Fly traps that use an ultraviolet light source to attract flies are entirely safe. There is no worry about human exposure. The light source is basically a black light to attract the flies, and then the flies are captured on a stickly glue surface inside the trap known as a "glue board". The glue board is replaceable when it is full of flies. We recommend to change glue boards every 60-90 days for best results.
