What is the maximum distance over which an ILT can effectively attract insects?

The maximum distance over which an Insect Light Trap (ILT) can effectively attract insects varies significantly between different types of insects. For moths, studies have shown that they can be attracted from further distances, effectively reaching up to about 100 feet under optimal conditions. Meanwhile, flies have a much shorter attraction distance, typically around 25 feet. The distinction made in this answer reflects the understanding of insect behavior and the effectiveness of light trapping.

The prognosis for these distances is based on how these specific insects respond to light, with moths being more positively phototactic and thus attracted over longer distances compared to flies. Understanding these variations is crucial for effective pest management strategies, ensuring that traps are placed in locations where they can attract and capture insects efficiently.
