That forgotten orange on the tree or fallen fruit beneath your backyard branches could be more than a garden nuisance. It could help Queensland fruit fly (Qfly) populations grow and create bigger problems for local fruit and vegetable growers.
The first fruit fly update for the 2026-27 season has identified activity across the Goulburn Murray Valley, with 307 traps monitoring populations throughout Greater Shepparton, Moira, Campaspe and Strathbogie shires.
While most commercial horticultural crops are still too immature to be vulnerable, backyard fruit is already at risk. As the weather warms, adult flies are emerging from their winter refuges and moving into surrounding communities in search of suitable fruit.
Urban gardens can provide food and shelter for fruit fly populations, which may later move into commercial crops as harvest approaches.
So, what can residents do to help?
The message is simple: don’t leave unwanted fruit hanging around.
Pick ripe or unwanted fruit from trees, collect fallen fruit from the ground and remove neglected fruit from overgrown or weedy areas. This helps reduce opportunities for fruit flies to lay eggs and contribute to growing populations.
Current hotspots include Avenel, Merrigum, Cobram, Shepparton East, Nagambie, Kialla East, Kaarimba and Orvale.
Residents living near commercial orchards, particularly in these areas, are encouraged to check their own gardens and look out for unmanaged fruit trees nearby. This could include fruit on neighbouring properties, along roadsides, beside creeks or on channel banks. Where fruiting plants cannot be managed directly, residents can report them to the relevant landowner.
Fruit fly numbers typically begin rising in September, increase more sharply in December and peak during autumn. With October temperatures expected to remain warm enough for mating, action now could help reduce pressure later in the season.
A quick backyard clean-up today could make a real difference to protecting the region’s valuable horticulture industry.
