Can a fly zapper kill a human?

A fly zapper is designed to attract and kill insects using high-voltage electric grids. While the voltage is typically not high enough to be lethal to humans, it can cause a painful shock if a person accidentally comes into contact with the grid. However, the risk of serious injury or death from a fly zapper is extremely low and unlikely in normal circumstances. It is important to use these devices according to the manufacturer's instructions to avoid accidents.
