zappers are basically the same as when they were first invented, despite many improvements in their safety and potential for attracting insects. An ultraviolet-emitting light bulb attracts the insects to a high-voltage wire mesh, where they are electrocuted. Bulbs and wires are housed in protective plastic or grounded metal cages.
Most use fluorescent bulbs that emit ultraviolet light to attract insects.
Why are bugs more attracted to UV light? Interestingly, the flower patterns that the insects are attracted to reveal themselves under UV light!
When the insect sees the UV light from the bug light, it enters the space between the grids. The bug itself completes the circuit, and the voltage passes through the space between the circuits, instantly vaporizing the bug. A closed circuit is what causes the sound from the instrument.
