Fruit Fly Bait

by John Priestley

 

  • 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.

    Good morning John,
    Could you pleaase tell me how long the bait is effective ?
    Has it got to be replaced regularly or when it is all evaporated ?
    Kind regards,
    Michel

  2. In my experience I replaced it every couple of weeks to a month because it either evaporates or fills with flies! Best to hang in a shady place where the flies prefer to rest. Maria
