Biosecurity alerts: Queensland fruit fly updates

What happens during an eradication program

Action is taken in accordance with the Australia Fruit Fly Code of Practice. This includes establishing three zones. Different restrictions apply to each zone.

  • An Outbreak Zone around a 200m radius of the detection point (baiting concluded 18 August 2018, surveillance ongoing).
  • A Quarantine Area around a 1.5km radius of the detection point (movement and disposal restrictions on home-grown fruit and vegetables will remain in place until at least November 2018).
  • A Suspension Area around a 15km radius of the detection point (host fruit cannot be exported from within this area without treatment or other approved protocol).

Quarantine Area restrictions


Home-grown fruit and vegetables cannot be moved out of a Quarantine Area, and must be disposed of according to strict guidelines.

Nobody wants Qfly in Western Australia. To eradicate this pest we need the participation and support of residents and businesses within the Quarantine Areas as we carry out our response activities.

The department is exploring all avenues to remove pathways through which Qfly can spread to other areas. This includes:

  • Community gardens and public property where fruit trees are located. If within the Quarantine Area, the same rules apply to fruit and vegetables grown on these properties.
  • Online trading of fruit. Many properties have an excess of citrus during winter. Sellers at this time located within a Quarantine Area must remove their advertisements until further notice.
  • Home gardeners and gardening contractors must ensure that greenwaste is not disposed of before being stripped of fruit and vegetables. This includes greenwaste put out for verge collection. Fruit and vegetables must then be disposed of according to disposal guidelines.


The Quarantine Area Notice stipulates that ripening and fallen fruit must be disposed of every three days. Regular removal of fruit means that fruit fly will be unable to lay eggs and start the breeding cycle. Disposing of fruit and vegetables according to the guidelines below will kill any eggs or larvae.

Where fruit is inaccessible, wait until it has fallen to the ground and then dispose of accordingly. 

Disposal options include:

  • Eating or cooking (boil or microwave).
  • Freezing (minimum 24 hours).
  • Solarising - place in a sealed, heavy-duty black plastic bag which is placed in direct sunlight for three days.
  • Soaking - place in a bucket or large container of water with a film of white oil for at least seven days.
  • Burying to a depth of at least 1 metre as Qfly adults can emerge from under the soil surface.
  • Do not give away any home-grown fruit or vegetables.

Only after boiling, solarising or freezing you can:

  • Feed it to poultry.
  • Compost it.
  • Put in the rubbish.
