Mosquito Management in Western Australia: A Focus on Gosnells and Canning
Western Australia residents are being urged to take proactive measures to avoid mosquito bites, especially in the Gosnells and Canning districts, where Ross River virus cases have been recorded in recent years. The Department of Health's chief health officer, Dr. Andrew Robertson, emphasizes that the Ross River virus is a consistent presence across the state, with varying case numbers annually.
In the 2021-2025 period, the data reveals a concerning trend: six cases were detected in Gosnells and five in Canning. This highlights the importance of mosquito management in these areas. The City of Gosnells is taking a proactive approach by monitoring mosquito activity and implementing treatments at identified breeding sites during the 2025-2026 season. Their statement advises residents to follow the WA Department of Health's guidance for bite prevention, including wearing long, loose-fitting clothing and applying insect repellent.
The City of Canning, with the Canning River running through its heart, faces unique challenges. The river's aquatic environments, especially those influenced by tides, provide ideal conditions for mosquito breeding. The city's Mosquito Management Program targets salt marsh mosquitoes, known for their aggressive biting behavior and potential to transmit mosquito-borne diseases. Despite low Ross River virus case numbers, the program aims to reduce breeding, adult mosquito populations, and disease incidence.
This comprehensive approach includes inspections and treatments of mosquito larvae in breeding areas, regular trapping to monitor adult mosquito numbers, and community education. The city encourages residents to report increased mosquito activity and take precautions when spending time outdoors, emphasizing the importance of bite prevention in these districts.
