Pink Guava juice is high in vitamins & nutrition.  What isn't welcome is a high concentration of pesticides.  The plantation management decided on a reduction in pesticides ( & ultimately elimination) with a simple & effective method.  Strategically place a lamp in the middle of the field to attract the pests at night, let them buzz themselves to death flying around the lamp.  Dead from exhaustion, the insects are simply dumped out the next day from the collection bin below the lamp.  The remains are also examined for the type of pests caught & those that were not attracted to the lamp.

Neat idea, except that the battery running the lamp needed to be charged daily and it isn't light (pun intended) We helped add a solar panel system to the unit.  It now works everyday without having to have its battery carried back and forth,to be recharged, much to workers' relief.  The plantation is now trying variations on the original design to build better insect traps.

All this so that they can proudly proclaim on their bottles "Pesticide Free!" .... artificial flavours not inlcuded.
