Why are there always flies in the florescent lights at school?

Answer 1

The eye of the fly is made up of hundreds of tiny hexagonal lenses, which form a curved lattice across the of the eye. Unlike humans, flies can see ultraviolet light, due to the complex makeup of their eyes. Insects such as the House Fly, which are attracted to light, are said to be phototactic.

According to a website about the food manufacturing business, "Use lighting strategically. Flies are attracted to fluorescent lights, so if you mount these lights at least 100 feet from the entrance of your plant, it will help to draw flies away from entrances. At entrances that must have lights, install sodium vapor lights, which are less attractive to flying insects."

So flies must be attracted to something about the lights.

Another site hints that it might be the color of the light: "Placing outdoor lights several feet away from doors of homes and apartments also concentrates insect activity away from the sites where they cause the most annoyance. In addition, yellow light bulbs attract fewer insects that white incandescent lights or fluorescent bulbs. " http://edis.ifas.ufl.edu/IN080
