Working Principle:  Simply pour in the bait, then add water to the fill line and swirl to mix. Add more water as needed to keep the bait moist and flies submerged.

Hang the fly trap bottle between the crown and the tree top, preferably outside the orchard and on non-fruiting trees, with a height of about 1.5 meters. Use 5-10 per acre of orchard for the best effect.
