Baiting Information and Instructions

How do I make my bait mixture?

First, have you got your insecticide (Malathion)? Follow manufactures instructions when using the insecticide.

In an open necked container mix:

  1. 18gms of NATFLAV® ‘500’ (use a spoon and weigh this on scales),
  2. 300ml water and stir until mixed.
  3. Place mixture into spray bottle and add
  4. 3ml of Malathion, shake to combine.
  5. For each additional 100mls of water add an additional 6gms of NATFLAV® ‘500’ and 1ml of Malathion

How do I and where do I apply my bait mixture?

Wear protective clothing when applying bait.

a) Spray or paint the bait mixture onto either the upper trunk or branch of a tree, covering a minimum area of about 10cm2. This tree can be an ornamental tree. It does not have to be a fruit tree.


b) Spray the bait mixture onto the underside of foliage, avoiding any fruit if it is a fruit tree you are using. Cover a minimum area of about 10cm2.

If using either of these methods, the spray site should be high enough to prevent children and pets from touching the bait.


c) Another method can be to spray the bait onto a small piece of cloth and house the cloth in a disused drink bottle which has a large hole cut in both sides to allow the insects to enter.

Hang the bottle in a designated tree or in the vegetable garden.

How often do I have to replace the bait mixture?

Every 7 days and again if 5ml of rain has fallen after the last application. Wash hands after use.

How do I store my bait?

NATFLAV® ‘500’ must be stored in an air tight container and kept out of direct sunlight.  

Do not add any insecticide or water to unused NATFLAV® ‘500’  

Where do I get additional supplies of NATFLAV® ‘500’?

Spread the word

Control of Queensland Fruit Fly is only achievable if everybody becomes involved in the baiting program.  This includes your neighbours who may not be vegetable or fruit gardeners.

So speak to your neighbour and encourage them to become a Queensland Fruit Fighter.

Baiting alone is not enough.

Good garden husbandry is essential. If fruit, and this includes oranges and lemons, is not going to be used, then remove all fruit from the tree BEFORE they ripen so as to prevent fruit fly from laying their eggs in them.

Encourage your neighbours to do the same.

Gardeners, are you fruit fly ready?

Fruit fly season is fast approaching. For the past 3-4 years Queensland Fruit fly have commenced their spring emergence in late August/early September. They require high levels of protein (found in fruit) to build up the strength to commence breeding

Winter lemons and oranges, quinces, locusts are the key host fruits for adult fruit fly coming out of the winter dormancy period.

It is critically important that these first emerging fruit flies are not given a chance to breed and produce more fruit fly

So what needs to be done? Firstly, if you have winter producing citrus, consider what you can realistically use and remove from the trees that amount of fruit that would go to waste. This quickly reduces the availability of host fruit for fruit fly to lay eggs in.

Consider the height of your fruit trees. Can you easily reach the fruit at the tops of the branches? If not, consider pruning your trees so that all fruit can be readily removed.

Commence baiting with specific fruitfly baits (or spot sprays) around your yard. There are a number of products available from nurseries or garden centres, and Fight the Fruit Fly Association has available NATFLAV500, a protein bait, specifically designed to control fruit fly without impacting on all the other good insects in your garden.

Baiting must be undertaken on a weekly basis, right across the fruit fly season (approx August through to May each year. Baits work by mimicking fruit protein and attracting both male and female fruit flies. The bait mixture contains an insecticide which when ingested by the flies causes them to die.  You will not see evidence of dead flies, rather success is measured by having little or no evidence of fruitfly larvae in your fruit.

Beware that fruit fly traps only capture and kill male fruit fly. They do not attract female fruit fly.

In addition to baiting, gardeners could consider covering fruit trees with very fine netting such as mosquito netting or place paper bags over fruit.

Introducing control measures once you observe fruit fly maggots (larvae) in your tomatoes, peaches, plums oranges and lemons is too late.

About NATFLAV® ‘500’  

How do I know if I have Queensland fruit fly?

You won’t know you have fruit fly until you find your fruit and vegetables full of maggots (larvae).  

Commencing baiting at this time will not be effective in providing protection to your garden.

Adult fruit flies need to be killed before they have commenced laying their eggs.

Adult Queensland fruit fly will spend the winter hidden in the foliage of trees and shrubs in your garden, including gardens where there are no fruit trees.  During summer, flies will shelter under the leaves of shrubs and trees, including ornamental plants.  They are very small and difficult to see.  

How many baits stations do in need in my yard?

Baiting areas are known as “bait stations”. Ideally there should be no more than 5 metres between bait stations.

There should be at least one bait station in your front yard as well.

The more bait stations you have in your yard, the greater the chances of attracting large numbers of fruit fly.

How do I know if my bait stations are working?

You will not see many, if any, dead fruit fly in and around your bait station, including in the bottom of the shelter if that is the method you are using.

This is because the flies are very small and difficult to see and they do not die immediately.

Evidence of success is measured by having no fruit fly mgots in your fruit and vegetables when they have ripened.
