  • 40 ml Cloudy ammonia
  • 2ml vanilla extract
  • 1 cup sugar
  • 2 litres water


I mix all ingredients together then divide the liquid into four 2 litre plastic milk containers which I have made a row of holes (with a hot soldering iron !) around the halfway mark. Then hang them around the perimeter of the fruit fly exclusion area.
