Information for Households
Remember, almost every type of fruit and fruiting vegetable is a potential host for fruit fly.
QFF is controllable - but each season there are things to do in your back yard and it is best to use a number of control options to minimise the damage.
Gardens are ideal places for QFF to live as they are warm and humid and provide food and shelter. Gardens with many different fruit varieties and vegetables that ripen all year round provide ideal conditions for QFF populations to rapidly increase in numbers.
Prevention is the best option.
Control strategies for homeowners need to be applied early and continuously after fruit set. Flies become active in mid-August as the weather warms up but will mate when the temperature reaches 15°C - and then start laying eggs. Once the eggs have been laid in the fruit it is too late to start control. Prevention is the best option. By starting to monitor and control fruit fly 6-8 weeks before harvest (while fruit is hard and green) fly numbers can be dramatically reduced when the fruit is ripe.
If you can't get rid of fruit fly, despite your best efforts, you need to make sure you are not the cause of infestations for our valuable horticultural industries. Click here to find out about our Tree Removal Program.
Vegetable gardens also provide a place where the adult female fly can lay her eggs. When planning your vegetable garden choose varieties that don't host fruit fly and makes it harder for fruit fly to lay their eggs.
Ornamental Fruit Trees
You may also need to inspect your garden for ornamental fruit that may host QFF. In Sunraysia, QFF has been detected in ornamental (Manchurian) pears, ornamental plums, lilli pilli, prickly pear and even rosehips!
Not sure what to do when. Each season there are things you can do to control QFF in your backyard: click on the season below to see the jobs for each season.

Fruit fly activity increases as weather gets warmer.
QFF may infect green fruit so control must start early and continue until all fruit and vegetables are harvested.
