Yesterday on the show we talked about the fight against the fall armyworm after the unwanted invasive species was discovered in Northland.
We had lots of feedback, including one from a listener who asked us to talk about the invasive cluster flies, describing them as "like a biblical locust plague".
So we set about finding the best expert on cluster flies, that person is Entomologist and Pest Management Association vice president, Dr Paul Craddock. He speaks to Jesse.
