Quarantine Area in place to protect from Queensland fruit fly

11 December 2024

The Department of Primary Industries and Regional Development (DPIRD) has declared a Quarantine Area to contain the spread of Queensland fruit fly (Qfly).

The Department of Primary Industries and Regional Development (DPIRD) has declared a Quarantine Area (QA) for the City of Melville to contain the spread of Queensland fruit fly (Qfly) which was recently detected in the Willagee and Palmyra areas. 

What is Queensland fruit fly (Qfly)? 

Qfly is a significant pest of horticulture and home gardens that infests more than 300 types of fruit, including fruiting vegetables like chillies, capsicums and tomatoes. 

  • 6mm – 8mm long 
  • Red-brownish torso with yellow patches and a dark brown abdomen 
  • Clear wings

Quarantine Zones 

The Quarantine Area includes two zones – a corrective action zone around where the pest was first found (Red Zone) and a buffer zone of surrounding suburbs within a 15 kilometre radius of the initial detections (Orange Zone). 

An online interactive map can assist residents and businesses to identify what zone may apply to them and what rules apply.  Residents in the red zone are required to remove fruit and fruiting vegetables from all Qfly host plants and 'eat it or treat it' - see our Waste Changes due to Queensland fruit fly page for up-to-date instructions and advice for City of Melville residents and businesses. For a full host plant list and detailed information about the QA, please refer to wa.gov.au/qfly 

We understand that removing all host fruit from your garden is a sacrifice - it is a temporary measure but a powerful one that is designed at limiting the risk to your garden in the long term.  If Qfly is not eradicated, we risk our farmers losing access to valuable export markets and backyard gardeners losing the ability to grow many fruit and vegetables without the ongoing use of pesticides. 

What to do if you see a Qfly?
Please report any signs or sighting of Qfly, including maggots in fruit, to DPIRD's Pest and Disease Information Service on (08) 9368 3080 or email padis@dpird.wa.gov.au
 
Alternatively, you can send photos via the department’s MyPestGuide® Reporter app: www.agric.wa.gov.au/pests-weeds-diseases/mypestguide 
 
If I’m in the Quarantine Zone, can I still eat fruit from my tree?
Homegrown fruit and fruiting vegetables inside the Quarantine Zone can be consumed, however only treated fruit can be moved within or outside the zone.  
 
Treatment options include cooking, processing, freezing or solarising by securing fruit in a black plastic bag and placing on a hard surface in direct sunlight for more than seven days.  For more information, visit our Waste Changes due to Queensland fruit fly page.
 
What action is the Department of Primary Industries and Regional Development (DPIRD) taking?

DPIRD officers are undertaking inspections and baiting with a registered organic control on street trees, and those on residential and commercial properties. Residents should be aware that DPIRD officers may need to access private land in order to conduct trapping, inspections and baiting on host trees and plants.

Teams are currently hand-delivering letters to key-affected areas (starting with Willagee), while carrying out their eradication activities. If you have received a card in your letterboxes, please contact DPIRD to discuss appropriate access.

DPIRD is working to raise awareness of Qfly in affected areas through the use of outdoor signage, posters, advertising, and engaging with local radio and media.

How likely is it that we can eradicate Qfly?
DPIRD has vast expertise and experience in responding to Qfly detections in the metropolitan area, having eradicated the pest nine times in the past 40 years. 

The most recent responses were in Bayswater and Belmont in 2023, Dalkeith, Claremont and Nedlands in 2020 and Coolbellup in 2021.

Will infected trees need to be removed?
Trees will not need to be removed as part of DPIRD’s Qfly biosecurity response, as effective treatments are available to control the pest.
