In order to fly straight ahead, moths always hold a 40-degree angle to the moon. This only works because the moon is so far away and therefore represents a fixed point. However, if a moth encounters artificial light, this becomes the brightest point. This source is far too close, with which the moth has to constantly correct its course in order to maintain the 40-degree angle. As a result, instead of flying straight ahead, it flies a curve in ever narrower paths towards the light and burns up. The construction of several light traps at the new moon and in the low spectral range is used on December 2nd to protect a few attractants, e.g. painted woolen blankets, perhaps also birdseed. Papers containing biocides offer double protection. Means and antidotes at the same time are a method of confusion in order to at least slow down the deterioration of the substances.
