It is scientifically impractical to state the coverage of an Insect Light Trap. Whether or not insects get attracted to UVA rays is dependent on both distance and other light sources in the vicinity. However, our research (independently conducted at accredited laboratories) has repeatedly shown that the capture rate of flying insects is determined by the light output as well as the design of a trap. The distance to elicit a response from flies depends on insect types, structure layouts, and materials and ambient light in the surroundings.
