Residents and businesses in parts of the Cities of Bayswater and Belmont have been called on to play their part in eradicating the serious horticulture pest, the Queensland Fruit Fly. The Queensland Fruit Fly is considered one of the world’s worst pests, attacking more than 300 fruits, fruiting vegetables and fruiting plants, as well as home gardens.

DPIRD Media Release 17 March 2023

A Quarantine Area has been declared for parts of the Cities of Bayswater and Belmont to support efforts to eradicate the serious agricultural pest Queensland fruit fly (Qfly), requiring residents and businesses to take action.  The move comes after recent detections of the damaging pest in Bayswater by the Department of Primary Industries and Regional Development’s (DPIRD’s) early detection surveillance trapping grid. While there have been no Qfly detections in the outer metropolitan horticulture production districts, the Swan Valley is included in a broader buffer zone requiring growers to follow movement directions for produce. The Quarantine Area has a small Corrective Action Zone covering a 1.5 kilometre radius around the detection point near the intersection of Frinton and Roberts Streets.

Action to Minimise Risk of Spreading Qfly Outside of Quarantine Zone: Home grown fruit and fruiting vegetables, like tomatoes, chillies and capsicums, cannot be moved out of or within the Corrective Action Zone, unless cooked, frozen or solarised. Unwanted fruits and fruiting vegetables can be treated by cooking, freezing or solarising before being disposed of in general waste bins. Ripe or ripening fruit and fruiting vegetables from home gardens must be picked regularly and all fallen fruit removed every three days and cannot be moved within or outside the zone unless treated. It is important that homegrown fruits and vegetables are not disposed of without prior treatment, as this risks spreading Qfly outside of the current zone.

DPIRD is working with Swan Valley growers, providing advice on the movement and treatment of commercial fruit within, out of, and through the Quarantine Area. Chief Plant Biosecurity Officer Sonya Broughton said the Quarantine Area was required for an efficient and effective biosecurity response and called on the community for support. “It’s important we all play our part to aid a swift response and prevent Qfly from further impacting our valuable horticulture industries,” Dr Broughton said. “Working together – industry, government and community – and adhering to the Quarantine Area directions gives us the best chance of eradicating this pest, which could impact growers’ livelihoods and access to valuable markets.”

An extensive DPIRD eradication campaign is underway, including inspections and baiting with a registered organic control, on street trees and trees on residential and commercial properties.

Qfly is considered one of the world’s worst pests, attacking more than 300 fruits, fruiting vegetables and fruiting plants, as well as home gardens. 

The department has vast expertise and experience in responding to Qfly detections in the metropolitan area, having eradicated the pest eight times in the past 40 years, most recently in the western and southern suburbs in 2020 and 2021. For a map, information on movement, treatment and disposal requirements and to stay up to date with the Qfly biosecurity response visit the DPIRD website
