    Insects are naturally attracted to light.

    Is your question "why are insects attracted to light"?

    I did some research, and this is what I came up with. Hopefully this is helpful.

    Not all insects attracted to light act on those impulses. For some insects, a bright light source is seen as a emergency beacon. When in doubt, they will instinctively head for the light, which is generally higher than their current danger-filled position. Moving towards the dark would be seen as a move downward, which can be even worse than not moving at all. Light for some insects could be viewed in the same way as air bubbles pointing the way up to the surface for other creatures.

    Another popular theory is that insects attracted to light use it as a navigational aid. An insect flying north, for example, could judge its direction by keeping a natural source of light such as the sun or moon on its right side. This method works well as long as the source of light remains constant and at a distance. If an insect encounters a round incandescent porch light, however, it becomes confused by the light source. A moth will continue to circle a light because it instinctively wants to keep the light on a certain side of its body while navigating.

    The difference between insects attracted to light and insects not attracted to light is a phenomenon known as phototaxis. Certain insects such as cockroaches or earthworms have negative phototaxis, meaning they are repelled by exposure to light. Moths, flies and many other flying insects have positive phototaxis, meaning they are naturally attracted to light.

    Because they always want to die....that's what humans do when they do they go into the light.
