The annual swarms of fruit fly in Queensland are expected to surface earlier and stronger this year.
Entomologist Dan Papacek says winter has well and truly thawed and fruits are blossoming, creating an early banquet for swarms of fruit flies.
He says because he's built up such good fruit fly defences with citrus producers in the North Burnett, it's important people don't become complacent.
He's urged people to start preparing now, while considering changes to pesticide controls.
"With the loss of some of these older generation pesticides that are sort of on the way out, we're trying to urge growers to look at using a systems approach. And that is to monitor closely, and to apply protein bait sprays, and the third part is to use male annihilation."
