PROBLEM TO BE SOLVED: To provide an insect attracting prediction method that can grasp an effect to an ecosystem by lighting equipment over during a construction period.SOLUTION: An insect attracting prediction method includes: an insect attracting database preparation step a temperature data base preparation step a construction period setting step of setting a construction start date and a construction end date a light source type setting step of setting the type of a light source of lighting equipment a light quantity setting step a light leakage situation setting step an introducing amount setting step of setting the kind and amount of insects one day prediction steps S304, S311 of predicting the kind and amount of the insects by one day attracted from a peripheral region using the lighting equipment, from an insect attracting database, an annual temperature transitivity, the type of the light source, light quantity, the type of an area and environment, and the kind and amount of the insects introduced into a light leakage area, for every one day from the construction start date to the construction end date and an accumulation step S308 of accumulating the kind and amount of the insects attracted in one day predicted in the one day prediction step, from the construction start date to the construction end date.
